Chapter 14 Error Codes

Over-current during acceleration (Output current exceeds triple rated current
during acceleration.)
Corrective Actions
 Short-circuit at motor output: Check for possible poor insulation at the
output.
 Acceleration time too short: Increase acceleration time.
 AC motor drive output power is too small: Replace the AC motor drive
with higher power model.
Over-current during deceleration (Output current exceeds triple rated current
during deceleration.)
Corrective Actions
 Short-circuit at motor output: Check for possible poor insulation at the
output.
 Acceleration time too short: Increase acceleration time.
 AC motor drive output power is too small: Replace the AC motor drive
with higher power model.
Over-current during steady state operation (Output current exceeds triple
rated current during constant speed.)
Corrective Actions
 Short-circuit at motor output: Check for possible poor insulation at the
output.
 Acceleration time too short: Increase acceleration time.
 AC motor drive output power is too small: Replace the AC motor drive
with higher power model.
