P105
Maximum frequency
(Maximum frequency)
P
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. analogue 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.
Maximum frequencies are subject to certain restrictions, e.g.
• Restrictions in weak field operation,
•
Compliance with mechanically permissible speeds,
•
PMSM: Restriction of the maximum frequency to a value which is slightly above the rated
frequency. This value is calculated from the motor data and the input voltage.

P106
Ramp smoothing
(Ramp smoothing)
P
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:
