7) Torque Current reference
The torque reference is converted to the torque current reference. The torque current reference is generated from the
rated current and magnetizing current of the motor. The initial value of the rated current and magnetizing current of
the motor can be set by OTIS vector motor parameter that is chosen at PAR_07
Code LCD display Description Setting range Unit Factory setting
PAR_07 Motor Select Motor capacity selection 2.2 ~ 375.0 kW
PAR_22 Rated-Curr Motor rated current 1.0 ~ 2000.0 A
PAR_27 Flux-Curr Motor flux current 0.0 ~ 70% of PAR_22 A
8) Torque limit by Speed limit
This function limits torque when the speed reaches a certain level duing operation in torque mode. The torque
