Comp_F
Setpoint value friction compensation
The parameter can be used, for example, to assess the
component of the feedforward control from the friction
compensation by means of measured data recording
(trace).
974
Comp_T
Setpoint value inertia compensation
The parameter can be used, for example, to assess the
component of the feedforward control from the inertia com-
pensation by means of measured data recording (trace).

Node_T
Support point torque [Nm]

Tab. 373 Legend for the block diagram of pilot control
Certain parameters of the pilot control are not entered in user units, but in Nm or rad/s and their
respective diversions, for example. The conversion of the user unit to rad/s is carried automatically
by the device.
The inertia for the inertia compensation is stipulated in kgm² (Px.973) and the support points of the
table for the friction compensation Node_T (Px.976) in Nm and Node_v in rad/s (Px.977).
