P105 (P)
Maximum frequency
always visible
0.1 ... 400.0 Hz
[ 50.0 ]
The frequency supplied by the FI after being enabled and once the maximum setpoint is present, e.g.
analog setpoint as per P403, a correspondingly fixed frequency or maximum via the ControlBox.
This frequency can only be overshot by the slip compensation (P212), the function "Maintain
frequency" (function digital input = 9) or a change to another parameter set with lower maximum
frequency.
P106 (P)
Ramp smoothing
always visible
0 ... 100 %
[ 0 ]
This parameter enables a smoothing of the acceleration and deceleration ramps. This is necessary for
applications where gentle, but dynamic speed change is important.
Ramp smoothing is carried out for every setpoint change.
The value to be set is based on the set acceleration and deceleration time, however values <10% have
no effect.
The following then applies for the entire acceleration or deceleration time, including rounding:
