3.4.1 CONSIDERATIONS ABOUT THE MACHINE REFERENCE
ZERO (HOME)
* If when initiating the home search, the home switch is pressed, the axis will move in the
opposite direction to the one determined by machine parameters "P62(4), P62(5)", until
the home switch is released and, then, it will start the home search.
* If the axis is positioned outside the travel limits specified by machine parameters "P0, P1,
P40 and P41", the axis must be jogged by hand into the work area and, then, position
it in the appropriate area for homing it.
* If the selected axis does not have a home switch installed, machine parameters "P22(8)"
and "P62(8)"), only the marker pulse searching move at 100 mm/min will be carried out
until the marker pulse (Io) of the feedback device is detected, thus concluding the home
search.
3.5 OPERATION OF THE CNC AS A DRO
When the Manual (DRO) input at pin 19 of connector I/O1 is set high (24 Vdc), the CNC
behaves like a DRO.
This means that:
* That the axes must be moved by means external to the CNC.
* The axis enable signals must be deactivated so they can be moved freely.
* If when operating in this mode, the axis travel limits set by machine parameters P0, P1,
P40 and P41 are overrun, the CNC will issue the corresponding error message.
