IDN78 Linear Position Data Scaling Exponent

This parameter defines the scaling exponent for all position data in the amplifier, when lin-
ear scaling in IDN76 is selected. Refer to IDN77.

IDN79 Rotational Position Resolution

This parameter defines the rotational position resolution for all position data in the ampli-
fier. The LSB weight of rotational position data is determined by the following equation:
If the rotational position resolution is different from the internal resolution of the amplifier

IDN80 Torque Setpoint Value

The master issues torque setpoints to the amplifier as cyclic data through IDN80. Torque
setpoints written via the service channel do not take affect.
