1.000 / real32Defines the scaling factor for the torque reference (the
torque reference is multiplied by the value).
This allows drives sharing the load between two motors
on the same mechanical plant to be tailored to share
the correct amount each, yet use the same master
torque reference.

Zero / uint32Selects the source of torque reference additive 1.
Note: For safety reasons, the additive is not applied
when an emergency stop is active.
See the control chain diagram on page 751.
