Series: ASDA-W3
Drive module (DM) interference or firmware incompatibility
servo drive
Meaning: 1. Firmware incompatibility. 2. Current loop timing error.
Possible causes
- Conditions:
- Firmware incompatibility.
- Current loop timing error. Cause:
- The firmware versions of the modules are incompatible. This alarm is displayed immediately after drive power-on.
- Drive module or backplane error. The drive module is continuously subjected to communication interference from the backplane, affecting current loop operation. This alarm is likely to occur during Servo On.
