When one of these signals is set high, the CNC closes the positioning loop of the corresponding axis.
If set low, the CNC does not close the position loop of the axis. Any position deviation is stored as
following error, thus when the signal gets back high, the axis moves to return to position
These signals are controlled by the PLC and when the positioning loop is to be closed, they will be
processed by the CNC according to the value given to machine parameter "DWELL" (P17) for the
axes.
DWELL = 0
When a.m.p. DWELL (P17) for the axis to be moved is set to 0, the CNC will check the status of
the SERVOON signal at the time when the ENABLE must be output.
If the SERVOON signal is high, the CNC allows the movement of this axis by activating the ENABLE
signal and providing the required velocity command output.
On the other hand, if the SERVOON signal is low or if it changes during the movement of the axes,
the CNC stops the axes feed and the spindle rotation displaying the corresponding error message.
DWELL<>0
When a.m.p. DWELL (P17) for the axis to be moved is set to other than "0", the CNC will check the
status of the SERVOON signal at the time when the ENABLE must be output.
When this signal (SERVOON) is high, the CNC allows the movement of the axis by activating the
ENABLE signal and providing the required velocity command output.
On the other hand, if the SERVOON signal is low, the CNC activates the ENABLE signal and after
"waiting" for a time period indicated in DWELL, it checks again the status of the SERVOON signal.
If it is high, the required spindle velocity command will be output. If low, the CNC will stop the axes
feed and the spindle rotation displaying the corresponding error message.
Also, if the SERVOON signal changes states during the movement of the axis, the CNC stops the
axes feed and the spindle rotation displaying the corresponding error message.
