Drives-AC Servo Yaskawa CACR-SR BE1 | Repairs Precision Zone

Our Team Expertly Repairs Yaskawa AC Servo Drive CACR-SR BE1 Series

Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC Servo series such as Yaskawa CACR-SR BE1 Series Servopack.

Yaskawa AC Servo Drive CACR-SR BE1 has been developed as basic mechatronics drives for the most advanced Factory Automation and Factory Machining Systems, including robots and machine tools.

For your mechatronics systems, the flexible CACR-SR BE1 Series Servopack achieves stable control operation with high accuracy, quick response control under any environmental condition, and smooth, powerful operation even at low-speed range.

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 CACR-SR BE1 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	Multimeter Negative Lead	Diode Check
Negative Capacitor Terminal	R S T	Approximately 0.43 V
R S T	Positive Capacitor Terminal	Approximately 0.43 V for each phase

Output Modules Testing

Multimeter Positive Lead	Multimeter Negative Lead	Diode Check
Negative Capacitor Terminal	U V W	Approximately 0.43 V for each phase
U V W	Positive Capacitor Terminal	Approximately 0.43 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 servopack are displayed through a seven segment LED display located on the control board. The codes displayed are:

Soft Alarms

Alarm Code	Code Type	Cause
A.02	Parameter Breakdown	Incorrect parameters or corrupted data
A.04	Parameter Setting Error	Incorrect parameters or corrupted data

Control Circuit Failures

Alarm Code	Code Type	Cause
A.03	Main Circuit Detection Error	Problem with the control circuit

Braking Alarms

Alarm Code	Code Type	Cause
A.30	Regeneration Error Detected	Regen circuit failure or faulty regen resistor
A.40	Regeneration Error Detected	Regen circuit failure or faulty regen resistor

Power Alarms

Alarm Code	Code Type	Cause
A.40	Overvoltage	Problem with incoming voltage
A.60	Undervoltage	Problem with incoming voltage
A.F1	Open Phase	Problem with incoming voltage
A.F2	Power Supply Rise Error	Problem with incoming voltage

The majority of these alarms can be triggered if there is a fault in the control circuit, so please keep that in mind.
