Optimise response to setpoint changes and determine mass inertia
Setting the total moment of inertia under
feedforward control. Depending on the application, an adjustment of the setting under
C00273
may be necessary to optimise the response to position/speed setpoint changes by
means of the torque feedforward control.
Without feedforward control:
n, M
C00273
set too high:
n, M
Actual speed value (signal nMotorSpeedAct)
Speed setpoint (signal nMotorSpeedSet)
Speed controller output (signal nOutputSpeedCtrl)
[5-15] Typical signal characteristics for different settings of the load moment of inertia
