Adapting the max. acceleration change (jerk limitation)

Parameter
C00274
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).

Note!
Only activate this jerk limitation for speed-controlled applications!

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.
