Configuring the torque control
In general, the inverter is operated in a mode that controls the motor frequency. Alternatively, the inverter can be configured in such a way that it controls a motor torque within a defined frequency range.
Typical applications for such a torque control with frequency limitation are winders and packaging machines.
Preconditions
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, first this motor control type must be configured. For details see the following chapter:
Sensorless vector control (SLVC)After configuration of the motor control type, one of the following optimisations
must be carried out for a torque control that is as precise as possible:
