torque
2） 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.

3）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.

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.

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.

Set P1-27, P1-28 and P1-30 correctly.

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

If motor torque and speed response are too slow, increase the
setting of P2-00 (speed loop proportional gain 1) by 10
gradually or decrease the setting of P2-01 (speed loop
integral time 1) by 0.05 gradually

If motor oscillation occurs, decrease the setting of P2-00
and P2-01.

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.
 If motor speed fluctuation is large, increase the setting of P2-
07 (SVC torque filter time) by 0.001s gradually.

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.

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.
