Where d0-00 to d0-31 are the run and stop monitoring parameters defined in P7-03 and
P7-04.

Display PID set value and feedback value, the value format is as follows:
PID setting = PID setting (percentage) * PA-04
PID feedback = PID feedback (percentage) * PA-04

1） Drive in Open-loop Vector Control （P0-01=0）
The AC drive implements control of the motor speed and torque without an encoder for
speed feedback. In this control mode, motor auto-tuning is required to obtain the motor

 Set motor parameters （P1-01~P1-05） according to motor
nameplate.
 Select a proper motor auto-tuning mode by setting P1-37 and
perform motor auto-tuning. If possible, select dynamic auto-
tuning
 1. 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.
 2. If motor oscillation occurs, decrease the setting of P2-00
and P2-01.
 1. 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.
 2. If motor oscillation occurs, decrease the setting of P2-03
and P2-04.

If speed error when motor runs with load is large, increase
the setting of P2-06 (vector control slip compensation gain)
by 10% gradually.
 If motor speed fluctuation is large, increase the setting of P2-
07 (SVC torque filter time) by 0.001s gradually.
