Machine data 2700* assigns the master spindle to a slave for speed setpoint coupling. The
speed setpoint is taken from the spindle entered here and output as the speed setpoint while
ignoring its own position control. The assignment is made with the axis/spindle number.
Value
Meaning
2701*
Default value
0
Machine data 2701* assigns the master spindle to a slave. The torque setpoint is taken from
the spindle entered here and compared with the torque setpoint of its own drive. The
difference is the input variable for the torque compensation controller.
The assignment is made via the axis/spindle number.
If the default value 0 is entered, the master of the speed setpoint coupling (MD 270*) is also
used for the torque compensation control.
