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.
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.
