Inverter-General Purpose Yaskawa CIMR-V1000

Our Team Expertly Repairs Yaskawa AC Inverter CIMR-V1000 Series

Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC inverters such as Yaskawa CIMR- V1000 Series inverter.

The V1000 is a world-class compact current vector drive that defines a new world standard. Demands for efficient production and better maintainability are on the rise, spurred by global competition.

The Yaskawa promise of being in control with products that makes businesses move has happened with the V1000. The optimum balance of energy input, product output, maintenance risk, and long life is reached with Yaskawa. The V1000 provides a world of power in the palm of your hand!

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- V1000 SERIES INVERTER

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 0.2-1.0 V for each phase

Multimeter Positive Lead	L1 L2 L3
Multimeter Negative Lead	Positive Side of the DC Buss
Diode Check	Approximately 0.2-1.0 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 0.2-1.0 V for each phase

Multimeter Positive Lead	Negative Side of the DC Buss
Multimeter Negative Lead	U V W
Diode Check	Approximately 0.2-1.0 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
LF	Output Phase Loss
OC	Overcurrent
oH and oH 1	Heatsink Overheat
oLH3 and 4	Motor Overheat
OV	Overvoltage
PF	Input Phase Loss
CPF	Alarms are Control Board Faults

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