HEIDENHAIN MANUALPLUS 620 Technical Manual

6.14.1 Gantry axes
In gantry axes, tandem tables, etc., two servo-controlled axes are coupled so
that they can move only simultaneously. The main axis is referred to as the
master, and the tracking axis as the slave.
Because a gantry coupling is configured exclusively over the slave axis, it is
possible to assign more than one slave to the same master. However, a gantry
slave axis cannot at the same time serve as a gantry master axis.
The function is effective during control both with following error and with
velocity feedforward and can be used for digital and analog drive control.
Activating gantry
axes
In principle you can couple axes with each other statically without intervention
by the PLC in the startup phase or dynamically with Module 9126 during
program run. In both cases, however, it is necessary to configure the axis
coupling beforehand in the machine parameters.
Static activation of
gantry axes
To activate a static axis position coupling, i.e. during startup of the
MANUALplus 620 and without action by the PLC, proceed as follows:
 Assign a master axis to the slave axis. In MP_masterAxis, enter the key
name of the master axis from the list parameter MP_axisList of the entity
CfgAxes.

Note
The master and slave axes must be on the same drive-control main board,
which means that both axes need to be controlled by the same DSP. In this
way, you can flexibly assign the master and slave axes to the PWM outputs
X51 to X56 of a CC 6106. On controller units with more than one drive
control board (CC 6108, CC 6110), the master axis and the slave axis both
need to be assigned to either the A connections or the B connections.
Mixed connection is not permitted.
