Allen Bradley VFD Repair

Allen Bradley VFDrepair is less expensive and quicker than Allen Bradley VFD replacement.The most economical way to get an Allen Bradley VFDrepair is by going directly to an Allen Bradley VFD repair center such as Precision Electric, instead of using a local vendor who doesn’t even perform the VFD repair themselves.Precision Electric performs all Allen Bradley VFD repair in house.

Checking the motor and drive terminal connections is a step many people miss or do incorrectly during an Allen Bradley VFDrepair. Heat cycles and mechanical vibration can lead to sub-standard connections, as can standard preventative maintenance practices. Reusing torque screws is not a good Idea, and further tightening an already tight connection, can ruin the connection. Bad connections eventually lead to arcing. Arcing at the drive input terminal can result in nuisance over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the drive output terminal could result in over-current faults or even damage to the power components.Loose connections can cause erratic operation. For example, a loose START/STOP signal wire can cause uncontrollable drive starting and stopping. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, or personnel injury.

Conduct Diode and IGBT Tests
There are a number of methods to test the input and output power sections during an Allen Bradley VFDrepair, and this step is done prior to applying power to the drive unit. If for any reason there is a short on the input side or output side of the drive, further damage can be caused to the unit if power is applied to it.For this reason, Precision Electric uses meters to properly test the input and output power sections of the drive prior to applying power to the actual unit. If a short is found, the unit can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the Allen Bradley VFD repair is too costly, then, VFD replacement is offered to the customer.

Power Up Unit
If the input and output power sections test healthy during the Allen Bradley VFDrepair, Precision Electric will power the unit and perform amp reading and output frequency tests. Precision Electricslowly increases the power voltage during this step of the Allen Bradley VFD repair. The power voltage is slowly increased on the Allen Bradley VFDuntil the rated input voltage of the drive is reached. Depending on whether or not the Allen Bradley VFDprovides a display will determine what further action will be taken. If display is unavailable, disassembly and diagnosis of the internal power supply of the control section of the drive is necessary to further evaluate cause of failure and establish cost and lead time for the Allen Bradley VFDrepair.

Run A Motor
If the previous three tests have passed during an Allen Bradley VFD repair, Precision Electric willrun a basic jog function of the drive with a simple template program. When a VFD comes into our facility, we make sure to backup all existing programs stored in the drive prior to inputting a template program to run a test procedure. This ensures that we have a backup copy of the program.The best method for backing up depends on the brand of drive, but after it has been backed up, we perform a basic reset of the Allen Bradley VFDto factory defaults through the keypad andthenrecommission a basic start, stop and job application or closed loop if an encoder is involved. If the motor will not run, it will be necessary to check the output voltages and current ratings going to the motor to see if the drive is functioning properly to rotate the motor.

Routine Maintenance
Most Allen Bradley VFD repair / failure can be prevented with routine maintenance. Allen Bradley VFD repair cost and lead times can also be reduced with routine maintenance. Allen Bradley VFDrepair can be expensive and cost manufacturers production downtime during the repair process. Most manufacturers keep spare drives in stock to prevent production downtime during the Allen Bradley VFD repair.

Allen Bradley VFDrepair should be taken with extreme caution and only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing all industrial electrical equipment. Many drive controllers have an internal DC bus that retains a charge after power has been cut to the drive, as a result, it does not mean it’s safe to work with. Technicians working Allen Bradley VFDdrives and other electrical equipmentmust always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.

Most companies who offerAllen Bradley VFDrepair do not even perform the repair in their facility. These companies outsource the repair to a third party such asPrecision Electric.

Eaton SV Repair

Eaton SV Repair

Eaton SV repairshould be taken with extreme caution andonly be performed by technicians who have required training and experience with electrical equipment. Alwaysconsult an expert in the field when repairing or troubleshooting industrial electrical equipment. Most drive controllers have an internal DC bus that retains a charge after power has been cut to the drive, as a result, the power being cut doesn’t mean that the drive issafe to work with. Technicians working with variable frequency drives and other electrical equipmentmust always take extra precautions to ensure proper safety measures are taken to prevent injury or even death.

