The PLC sets one of these signals high to activate the additive handwheel on each axis. Only one
additive handwheel may be enabled at a time. If there are more than one mark active, only the first
one will be attended to.
When a program is in execution and the mark associated with an axis is activated, it calculates the
movement to be applied to that axis according to the resolution of the handwheel.
DIFFCOM1 (M5117) DIFFCOM2 (M5167) DIFFCOM3 (M5217) DIFFCOM4 (M5267)

Depending on the logic level of these signals, it corrects the theoretical difference between the
master and the slave of a Gantry pair after homing both axes of that pair of axes.
The theoretical difference between the master and the slave is corrected as follows:
• With the leading edge (up flank) of DIFFCOMaxis while SERVOaxisON = 1.
• With the leading edge (up flank) of SERVOaxisON while DIFFCOMaxis = 1.
In this case, to correct the theoretical difference between master and slave, both the master and
the slave axes must be set as Gantry axis or as DRO axis. Otherwise, the upflank of the
SERVOaxisON mark corrects the following error of the slave axis.
