Zone/Overtravel Parameters
Chapter 6
6-13
The software overtravel cannot be canceled on the control. AMP is the
only means available to activate, deactivate, and establish the range for the
software overtravel. These subsections offer a discussion of parameters
used to establish the software overtravel:

Positive Software Overtravel
6-14
Negative Software Overtravel
6-15
Important: Note that the software overtravel is only effective provided
that a homing operation has been conducted for that axis. If the axis has
not been homed, there is no machine coordinate system from which the
software overtravel can be referenced.
Function
This parameter is used to determine whether the software overtravel is
used for a specific machine application. Setting a value of “True” for this
parameter causes the software overtravel to be active for that axis. Setting
a value of “False” for this parameter disables the software overtravel for
that axis.
