Torque control without encoder:
This control structure corresponds to that of speed control without encoder, whereby
the speed controller is overdriven by the main demand preset. The additional demand
controls the limits of the speed controller and therefore the load current demand (the
rotor current control value) which in the constant flux range is proportional to torque.
The parameters of the current limiter function determine the load current adjustment
range.

Speed control Kp
Parameter for adjusting the P gain of the speed controller.
Range: 0 ... 100 000
As supplied: 10
Speed Controller Tn
Parameter for adjusting the speed controller recovery time.
Range: 0 ... 10 000 s
As supplied: 80 ms
Or controller Kp
1)
Parameter for setting the P gain of the flux orientation control. This parameter is set
automatically according to the motor data entered but can be overwritten if required.
A change on the “Type data” menu will initialise the parameter, i.e. the values entered
are replaced.
Range: 0 ... 100 000
As supplied: (Calculated according to the type data)
1)
Only accessible on protection level 1 and above.
