6.9.3 Programming axis-specific setpoint/actual values
A setpoint value channel (i.e. a logical drive number) and at least one actual
value channel must be assigned to each axis/spindle for the position measuring
system. An optional second channel may be specified for a second position
measuring system.
The motor measuring system is always used for the speed regulation (X411).
The following fixed assignment is used between the motor connection and the
motor measuring system connection: The motor and motor measuring system
must always be connected to the same module.
