6.9.3 Setting the axis-specific setpoint/actual value parameters
One setpoint channel (i.e. a logical drive number) and at least one actual-value
channel for the position measuring system must be assigned to each axis/
spindle. A second channel for a second position measuring system can be spe-
cified optionally.
The motor measuring system (X411) is always used for the speed control func-
tion. The table below shows the fixed assignment between the motor connec-
tions and motor measuring system connections:
The motor and motor measuring system must always be connected to the same
module.
