The automatic restart function can be used for the following faults. Please note that when the fault is not listed in
the table the inverter will not attempt an automatic restart.
OC-S
Over current at start
OV-C
Over voltage during operation / deceleration
PF
Input phase loss
OC
Over current
OL1
Motor overload
OL2
Motor overload
OL3
Over Torque
LV
Low voltage during operation
OVSP
Over Speed
LIFE 1
Maintenance required input surge protection circuit
LIFE 2
Maintenance required control Circuit main capacitors
LIFE 3
Maintenance required DC-bus capacitors
Note: Auto restart after a fault will not function during DC injection braking or decelerating to stop.

Trip Prevention Level During Acceleration
Range
【
50 ~ 200
】
%
Trip prevention adjustment level during acceleration to prevent over current (OC-A) trips.
If trip prevention during acceleration is enabled and an over current condition occurs due to a heavy load, the
acceleration is put on hold until the output current drops below the setting of parameter 08-01 after which
acceleration resumes.

Trip Prevention Level During Deceleration
Range
【
50 ~ 200
】
%
Trip prevention adjustment level during deceleration to prevent over Voltage (OV-C) trips.
If trip prevention during deceleration is enabled and an over voltage condition occurs during stopping due to the
load (regenerative energy), deceleration is put on hold until the output current level falls below the setting of
parameter 08-02 after which deceleration resumes.

Trip Prevention Level During Continuous Run Mode
Range
【
50 ~ 200
】
%
Trip prevention adjustment level during continuous Run to prevent over current (OC-C) trips.
If trip prevention during continuous Run is enabled and an over current occurs due the load such as a sudden
transient load, the output frequency is reduced by decelerating to a lower speed until the over current level falls
