Too loud motor noise
Increase the setting of P0-15 (carrier frequency) by 1.0 kHz
gradually. Note that increase in carrier frequency will result
in an increase in the
leakage current of the motor.
Insufficient motor
torque
Check whether torque upper limit is small. If yes, please
Increase the setting of P2-10 (digital setting of torque upper
limit in speed control mode) in the speed control mode;
Increase the torque reference in the torque control mode.

Drive in Feedback Vector Control (P0-01 = 1)
It is applicable to the application with an encoder for speed feedback. In this mode, you need
to set the encoder pulses per revolution, the encoder type and the encoder direction correctly.
ERROR
Solution
Overload or
over current fault
detected during motor
start
Set P1-27, P1-28 and P1-30 correctly.
Over load or
over current detected
during motor running
Set motor parameters p1-01 to P1-05 according to the
motor
nameplate.
Select a proper motor auto-tuning mode by setting P1-37
and perform
motor auto-tuning. If possible, select dynamic
auto-tuning
Poor torque or speed
response and motor
oscillation at speeds
below 5 Hz
If motor torque and speed response are too slow, increase the
setting
of
P
2-00 (speed loop proportional gain 1) by 10
gradually or decrease
the setting of
P
2-01 (speed loop
integral time 1) by 0.05 graduall
y
If motor oscillation occurs, decrease the setting of P2-00
and
P
2-01.
Poor torque or speed
response and motor
oscillation at speeds
above 5 Hz
If motor torque and speed response are too slow, increase the
setting
of P2-03 (speed loop proportional gain 2) by 10
gradually or decrease
the setting of P2-04 (speed loop
integral time 4) by 0.05 gradually.
If motor oscillation occurs, decrease the setting of P2-03 and
P2-04.
Obvious speed
fluctuation
If motor speed fluctuation is large, increase the setting of P2-
07 (SVC

lter time) by 0.001s gradually.
Too loud motor noise
Increase the setting of P0-15 (carrier frequency) by1.0 kHz
gradually. Note that increase in carrier frequency will result
in an increase in the
leakage current of the motor.
Insufficient motor
torque
Check whether torque upper limit is small. If yes, please:
Increase the setting of P2-10 (digital setting of torque upper
limit in
speed control mode in the speed control mode.

Drive in V/F Control (P0-01=2 factory default)
It is applicable to application without an encoder for speed feedback. You need to set rated
Motor voltage and rated motor frequency correctly.