Variable Frequency Drives (VFD’s) have over the past decade allowed to become a cost efficient way to reduce power costs and increase system efficiency. Manufacturers around the globe within a wide range of industries are finding more ways to apply VFD’s to their rotating equipment.From past experience, smaller horsepower VFD’s typically fail in eight years and are more often replaced rather than repaired.Larger horsepower VFD’s last longer by virtue of repairs that often require replacement of circuit boards and other electrical components.

Eaton SV Repair Versus Eaton SV Replacement

Eaton SV repair is common for Sullair Service Centers and manufacturers who use Eaton equipment. Eaton SVrepair is preferred by Sullair service centersand manufacturers because Eaton SV replacement is more expensive than Eaton SV repair.Most companies who offer Eaton SV repair don’t have the capabilities or experience to repair Eaton equipment themselves; so they outsource the VFD repair to third party repair centers, or they send it to Eaton and charge their customer more than the actual repair cost. Eaton offers SV VFD repair services for their products but it’s inefficient because Eaton always has extensive lead times for repairs, and Eaton drive users cannot wait forextensive lead times due toproduction downtime.Precision Electric offerscomplete Eaton SVrepair, and all Eaton SVrepair jobs are performed in house at Precision Electric.

Eaton SV repairis an asset to manufacturers who use Eaton VFD equipment because Eaton usually recommends replacing their equipment when it fails. Eaton SV VFD replacement is more expensive than Eaton SV repair. Eaton SVreplacement also has extensive lead times that aren’t economical when production is down. Eaton SVrepair can be performed by Certified Eaton SV Repair Centers morequickly than waiting for Eaton to produce a replacement SV VFD.

SVX9000 VFD Repair AndTroubleshooting

VFD failure is a common problem among Eaton VFDusers. VFD failure is mainly caused from equipment reaching the end of its life cycle orneglecting routinemaintenance.SVX9000 VFD repair can be repaired by Eaton Corporation but EatonCorporationtakes a long time to diagnose and repair their own equipment. Most of the time Eaton will hold onto a manufacturers VFDfor months and then tell them that the drive must be replaced because it cant be repaired. Precision Electric often repairs SVX9000 VFD equipment afterEaton has deemed the equipment “not repairable”.

Most SVX9000 VFD repair can be prevented with routine maintenance. SVX9000 VFD repair cost and lead times can also be reduced with routine maintenance. All VFD repair can be expensive and also cost manufacturers production downtime during the repair process. Most manufacturers keep spare VFD units in stock to prevent production downtime whenthe VFD repair isin process. Precision Electric trained technicians follow these steps when performing SVX9000 VFD repair:

Connections

PET Blow Molding

The increasing requirements being placed on food and beverage manufacturingare accompanied by growing demands on the machines in the consumer goods industry. The endcustomers in this industry are demanding machines and production lines with maximum availability, while calling for flexible product retooling and formatchanges as well as simple, consistent operator control of the machinery. Long maintenance intervals, clear error messages, the speedy worldwideavailability of spare parts and enormous energy efficiency for the machines are also important for success. Only acompany that effectively masters all the challenges it faces can be successful in the marketplace.Lenze offers the most modern automation and motion technology for the consumer goods industry based on the three standards of cost awareness, maximumquality and flexibility.

PET blow molding with Lenze Motion Centric Automation is a complete solution: bottles are formed, filled, capped and labeled. Motion Centric Automation from Lenze is the easy way to secure smooth procedures in almost anybeverage line. Lenze offers Motion Centric Automation products for PET blow molding to ensure that all processes remain simple and free of any problems.Motion Centric Automation from Lenze is a complete manufacturing solution from start to finish for PET blow molding processing. Below are the steps used with Lenze Motion Centric Automation products duringPET blow molding processing.

