Our Team Expertly Repairs Yaskawa AC Spindle Drive CIMR-VM3 series

Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC Spindle series such as Yaskawa CIMR-VM3 Series Spindle Drives

Varispeed 626 VM3 Drives are reliable adjustable speed A/C spindle motor drives. CIMR-VM3 drives combine a compact A/C spindle drive motor with a digital vector controlled, transistor inverter. Alarm information can be viewed and reset and parameters can be viewed and changed with a digital operator located on the front of the drive

The CIMR-VM3 drives achieve high speed operation and heavy duty machining even while operating under adverse environmental conditions. The CIMR-VM3 is an ideal spindle drive for machining centers, lathes, and milling machines.

When assessing the functionality of a drive, our engineering team typically conducts a four-step check:

  • Visual Overview Check
  • Static Test
  • Checks Under Power
  • Alarm Codes Verification

This overview is Precision Zone’s basic troubleshooting process. Once our repair team starts on the job we use specialized, customized test fixtures, Huntron tracker, signal generator, oscilloscope, milli and mega ohm meters and other necessary tools to assure quality repair. Most importantly, every repair is fully tested in custom-built simulators under load to replicate real-life working environment. Precision Zone goes as far as using heat chamber and overnight dynamic testing to guarantee performance of the repaired product when it comes back to the customer.

REPAIR PROCESS FOR CIMR-VM3 SERIES DRIVE

Visual Overview Check

When conducting a visual check, the technician inspects the drive for any mechanical damage to the drive and print circuit boards. Then the team proceeds to verify connections are tight and correct inside the drive and there are no loose screws, wires or particles. Additionally, we look for any burn marks anywhere on the components or chassis. During the visual inspection technical team notes excessive dirt on cooling components and records clogged heatsink.

Static Test Basic

Precision Zone repair technicians use digital multimeter with diode testing capabilities and resistance measurement to conduct a static test. In the instance of Diode testing, our team is looking to check input and output modules.

First you must open up the drive and using your digital multimeter check the DC buss and make sure the DC buss has been discharged.

Input Modules Testing

Multimeter Positive Lead L1 L2 L3
Multimeter Negative Lead Positive Side of the DC Buss
Diode Check Approximately 0.36 Volts for each phase
Multimeter Positive Lead Negative Side of the DC Buss
Multimeter Negative Lead L1 L2 L3
Diode Check Approximately 0.36 V for each phase

Output Modules Testing

Multimeter Positive Lead U V W
Multimeter Negative Lead Positive Side of the DC Buss
Diode Check Approximately 0.33 V for each phase
Multimeter Positive Lead Negative Side of the DC Buss
Multimeter Negative Lead U V W
Diode Check Approximately 0.32 V for each phase

We verify capacitor value using capacitor meter and examine functionality of circuit breakers and contactors in the drive.

Alarm Codes Troubleshooting

The alarms on the spindle drive are displayed through digital operator located on the front pannel. The codes displayed are:

Alarm Code Cause
F000 Winding selection failed
F100 Output Overcurrent
F300 Input Overcurrent
F201 MCCB Circuit Breaker Tripped
F602, 603, 604 Incoming Power Alarms
F700 and F701 Overload Alarms
F900 and 901 Motor Thermal Alarms
FA00 Initial Start Up Alarm

The majority of these alarms can be triggered if there is a fault in the control circuit.
