commands. This is generally performed through activation of a home switch positioned
on the appropriate axis giving it a known physical location.
When the Homing command is entered at the control, the CNC will move the axis
towards the Home Switches at the Fast Home Speed until the switches have been
activated. Once the switches have been activated, motion stops and then the axis moves
in the opposite direction off switch at the Slow Home Speed. The moment that the
switch is deactivated, the position is recorded at the control, providing an absolute
reference point for future motion commands.
Absolute Home Position
Defines the position of the axis when the Home Limit Switch or Marker Pulse is detected.
Home Offset Distance
Allows the user to set an offset distance from the Home Limit Switch.
Home Switch Normally
If a Home Limit Switch is used, the user is prompted for switch polarity.
Home Direction
Determines which direction the axes will travel during phase one of the homing
sequence.
Use Marker Pulse
When enabled, the absolute home position will be assigned at the instant the marker pulse
is detected. It is recommended that the Marker Pulse be used for optimal homing
repeatability.
Use Software Travel Limits
The CNC is capable of running with software Overtravel limit switches based on
position. When enabled, this feature allows the user to select the fault logic of fault or
Fast Decel when active. Fault operates as hardware switches with immediate fault. Fast
Decel uses the fast Decel value to ramp down motion.
Maximum Travel Limit
If Software Overtravels are enabled, the user is prompted for the maximum travel of the
cutting machine.
Minimum Travel Limit
If Software Overtravels are enabled, the user is prompted for the minimum travel of the
cutting machine.
