Descriptions
1
ocA
oc at Accel
Fault
Over-current during acceleration
(output current exceeds three times the drive’s rated current during
acceleration).
corrective action
1. Short-circuit at motor output: Check for possible poor
insulation at the output.
2. Acceleration Time is too short: Increase the Acceleration
Time.
3. AC motor drive output power is too small: Replace the AC
motor drive with a higher power model.
2
ocd
oc at Decel
Fault
Over-current during deceleration
(output current exceeds three times the drive’s rated current during
deceleration).
corrective action
1. Short-circuit at motor output: Check for possible poor
insulation at the output.
2. Deceleration Time is too short: Increase the Deceleration
Time.
3. AC motor drive output power is too small: Replace the AC
motor drive with a higher power model.
3
ocn
oc at Normal SPD
Fault
Over-current during steady operation
(output current exceeds three times the drive’s rated current during
constant speed).
corrective action
1. Short-circuit at motor output: Check for possible poor
insulation at the output.
2. Sudden increase in motor load: Check for possible motor stall.
3. AC motor drive output power is too small: Replace the AC
motor drive with a higher power model.
4
GFF
Ground Fault
Fault
Ground fault
When one or more of the output terminals is (are) grounded, and
the short circuit current is more than 60% of the AC motor drive
rated current, the AC motor drive power module may be damaged.
NOTE:
The short circuit protection is to protect the AC motor
drive, not to protect you.
corrective action
1. Check the wiring connections between the AC motor drive and
motor for possible short circuits, also check connection to
ground.
2. Check whether the IGBT power module is damaged.
3. Check for possible poor insulation at the output.
