Limitation of the output frequency of the slip regulator and limitation of the injected stator frequency for the V/f
control ( VFCplus+encoder )

Subcodes Lenze setting Info
C00971/1 10.00 Hz Maximum output / correcting variable of the slip
regulator
• The slip regulator output is limited to the value set
here in motor/generator mode.
• It is recommended to select 1 to 3 times the slip
frequency of the motor as limit value.
C00971/2 100.00 Hz Maximum frequency deviation between the rotational
frequency (speed) measured mechanically by the
encoder and the injected stator frequency.
• A limitation may e.g. avoid overcurrent interruption
when traversing to a fixed limit stop.

d
= 5C33
h
Proportional gain of the slip regulator for V/f control ( VFCplus+encoder )
• The gain must be selected depending on the drive system and the sensor resolution (range: 0.005 ... 5).
• A high gain requires a high number of increments.

h
Integral time constant of the slip regulator for V/f control ( VFCplus+encoder )
• In general, the time constant should be selected in a range of 20 ms (high dynamics) to 200 (low dynamics).

h
Gain of the direct-axis current difference (Id) between setpoint and actual current for the voltage model of the
sensorless vector control ( SLVC )
• The gain should be selected in a range of 0 ...1 %.
