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.
