Our Team Expertly Repairs Yaskawa AC Spindle Drive CIMR-MTIII series
Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC Spindle series such as Yaskawa CIMR-MTIII Series Spindle Drives.
Varispeed VS626 MTIII Drives are reliable adjustable speed A/C spindle motor drives. CIMR-MTIII drives combine a compact A/C spindle drive motor with a digital vector controlled, transistor inverter. There are five seven-segment leds that can display alarm information.
The CIMR-MTIII drives achieve high speed operation and heavy duty machining even while operating under adverse environmental conditions. The CIMR-MTIII is an ideal spindle drive for machining centers, lathes, and milling machines.
This series high-accuracy and quick response control even under adverse conditions, easy and flexible operation is available with excellent maintainability due to various display functions and protective functions.
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-MTIII SERIES SPINDLE 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.
You are not able to check the inputs on this drive.
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.
The last step in a static test process is checking the Regen Resistor. The technicians measure the resistance between Y3 and Y4. Resistance output results will vary depending on the size of the drive, but should not be shorted.
Alarm Codes Troubleshooting
The alarms on the spindle drive are displayed through five seven-segment display located on the control board. The codes displayed are:
Alarm Code | Code Type |
---|---|
ICP ICAN ICA1 AD ADC CPF PGC | Control Board Failures |
OHF | Controller Overheat |
NCC | Circuit Breaker |
10C | Overcurrent |
dEV | Deviation |
OL | Overload |
OS | Overspeed |
OV | Overvoltage |
UV | Undervoltage |
OH | Overheat |
FU | Fuse |
The majority of these alarms can be triggered if there is a fault in the control circuit.
