Our Team Expertly Repairs Yaskawa DC Servo Drive CPCR-MRxxK series

Precision Zone specializes in Yaskawa product repairs servicing a wide range of DC Servo series such as Yaskawa CPCR-MRxxK Series Servopack.

Yaskawa AC Servo Drive CPCR-MRxxK was developed for the most advanced Factory Automation and Factory Machining Systems. The extensive servo manufacturing technology accumulated through half a century of servo drive applications created this series.

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 CPCR-MRxxK SERIES SERVOPACKS

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.

Input Modules Testing

Multimeter Positive Lead L1
Multimeter Negative Lead Positive Side DC Buss
Diode Check Approximately 0.3-0.4 V
Multimeter Positive Lead Negative Side DC Buss
Multimeter Negative Lead L1
Diode Check 0 L Displayed

Output Modules Testing

Multimeter Positive Lead B
Multimeter Negative Lead Positive Side DC Buss
Diode Check Approximately 0.3-0.4 V
Multimeter Positive Lead Negative Side DC Buss
Multimeter Negative Lead B
Diode Check Approximately 0.3-0.4 V

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 servopack are displayed through a five LED’s display located on the control board. Abbreviations are on the control board right next to the led. The codes displayed are :

Alarm Code Code Type Cause
A.FUSE Power Alarm Fuse
A.OV Power Alarm Overvoltage
A.OC Motor Alarm Overcurrent
A.TG Motor Alarm Tachometer problem
A.OL Motor Alarm Overload problem

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