VFD Repairs

VFD repairs should beginwith checking the electric motor connections and VFD terminals. Motor and VFD connections can be missed, installed loosely or wired to the incorrect terminals, so checking all connections is recommended before pulling the VFD for a repair evaluation. Heat cycles and mechanical vibration can lead to sub-standard connections. 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 over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the VFD input or output terminals may result in over-current faults or damage to the power components. Loose connections can cause erratic operation. For example, a loose START/STOP signal wire can cause uncontrollable starting and stopping of the motor. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, and personnel injury.

 

Diode and IGBT Testing

Prior to applying power during the VFD repairs, the input and output power sections need to be tested. If 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, special meters should be used to properly test the input and output power sections of the drive prior to applying power to the VFD unit. If a short is found, the VFD can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the VFD repairs are too costly, VFD replacement should be considered.

 

Power Up

If the input and output power sections test healthy during the VFD repairs process, power can be applied to the VFD unit to perform amp reading and output frequency testing. Slowly increasing the power voltage during this step of the VFD repairs process is suggested to gather accurate meter readings and to protect the motor. The power voltage is slowly increased on the VFD until the rated input voltage of the drive is reached. Depending on whether or not the VFD provides a display will determine what further action will be taken. If display is unavailable, disassemble 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 of the VFD repairs.

 

Motor Testing

If the previous three tests have passed during the VFD repairs process, a basic JOG/ RUN function of the drive can be performed with a simple template program. When a VFD comes into our facility, repair techs will backup all existing programs stored in the drive prior to installing a test template program for testing. Backing up the VFD program ensures that we have a backup copy of the program to install after the repair is complete. The best method for backing up VFD programs will depend on the series and model of drive that’s being repaired. After the VFD programs have been backed up, the VFD is reset to factory default through the keypad and then recommissioned to a basic START / STOP function of the VFD connected to its motor. Closed loop testing will be necessary when an encoder or tachometer is involved. If the motor will not run, the output voltages and motor current ratings are tested to verify that the drive is functioning properly to rotate the motor.

 

Routine Maintenance

VFD repairs should only be performed by trained technical staff during regular routine maintenanceor at a certified repairs facility.Routine maintenance prevents excessive VFD failure and production loss due to machinery downtime. VFD repairs are costly and lead times can also be extensive; and with regular routine maintenance, cost and lead times diminish. VFD repairs can be expensive depending on board and component damages. Most manufacturers keep spare VFD units in stock to prevent production downtime while the VFD repairs are being processed.

 

Safety Precautions

Manufacturers are encouraged to ensure that their VFD repairs are being performed at the actual site of whoever is offering the service. VFD repairs should be taken with extremecaution 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, and as a result, electrical current is still present afterpower is shut down. Technicians performing VFD repairs must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.

Precision Electric receives VFD repairs everyday from companies who offer VFD repairs; those third party repair companies will have Precision Electricperform the repair, and then they will mark up the repair cost to their customers. Going straight to Precision Electric for VFD repairs will prevent these added costs and prevent extensive lead times.For VFD repairs and VFD replacements, contact Precision Electric.

 

 

Siemens VFD Troubleshooting

Siemens VFD troubleshooting starts with checking the electric motor and VFD terminal connections. Motor and VFD connections can be overlooked, loose, or, wired to the incorrect terminals; so, checking all connections is suggestedbefore pulling the VFD and sending it in for a repair evaluation.

Heat cycles and mechanical vibration can lead to sub-standard connections. 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 that may clear input fuses, or damage protective components. Arcing at the VFD input or output terminals may result in over-current faults or damage to the power components. Loose connections can cause erratic operation. For example, a loose START/STOP signal wire to the drive can cause uncontrollablestarting and stopping. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, and personnel injury.

Siemens VFD Troubleshooting Diode and IGBT

If a short is found, the VFD can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the Siemens VFD repair is too costly, VFD replacement and availability is considered.

Siemens VFD Troubleshooting and Power Up

When a Siemens VFD comes into our facility, repair techs will backup all existing programs stored in the drive prior to installing a test template program for this test run procedure. Backing up the Siemens VFD program ensures availability of the program for installation, once the repair is complete. The best method for backing up Siemens VFD programs will depend on the series and model of drive.

If the motor will not run, the output voltages and motor current ratings are tested to verify that the drive is functioning properly for motor rotation.

Siemens VFD Troubleshooting and Routine Maintenance

Siemens VFD troubleshooting should be performed by trained electrical technicians during regular routine maintenance. Routine maintenance prevents Siemens VFD failure and production loss due to machinery downtime. Siemens VFD repair cost and lead times can also be reduced with routine maintenance. Siemens VFD repair can be expensive depending on board and component damage which ultimately will cost manufacturers production downtime during the repair process. Most manufacturers keep spare Siemens VFD units in stock to prevent production downtime during the Siemens VFD repair.

Siemens VFD Troubleshooting and Safety

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

Siemens VFD Troubleshooting and Repairs

Most companies who offer Siemens VFD troubleshooting and Siemens VFD repair do not even perform these services themselves. These companies outsource the repair to a third party certified VFD Repair Center, such as Precision Electric. Precision Electric receives Siemens VFD repair jobs everyday from companies who offer VFD repair. Those third party repair companies then mark up the repair cost to their customers. Manufacturers are encouraged to ensure that their Siemens VFD Repair is being performed at the actual site of whoever is offering the service.

Adjustable Frequency Drives

Adjustable frequency drives arealso known as adjustable speed drives, variable frequency drives, variable speed drives, VFDs andinverters.

Adjustable frequency drives are solid state electric motor control systems designed to control the speed of an electric motor. Adjustable frequency drives can reduce energy costsup to 50% by speed reduction on electric motorswhere the full speed of the electric motor is not needed. Drivefunctions allow an AC electric motor to only operate when neededwhich allows an electric motor to last longer.Technology has allowed adjustable frequency drives to reduce in cost and physical size and has improved performance through advances in semiconductor switching devices, simulation, control techniques, control hardware, and software.

Approximately one third of electrical energy in the world is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. These fixed-speed applications do not usually require full load speed of the electric motor theyre operating. By installing adjustable frequency drives to these applications, electric motor speeds are reduced and power costs can be reduced by 50% or more.Properly applied adjustable frequency drives withelectric motorswill significantly reduce energycosts for variable torque loads such as fans, blowers, and pumps.Blowers are often used with dampers to control air flow that operate either manually or automatically. When dampers are closed, 50% of the electric motor current will drop to approximately 60% of full load nameplate current. By utilizing adjustable frequency drivesin blower applications, the current draw of the motor will be reduced 30% for every 10% drop in speed. Electric motors controlled byadjustable frequency drives at 50% speed will draw approximately 20% of the electric motor full load current.

Adjustable frequency drives are also used on rotating equipment toreduce amperage spikes upon start up of large electric motors.Adjusting the acceleration and deceleration time of electric motors can extend the lifespan of an electric motor. Using a drive on an electric motor provides the ability to increase or decrease the frequent starting and stopping of an AC electric motor. Limiting the starting and stopping of a motor and controlling the ramp up and ramp down speed of amotor allows for decreased wear on an electric motor.Choosing the right drive for an application can helprotating equipment by providing less wear on the electric motors where applied.Adjustable frequency drivesare used in AC servo systems, air compressors, conveyor systems, lathes, mills, plastic extrusion, slitter lines, bottlers, packaging lines, pharmaceutical production, food processing, HVAC systems, waste water treatment systems, submersible pumps, fans, blowers, and many more electric motor applications.
