Ramp smoothing
P106
(Ramp smoothing)
0 ... 100 % This parameter enables a smoothing of the acceleration and deceleration ramps. This is
necessary for applications where gentle, but dynamic speed change is important.
{ 0 }
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:

Under the following conditions ramp rounding is switched off or replaced with a
linear ramp with extended times:
• Acceleration values (+/-) less than 1 Hz/s
• Acceleration values (+/-) greater than 1 Hz/ms
• Rounding values less than 10 %
