Overcurrent
during
acceleration
E 02.00
Ground fault or
short circuit exists in
the output circuit.
Check whether short-circuit occurs on the
motor, motor cable, or contactor.
The control mode
is SVC or FVC but
motor auto-tuning is
not performed.
Set motor parameters according to motor
nameplate and perform motor auto-tuning.
Acceleration time is
too short.
Increase acceleration time.
The overcurrent
stall prevention
parameters are set
improperly.
Ensure that current limit is enabled (F3-19 = 1).
The setting of F3-18 (Current limit level) is too
large. Adjust it between 120% and 160%.
The setting of F3-20 (Current limit gain) is too
small. Adjust it between 20 and 40.
Customized torque
boost or V/F curve is
not appropriate.
Adjust the customized torque boost or V/F
curve.
The spinning motor
is started.
Enable the catching a spinning motor function
or start the motor after it stops.
The drive
suffers external
interference.
View historical fault records. If the current
value is far from the overcurrent level, find the
interference source. If an external interference
does not exist, the drive board or hall device
may be faulty.
