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:

Checkingconnections is a step many people miss or do incorrectly during the SVX9000 VFD repair process. Heat cycles and mechanical vibration can lead to sub-standard connections, as can standard preventative maintenancepractices. 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 VFD input could result in nuisance over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the VFD output 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 VFD 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 of aVFD, and 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 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 offeredto the customer.

Power Up Unit
If the input and output power sections test healthy during this step of the SVX9000 VFD repair process, Precision Electric will power 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 costand lead time for the VFD repair.

Run A Motor
If the previous three tests have passed during the SVX9000 VFD 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 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 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 checkthe 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 costof the SVX9000VFD 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 really 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 VFD appears to test fine, then it may be necessary to send a field service technician on site to establish cause of failure. Field service technicians should betrained to troubleshoot any issue ranging from standard SVX9000 VFD repair, to advanced robotics, PLCs and more. Field technicians should also be trained to establish cause of failure and come up with solutions as quick as possible.

SVX9000 VFD repair should be taken with extreme caution. SVX9000 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 VFD equipment.Many VFD 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 who perform SVX9000VFD repair must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur. All SVX9000 VFD repair performed by Precision Electric includes a 12 month warranty.

Plastic Processing Machinery

Plastic injection molding is a manufacturing process for producing parts by injecting material into a mold. Plastic processing machinery and plastic extrusion machinery are used in plastic injection molding industries. After100 years of development, plastic extrusion has gonefrom single screw to twin-screw, multiple screw (or no screw) to other more advanced processes. Plastic processing machinery requires versatility and precision. Through customized solutions, ABB plastic processing machinery is offered in a complete range of packages that include AC and DC motors, drives, controls and engineered safety features.


Specific AC and DC motor and drive solutions can be applied dependent on the type of end plastic product being produced as well as the type and size of the extruder. Motor types typically used include AC induction (enclosed or laminated frame designs), DC, servo or permanent magnet. Variable speed drives are used for precise motor control and increased energy efficiency, as well as for environmental and cost reasons. Drives also provide dynamic torque limit for protection of the extrusion screw without speed or position feedback devices, resulting in lower initial investment and installation costs and higher operational reliability. Downstream machinery: Various types of downstream machinery may be present to facilitate necessary cooling, take-off and/ or other discrete handling of the extruded material, such as cut-to-length, slitting, stacking, coiling, etc. These are in general typical drive applications requiring drive performance characteristics ranging from speed or torque regulation to simple motor control.

Processes Of Equipment

Amelt pump is fed by a speed-regulated, pressure-controlled extruder which provides precise control of the molten plastic output flow, optimizing the consistency of the flow delivery rate. Precise tension control is vital for plastic film processing. The superior speed regulation of ABB drives maintains the tension within the established limits and the fast, accurate drive-to-drive line speed communication provides precise synchronization of take-off roll sets.Film must be wound under constant tension, requiring torque regulation of the winder motor, which must continually adapt to ever-changing roll diameters. This can be achieved either by using an ABB drive with winder software or integrating a separate PLC into the control system.

ABBs dynamic control of asynchronous and PM servo motors enables the rapid correction of load-side disturbances. ABB drives with direct torque control (DTC) provide speed and torque control without sensors.ABB plastic processing offers a full complement of products and technologies for design and delivery of solutions tailored to meet individual needs and optimize investment returns.

ABB plastic processing machinery is designed by vast global experience gained from many decades of implementing motors, drives, controls and complete systems across a wide variety of extrusion types including: sheet extrusion, film extrusion, blown film, coating, tube/hose/pipe, co-extrusion and compound extrusion.
