Adapting the max. acceleration change (jerk limitation)
In the default setting of 400 %/ms of the max. acceleration change (
), jerk limitation is
switched off.
The setting defines the permissible maximum torque change per ms (based on the rated motor
torque).
Via the max. acceleration change that can be set in
, the change of the
setpoint torque can be limited for jerk limitation. Hence, sudden torque step
changes can be avoided. The entire speed characteristic is smoothed.
