Yaskawa Error Code A910 Exclusive <TRUSTED>
0910
The Yaskawa error code (often displayed as A.910 ) typically indicates a CPU Error . This specific alarm is common on FS100 robot controllers , referring to a failure in the unit. Understanding Alarm 0910
Step-by-Step Exclusive Troubleshooting (Do Not Skip)
DC Bus / Rectifier Issues
- Set A1-04 = 0 (Disable password).
- Set o2-01 (LCD contrast) to any different value, then back to original. This forces a soft reset of the operator driver.
- Perform a 2-LEVEL initialization (A1-03 = 2220 or 3330 depending on drive series). Warning: This erases motor parameters. Backup first.
- The Drive's Logic: The IGBTs are switching. A voltage sag happens. The drive cannot maintain torque control. It immediately faults to protect the transistors from overcurrent due to insufficient voltage.
- The "Exclusive" Nuance: On some Yaskawa drives (especially GA800), A910 will trigger before a hardware damage fault like
UV1. It acts as a "soft" fault to ride through minor sags, but if the sag persists, it escalates.
