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]". Thus, first this motor control type must be configured. For details see chapter "Sensorless vector control (SLVC)".
After configuration, one of the following optimisations
must be carried out for torque control that is as precise as possible:
Automatic motor identification (energized)