Applying even heat and air to create the perfect form is the first step in PET blow molding. The preforms are separated by the automatic preform loader and transported upwards to create the perfect form for PET blow molding process. Gravity thenallows them to slide into the in-feed wheel, from where they are loaded onto the transport chain. Infrared lamps in the heater heat up the preforms inrotation, whereby the neck of the bottles is held in shape at a lower temperature. The thermal treatment is combined with ventilation. At the heaterexit, arms of the PET blow molding carousel pick up the preforms below the neck. The form is completed and blowing process begins. The nozzle is lowered intothe preform and lateral pre blowing begins, followed by high pressure blowing, which presses the bottle wall against the mold. After cooling, an arm thenloads the bottles onto the transport chain.

Filling And Capping
Filling quickly, precisely and without interruptions: the empty PET bottles are conveyed to the filler carousel by the transport chain. The filler nozzleis quickly lowered into the empty bottle and starts to fill it, whereby a FlexCam cam profile ensures that any formation of foam is largely avoided.During the process, the nozzle is slowly moved up to match the fill level until the bottle is full.

When closing bottles at high speed, productivity is key: the transport chain moves the filled bottles to the capper. This presses the preheated caps overthe bottle thread and the bottles are then closed via torque-controlled rotation. Once this is complete, the closed bottles are sent to the labeler.Individual selection of drive components based on power requirements and the dynamic performance required. Highly dynamic servo drives and compact asynchronous motors with large speed setting ranges for all areas of bottle conveying benefit from a systematic arrangement: the finished bottles arrive in a single row, arranged one behind the other. The Cartesian coordinate robot picksup three or four bottles and lays them sideways onto a second conveyor belt. A touch probe sensor detects when enoughbottles are lined up at the end of the in-feed belt. The Cartesian coordinate robot then picks these up, controlled via a fixed motion profile for grouping.

Labelers
Precision is critical during wrap-around labeling: a rotary worm screw loads the bottles into the carousel, where they also rotate. In the labelingstation, a servo-driven transport roller continuously draws labels from the web, while the web guide guarantees straight-line label pick-up. The labelsare then cut to the precise size in a servo-controlled trimming process and two narrow strips of hotmelt adhesive are applied. The labels are thenapplied to the rotating bottles, after which the finished bottles are transported for secondary packaging.

Pick-And-Place
Benefit from a systematic arrangement: the finished bottles arrive in a single row, arranged one behind the other. The Cartesian coordinate robot picksup three or four bottles and lays them sideways onto a second conveyor belt. But how does the grouping work? A touch probe sensor detects when enoughbottles are lined up at the end of the in-feed belt. The Cartesian coordinate robot then picks these up, controlled via a fixed motion profile.

Film Wrappers
The next stage is packaging: here, the bottles previously arranged in groups of three or four arrive at the film wrapper lined up directly behind oneanother. The compartment conveyor chain ensures longitudinal grouping for packaging in 6-packs. The individual groups can now be wrapped in shrink film.The film is unwound and trimmed off by a servo-controlled cutter. The front edge of the film is then guided underneath the bottle group. A roller picksup the end by rolling over the pack and wrapping the film around it. The bottles are now ready for the shrink tunnel.

Shrink Tunnels
Everything needs to fit correctly: the bottles previously wrapped in shrink film are transported into the shrink tunnel.Under controlled and constant heat, the film shrinks to tightly fit the bottles. In the delivery area, the bundles created then cool down and are readyfor palletizing.

Palletizers
A parallelogram-type robot with reinforced base construction and sufficient arm length assumes responsibility for loading the pallet. The motion profilesof the robot kinematics can be calculated as axis movements and controlled using Lenze Controller-Based Automation with predefined profiles. Thesemovements are synchronized with the conveyor belt.

Lenze Drive Repair

Precision Electric offers Lenze drive repair because manufacturers cannot afford downtime when equipment fails. Most Lenze drives are replaceable but Lenze drives that aren’t in stock have extensive lead times. Lenze drive repair is usually less expensive than Lenze drive replacement.Precision Electric offers free Lenze drive repair quotes to customers who have failed Lenze equipment. The following is a list of steps Precision Electric uses for each Lenze drive repair.

Checking connections is a step many people miss or do incorrectly during Lenze drive repair. Heat cycles and mechanical vibration can lead to substandard connections, as can standard preventative maintenance practices. Reusing torque screws is not a good idea, and further tightening an already tight connection, can ruin the connection. Bad connections eventually lead to arcing. Arcing at the drive input terminal can result in nuisance over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the drive output terminal could result in over-current faults or even damage to the power components. Loose connections can cause erratic operation. For example, a loose START/STOP signal wire can cause uncontrollable drive starting and stopping. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, or personnel injury.

Conduct Diode and IGBT Tests – There are a number of methods to test the input and output power sections during Lenze drive repair, and this step is essential prior to applying power to the drive unit. If for any reason there is a short on the input side or output side of the drive, further damage can be caused to the unit if power is applied to it. For this reason, Precision Electric uses meters to properly test the input and output power sections of the drive prior to applying power to the actual unit. If a short is found, the unit can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the repair is too costly, then a replacement is offered to the customer.

Power Up Unit – Before powering up the Lenze drive, programs and parametersthat can be salvaged from the drive should be backed up to a separate drive or computer. Then, if the input and output power sections test healthy during the Lenze drive repair, power is applied to the unit to perform amp reading and output frequency tests. Precision Electric prefers to slowly increase power voltage to the drive until the rated input voltage of the drive is achieved. Depending on whether or not the Lenze drive provides a display will determine what further action(s) will be taken. If display is unavailable, disassembly and diagnosis of the internal power supply of the control section of the drive is likely necessary to further evaluate cause of failure and establish cost and lead time for the repair.

Run A Motor – If the previous tests have passed during the Lenze drive repair process, then it is time to run a basic jog function of the drive with a simple template program. After the drive programs and parameters are backed up and saved, we either reset the adjustable speed drive to factory defaults and recommission a basic start, stop and job application or closed loop if an encoder is involved. If the motor will not run, it will be necessary to check the output voltages and current ratings going to the motor to see if the drive is functioning properly to rotate the motor.

Contact Customer – At this point we have determined the cause of failure, estimated lead time and cost of the parts that need replaced for the Lenze drive repair, and are ready to offer the customer our repair quote. If the drive performs perfectly during the entire repair process, then further underlying issues are communicated with the customer. This is when Precision Electric will gather application specific information from the customer to establish whether or not it may be some outside issue associated with the system; such as PLC communications, faulty I/O, bad wiring, bad cabling. There is no single way to do this step since it depends on a wide variety of variables.

Lenze drive repair should be taken with extreme caution. Drive repair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends consulting an expert in the field when repairing all industrial electrical equipment. Many drive controllers have an internal DC bus that retains a charge after power has been cut to the drive, as a result, it does not mean it’s safe to work with. Technicians working variable frequency drives and other electrical equipment must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.

Eaton Drives Troubleshooting

Eaton drivestroubleshooting can be time consuming, so manufacturers tend to keep spare Eaton drives on hand for production lines that can’t afford downtime.When Eaton drivestroubleshooting cannot be resolved in the plant, technicians are known to send their Eaton VFD to the original equipment manufacturer or Eaton VFD repair centers for repair and replacement options. The original equipment manufacturer of Eaton drives and Eaton VFD repair centers usually only offer a replacement for failed drives, but this isn’t usually the most economical solution for manufacturers. Eaton also repairs failed drives but the lead-time for Eaton to repair their own drives is extensive and expensive.

When Eaton drivestroubleshooting leads to Eaton VFD repair, the repair process should be taken with extreme caution. Eaton VFD repair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing and troubleshooting Eaton VFD equipment.The troubleshooting techniques for each brand of VFD can be unique, but the overall structure of troubleshooting always remains the same.The ultimate goal when performing Eaton drivestroubleshooting is to diagnose, repair and re-commission the unit as quickly as possible, and these are the steps that Precision Electric follows for Eaton drive repairs.

Take Notes

This is often a subject that is passed by many individuals who are attempting to troubleshoot industrial electrical equipment.

When Eaton drivesTroubleshooting exceeds parameter changes, Precision Electric tests the input and output power sections of the Eaton VFD. This step is essential prior to applying power to the VFD unit. If for any reason there is a short on the input side or output side of the VFD, further damage can be caused to the unit if power is applied to it.

