8 Conguring the torque control
In general, the inverter is operated in a mode that controls the motor frequency. Alternavely,
the inverter can be congured in such a way that it controls a motor torque within a dened
frequency range.
Typical applicaons for such a torque control with frequency limitaon are winders and pack-
aging machines.
Precondions
A torque control is only possible in the motor control type 0x2C00 (P300.00) = "Sensorless
vector control (SLVC) [4]" or "Servo control (SC ASM) [2]". Thus, rst this motor control type
must be congured. For details see the following chapter:
4Sensorless vector control (SLVC) ^ 174
4Servo control for asynchronous motor (SC-ASM) ^ 169
Aer conguraon of the motor control type, one of the following opmisaons must be car-
ried out for a torque control that is as precise as possible:
4Automac motor idencaon (energized) ^ 216
4Automac motor calibraon (non-energized) ^ 218
