CHV100 Series Close Loop Vector Control Inverter
.64.
l
Torque control can be switched to speed control, vice versa.
n
Switching by multifunctional terminal: For example, if torque setting source is
AI1 (P3.12=2), the value of multifunction terminal S5 is set to 31 (Disable
torque control). When S5 is valid, control mode will switch from torque
control to speed control, vice versa.
n
When running at torque control mode, press STOP/RST, it will switch to
speed control automatically.
l
If torque setting is positive, inverter will run forward; otherwise it will run reverse.
Notice:
l
When running at torque control mode, the acceleration time has nothing to
do with P0.11.
l
The 100% of torque setting is corresponding to 100% of P3.14 (Torque limit).
For example, if torque setting source is keypad (P3.12=1), P3.13=80% and
P3.14=90%, then
Actual torque setting = 80% (P3.13) * 90% (P3.14) = 72%.

0: Linear curve. It is applicable for normal constant torque load.
1: User-defined curve. It can be defined through setting (P4.03~P4.08).
2~4: Torque_stepdown curve. It is applicable for variable torque load, such as blower,
pump and so on. Please refer to following figure.
