6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.9 MDs for parameter set switchover
2560*-
Emergency retraction threshold 2nd - 8th parameter as
2566*
Default value
400
These MD have the same meaning as MD 493*, see also "Functional Descriptions: Parameter
set switchover".
2567*-
Time const. speed link path 1st to 8th par. set
2574*
Default value
0
These machine data are active only with gear interpolation.
2700*
Default value
0
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 No axis/spindle
2701*
Master for torque compensation control
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.
Value
Meaning No axis/spindle
