Code Display (Description)
Amount of slip compensation (% of rated slip, calculated from nameplates) during regeneration (power flows back from load
to motor).
S.312 Slip comp filter
Time constant (s) of the filter used for slip compensation. The lower this value, the faster the compensation, with improved
speed control. Excessively fast slip compensation may cause unwanted oscillations.
S.320 DC braking level
Amount of current (% of drive rated current) injected during magnetization and stopping phases.
S.400 Control mode
Set this parameter to "[0] Open loop V/f" when there is no encoder feedback available.
Set to "[1] Closed loop V/f" otherwise.
Possible selections:
S.401 Encoder ppr
Resolution of the encoder in use, expressed in number of pulses per mechanical revolution (ppr). It is a nameplate data of the
encoder.
S.450 Spd ctrl P-gainH
Proportional gain of speed PI regulator.
S.451 Spd ctrl I-gainH
Integral gain of speed PI regulator.
S.452 Spd PI High lim
Maximum allowed output of the speed PI regulator (% of maximum frequency, F.020). It represents the maximum amount of
slip that is allowed during motoring operation.
S.453 Spd PI Low lim
Minimum allowed output of the speed PI regulator (% of maximum frequency, F.020). It represents the maximum amount of
slip (negative) that is allowed during braking operation.
Note!
It is possible to configure gain scheduling for the speed PI regulator.
S.901 Save parameters
The execution of this command will save all the parameters into the permanent memory of the drive. All unsaved settings will
be lost if the power is cycled.
