Detailed Function Description
59
Notice:
z When running at torque control mode, the acceleration time has nothing to
do with P0.11.
z 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.
