5.8.4.5 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.
Parameter Info Lenze setting
Value Unit
C00274 SC: Max. change in acceleration 400.0 %/ms
Note!
Only activate this jerk limitation for speed-controlled applications!
