* The number of target point number outputs that can be used depends on I/O assignment type.

2) The Zone 0 output signal is enabled and set to positive output by the Zone
output selection parameter (PRM53).
3) Set the movement point as P6.
(1) Although the robot is within the P1 ± OUT valid position range (point zone output range), all
the PO0 to PO3 target position point number outputs are off because P1 is not the movement
point. Moreover, the ZONE 0 output is also off because the robot is not within the specified
zone output range.
(2) All the PO0 to PO3 target position point number outputs are off because the robot is not
within the point zone output range. Moreover, the ZONE 0 output is also off because the
robot is not within the specified zone output range.
(3) The corresponding point number P6 is output to PO0 through PO3 (P1, P2 are on; P0, P3 are
off) because the robot is within the P6 ± OUT valid position range (point zone output range),
and because P6 is the movement point. ZONE 0 remains off at this time because the robot is
not within the specified zone output range.
(4) The ZONE 0 output turns on because the robot is within the specified zone output range
(P900 to P901). All the PO0 to PO3 target position point number outputs are off at this time
because the robot is not within any point zone output range.
