The
FirstPosition
can be less than, equal to, or greater than the
LastPosition.
If the
FirstPosition
is
greater than the
LastPosition
, the setting will straddle the modulo minimum position setting value.
•
An instruction error will occur if a position beyond the upper and lower limits of the ring counter is
specified.
For details on latching, refer to the MC_TouchProbe (Enable External Latch) and MC_AbortTrigger
(Disable External Latch) instructions in the
NJ-series Motion Control Instructions Reference Manual
(Cat. No. W508).
This function detects whether the command position or actual position of an axis is in the specified
range (zone). Use the MC_ZoneSwitch (Zone Monitor) instruction to specify the first position and last
position of the zone to check. The
InZone
output variable for the Zone Monitor instruction will change to
TRUE when the position of the axis enters the specified zone. You can also specify multiple zones for a
single axis. Zones can overlap.
For details on zone monitoring, refer to the MC_ZoneSwitch (Zone Monitor) instruction in the
NJ-series
Motion Control Instructions Reference Manual
(Cat. No. W508).
