Our Team Expertly Repairs Yaskawa AC Servo Drive CACR-SR_SB-BB1 Series
Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC Servo series such as Yaskawa CACR-SR_SB-BB1 Series Servopack.
The CACR-SB series being the through hole mounted version and CACR-BB1 being the base mounted version. The Yaskawa AC Servo Drive CACR-SR_SB-BB1 series 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 CACR-SR_SB-BB1 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 0.2-1.0 V |
| R S T | Positive Capacitor Terminal | Approximately 0.2-1.0 V |
Output Modules Testing
| Multimeter Positive Lead | Multimeter Negative Lead | Diode Check |
|---|---|---|
| Negative Capacitor Terminal | U V W | Approximately 0.2-1.0 V |
| U V W | Positive Capacitor Terminal | Approximately 0.2-1.0 V |
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
There is no seven segment display on these drives. All alarms are displayed through the control. There is an alarm LED on the front of the drive at will be on if there is an alarm. The codes displayed are:
| Alarm Code | Code Type | Alarm Type | Cause |
|---|---|---|---|
| A.3 | Regeneration Error Detected | Braking Circuitry Alarms | Regen circuit failure |
| A.4 | Overvoltage | Braking Circuitry Alarms | Regen circuit failure |
| 4 | Overvoltage | Power Alarm | Incoming voltage problerm |
| 6 | Undervoltage | Power Alarm | Incoming voltage problerm |
| F | Open Phase | Power Alarm | Incoming voltage problerm |
| 1 | Overcurrent | Motor Alarm | Low ground insulation |
| 5 | Overspeed | Motor Alarm | Faulty connections or incorrect parameters |
| J | Overflow | Motor Alarm | Faulty connections or incorrect parameters |
| 7 | Overload | Motor Alarm | Improper cooling, incorrect parameters, or motor overload |
| A | Heat Sink Overheat | Motor Alarm | Improper cooling, incorrect parameters, or motor overload |
| 0 | Absolute Error | Encoder Alarms | Incorrect data from encoder |
| 8 | Position Error | Encoder Alarms | Incorrect data from encoder |
| C | PG Disconnection | Encoder Alarms | Incorrect data from encoder |
| J | Overflow | Encoder Alarms | Incorrect data from encoder |
| L | Overrun | Encoder Alarms | Incorrect data from encoder |
Alarm Y.Pr - Indicates a parameter error which could occur if data has become corrupted or incorrect parameters were loaded. If reloading parameters doesn’t correct this issue there is likely a problem with the drive.
2 MCCB Trip - Can occur during shipping or if something has shorted out in the drive. So if you just received this drive please make sure the breaker is no tripped, or if it was running, find the source of the short before resetting this breaker.
The majority of these alarms can be triggered if there is a fault in the control circuit.
