6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.7 Axis-specific MD 2 (axial data 2)
1428*
Default value
0
These machine data are only used for the functionality "Electronic gearbox".
Together with the installed test function (activated with NC MD 1844* bit 5), these machine
data are used to set the control behaviour of the PID compensatory controller.
For additional information see the functional description of the electronic gearbox.
Note:
As from SW 4, for 8 parameter sets
1432*
Default value
6 000
This machine data is only used for the functionality "Electronic gearbox".
The parallel model must be set to the time constant of the position control loop of the following
axis (time constant T=1/servo gain).
If the value 16000 is entered in the machine data, the system automatically calculates the
actual servo gain factor and the time constant of the following axis. However, this actual servo
gain factor is only stored internally, it cannot be looked at.
The value 16000 entered for the time constant is also automatically replaced by the value
derived by the control.
