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.
• We recommend defining a limit value of one or two
times the motor slip frequency.
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.

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).
