Setting range of P03.02: 0.00Hz – P00.05
Setting range of P03.05: P03.02 – P00.03
0 – 8 (corresponds to 0 – 2
Slip compensation coefficient is used to adjust
the slip frequency of the vector control and
improve the speed control accuracy of the
system. Adjusting the parameter properly can
control the speed steady-state error.
Setting range: 50% – 200%
Note:
These two parameters adjust the PI adjustment
parameter of the current loop which affects the
dynamic response speed and control accuracy
directly. Generally, users do not need to change
the default value;
Only apply to the vector control mode without PG
0 (P00.00=0).
Setting range: 0 – 65535
This parameter is used to enable the torque
control mode, and set the torque setting means.
0: Torque control is invalid
1: Set via keypad（P3.12）
2: Set via AI1 (100% relative to three times of
motor current)
3: Set via AI2 (100% relative to three times of
motor) (same as above)
4: Set via AI3 (100% relative to three times of
motor) (same as above)
5: Set via pulse frequency HDI (same as above)
6: Multi-step torque setting (same as above)
7: Set via MODBUS communication
