Our Team Expertly Repairs Yaskawa AC Inverter Drive CIMR-P5 series

Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC inverters such as Yaskawa CIMR-P5 Series inverter.

The P5 drive is a full featured drive providing outstanding quality, performance, and flexibility through 300kW. This drive combines easy to use network communications, feedback, and expandable I/O to control anything from simple fans and pumps to complex machines. The P5 inverter is a single solution regardless of your application. The P5 inverter is a great platform to start a retrofit from, ask us how we can help you with a retrofit.

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-P5 SERIES INVERTER 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.

Using your digital multimeter check the DC buss and make sure the DC buss has been discharged.

Input Modules Testing

Multimeter Positive Lead Negative Side of the DC Bus
Multimeter Negative Lead L1 L2 L3
Diode Check Approximately 0.41 V for each phase
Multimeter Positive Lead L1 L2 L3
Multimeter Negative Lead Positive Side of the DC Buss
Diode Check Approximately 0.42 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 0.38 V for each phase
Multimeter Positive Lead Negative Side of the DC Buss
Multimeter Negative Lead U V W
Diode Check Approximately 0.37 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 drive are displayed through digital operator located on the front of the inverter. The codes displayed are:

Alarm Code Code Type
GF Ground Fault
OC Over current
OL1 and OL2 Overload
RR Braking Transistor Shorted
ERR Control Board Hardware Failure
UV Undervoltage
OV Overvoltage
OH and OH2 Overheat
OS Overspeed detection
OPE Parameter Alarms
PF and PH Phase Loss or Open Phases

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