Series: MD200, MD310
Overcurrent at constant speed
AC drive
Meaning: This fault is triggered at constant speed when the instantaneous output current exceeds 2.5×1.414 times the rated current of the AC drive.
Possible causes
- 1, Ground fault or short circuit in the AC drive output circuit
- 2, The control mode is SVC and auto-tuning has not been performed
- 3, Inappropriate overcurrent stall suppression setting
- 4, AC drive undersized
- 5, External interference
