6.1 Configuration
The two axes have separate machine parameters. The additive
coupling is configured with the axis machine parameters
"SWITCHAX" and "SWINBACK" of the DRO axis.
Likewise, we recommend to set general machine parameter
"DIPLCOF=2" so the motorized axis position display shows the
PLCOF* component.
SWITCHAX (P65) This DRO axis parameter indicates which is the main axis it is
associated with.
SWINBACK (P66) This DRO axis parameter indicates that an additive coupling is to be
carried out on the axis indicated by parameter "SWITCHAX".
6.2 PLC program
We recommend to manage the compensation through PLCOFZ with
a periodic subroutine whose period is the same as the time set in
LOOPTIME.
The SWITCH* mark is not involved in the additive coupling.
The following example assumes that the Z axis is motorized and that
the W axis is a DRO axis. The W axis is coupled with the Z axis.
0 None 1 - X axis 2 - Y axis 3 - Z axis 4 - U axis
5 - V axis 6 - W axis 7 - A axis 8 - B axis 9 - C axis
By default: 0
