Adapting the max. acceleration change (jerk limitation)

In the default setting of 400 %/ms of the max. acceleration change (

C00274

), 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

C00274

, 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.
