Fault Name Fault Descriptions Corrective Actions
Auto accel / decel failure
Don‟t use the function of auto acceleration/
deceleration.
Ground fault :
The AC drive output is abnormal.
When the output terminal is
grounded (short circuit current is
50% more than the AC drive rated
current), the AC drive power
module may be damaged.
The short circuit protection is
provided for AC drive protection,
not user protection
Ground fault :
1. Check whether the IGBT power module is
damaged.
2. Check for possible poor insulation at the
output line.
Communication Error
Please refer to Pr.92.
1. Check the connection between the AC drive
and computer for loose wires.
2. Check if the communication protocol is
properly set.
External Base Block.
AC drive output is turned off.
1. When the external input terminal
(baseblock) is active, the AC drive output will
be turned off.
2. Disable this connection and the AC drive will
begin to work again.
OC hardware error
Return to the factory.
CC (current clamp)
OV hardware error
GFF hardware error
OV or LV
Current sensor error
U-phase error
Return to the factory.
W-phase error
Phase Loss Check input phase wiring for loose contacts.
Software protection failure Return to the factory.
PID feedback signal error
1. Check parameter settings (Pr.116) and
AVI/ACI wiring.
2. Check for possible fault between system
response time and the PID feedback signal
detection time (Pr.123)
