Field weakening limit
(Field weakening limit)
S P
0 ... 110 %
{ 100 }
The field weakening limit determines at which speed / current the controller will begin to weaken
the field. At a set value of 100% the controller will begin to weaken the field at approximately the
synchronous speed.
If values much larger than the standard values have been set in P314 and/or P317, then the field
weakening limit should be correspondingly reduced, so that the control range is actually available
to the current controller.

{ 0 }
During the brake release time (P107/P114), the I component of the speed control is increased.
This leads to better load take-up, especially with vertical movements.

Rotary encoder function
(Rotary encoder function)
0 ... 4
{ 0 }
The actual speed list value supplied by an incremental encoder to the FI can be used for various
functions in the FI.
0 = Speed measurement Servo mode, "Servo mode speed measurement": The actual motor
speed list value is used for the FI servo mode. The ISD control cannot be switched off in this
function.
1 = PID actual frequency value: The actual speed of a system is used for speed control. This
function can also be used for controlling a motor with a linear characteristic curve. It is also
possible to use an incremental encoder for speed control which is not mounted directly onto
the motor. P413 – P416 determine the control.
2 = Frequency addition: The determined speed is added to the actual setpoint value.
3 = Frequency subtraction: The determined speed is subtracted from the actual setpoint.
4 = Maximum frequency: The maximum possible output frequency / speed is limited by the
speed of the encoder.
