vector and without
identification of
parameters
6.the motor that is
rotating is started
unexpectedly.
7.suddenly increase the
load in the process of
acceleration.
8.the type selection of
inverter is small
for the motor parameters
6.select Speed Tracking
Start or restart after
stopping the motor.
7.cancel the sudden load
8.choose the inverter
with large power level

Err.03
Deceleration
overcurrent
1.the short-circuit or
earthing of inverter
output happens
2.the control mode is
vector and without
identification of
parameters
3.the deceleration time is
too short
4.the voltage is low
5.suddenly increase the
load in the process of
deceleration.
6.didn't install braking
unit and braking resistor
1.eliminate peripheral
faults
2.perform identification
for the motor parameters
3.increase the
deceleration time
4.set the voltage to the
normal range
5.cancel the sudden load
6.install braking unit and
brake resistor
