YASNAC PCNC I/O Signal Function Manual Chapter 9: Automatic Support Functions
Set the axis number (1 to 5) of the axis to be monitored for the position monitor
check axis number parameters. For the axis movable range boundary setting
parameters, set the movable range of the axis to be monitored in the machine
coordinate system values.
Axis position is monitored in intervals of 64 msec and the result of monitoring for
the 1st to 10th position monitor range is output to PMON1 to PMON10.
The position monitor function is valid disregarding of the operation mode after the
completion of origin return.
IMPORTANT!
1. The position monitor function is not valid for a rotary axis.
2. If the machine coordinate position of an axis is on the boundary of position monitor range, the
output signal “closes”.
3. The boundary of the position monitor range is always set in the mm unit system. Setting it in
an inch unit system value is not allowed.
With the PCNC, position monitor is possible for up to eight ranges (#36340 to
#36347). High-speed monitoring is possible for on of these eight ranges.
Designation of the high-speed monitoring is made by the high-speed monitor range
designation input signal. For details of the high-speed monitoring, refer to 9.11.
