Typically the software overtravels are located within the hardware
overtravels (maximum axis travel defined by the limit switches on each
axis), and they are used to keep the axes within the range your system
installer determines is usable for that particular machine’s application.
The area defined by the software overtravels becomes effective after
completion of the initial homing operation at power up. For details on how
the control reacts to a entry into an overtravel area, see page 12-13.
CAUTION: The area defined by a software overtravel does not
take in to account any offsets. This allows the actual tool to
enter the restricted area without the axes absolute position
entering it. Make sure this is considered when the software
overtravel is established.