For this reason, Precision Electric uses meters to properly test the input and output power sections of the Eaton VFD prior to applying power to the actual unit. If a short is found, the unit can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the repair is too costly, then a replacement is offered to the customer.

Power Up

If the input and output power sections test healthy during this step of the Eaton drivestroubleshooting and repair process, Precision Electric will power up the unit and perform amp reading and output frequency tests. Precision Electric prefers to slowly increase power voltage to the unit until the rated input voltage of the VFD is achieved.

Depending on whether or not the VFD provides a display will determine what further action(s) will be taken. If display is unavailable, dis-assembly and diagnosis of the internal power supply of the control section of the VFD is likely necessary to further evaluate cause of failure and establish cost and lead time for the Eaton VFD repair.

Run A Motor

If the previous three tests have passed during the Eaton drives troubleshooting and repair process, then it is time to run a basic jog function of the VFD with a simple template program. Often when a VFD comes into our facility, we make sure to backup whatever program is currently stored in the VFD prior to inputting a template program and running a test procedure. This is to ensure we have a backup copy of the program.

The best method for backing up depends on the brand of drive, but after it has been backed up, we either reset the Eaton VFD to factory defaults through the keypad and recommission a basic start, stop and job application or closed loop if an encoder is involved. If the motor will not run, it will be necessary to check the output voltages and current ratings going to the motor to see if the VFD is functioning properly to rotate the motor.

Contact Customer

At this point we have determined the cause of failure, estimated lead time and cost of the Eaton drivestroubleshooting and VFD repair. If the VFD has tested good entirely, then further underlying issues are communicated with the customer. This is when Precision Electricwill gather application specific information from the customer to establish whether or not it may be some outside issue associated with the system including, but not limited to, PLC communications, faulty IO, bad wiring or even bad cabling. There is no single way to do this step, as it depends on a wide variety of variables.

Send Service Tech

If the customer cannot establish failure on any other aspect of the machine and the Eaton drivestroubleshooting tests appear to be good, then it may be necessary to send a Precision Electric field service technician on site to establish cause of failure. Precision Electricfield service technicians are trained to troubleshoot any issue ranging from standard VFD repair to advanced robotics, servo systems, electric motor issues and more. Precision Electric field technicians are trained to establish cause of failure and come up with solutions as quick as possible.

Adjustable Speed Drive Repair

Checking connections is a step many people miss or do incorrectly during anadjustable speed drive repair process. Heat cycles and mechanical vibration can lead to sub-standard connections, as can standard preventative maintenance practices. Reusing torque screws is not a good Idea, and further tightening an already tight connection, can ruin the connection. Bad connections eventually lead to arcing. Arcing at the drive input terminal can result in nuisance over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the drive output terminal could result in over-current faults or even damage to the power components.Loose connections can cause erratic operation. For example, a loose START/STOP signal wire can cause uncontrollable drive starting and stopping. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, or personnel injury.

At this point we have determined the cause of failure, estimated lead time and cost of the adjustable speed drive parts that need replaced, and are ready to offer the customer our repair quote. If the adjustable speed drive has tested good entirely, then further underlying issues are communicated with the customer. This is when Precision Electric will gather application specific information from the customer to establish whether or not it may be some outside issue associated with the system including, but not limited to, PLC communications, faulty I/O, bad wiring or even bad cabling. There is no single way to do this step since it depends on a wide variety of variables.

Routine Maintenance
Most adjustable speed drive repair can be prevented with routine maintenance. Adjustable speed drive repair cost and lead times can also be reduced with routine maintenance. Adjustable speed drive repair can be expensive and also cost manufacturers production downtime during the repair process. Most manufacturers keep spare drives in stock to prevent production downtime when their adjustable speed drive repair is in process.

Adjustable speed drive repair should be taken with extreme caution. Adjustable speed drive repair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing all industrial electrical equipment. Many drive controllers have an internal DC bus that retains a charge after power has been cut to the drive, as a result, it does not mean it’s safe to work with. Technicians working with drive repair must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.
