IDN81 Additive Torque Setpoint
The master issues additive torque commands to the amplifier as cyclic data via IDN81.
Values written via the service channel do not have any effect. This is an additional func-
tion, which is used to influence the torque in the drive in order to minimize following
errors. This value is added to the torque command. This function can be used for position
and speed control. It should not be set together with automatic acceleration feed forward
P-IDN 3052, since both functions write the internal variable “IVORCMD” (see also IDN
P3052).
