Inverter-General Purpose Yaskawa CIMR-PC3

Our Team Expertly Repairs Yaskawa AC Inverter CIMR-PC3 Series

Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC inverters such as Yaskawa CIMR- PC3 Series inverter.

Yaskawa’s CIMR- PC3 inverter is a tough, effective and adaptable inverter that is software based which offers flexibility to every machine application. A broad function selection allows rapid and significant changes in machine’s performance.

Alarm codes, parameters and monitor functions can be viewed through the digital operator on the front of the inverter or there can be an indication cover installed that replaces the operator after initial set up of the drive.

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-H3 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 0.43 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
OU	Overvoltage
OL1	Overload on Motor
OL2	Overload on Inverter
RR	Braking Transistor Failure
CPF	Control Circuit
oH	Heatsink Fans Overheat

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