0 Always
Specify the new position to be substituted with the current position upon an input signal ("position
preset (16)" assigned to a CONT signal). After position preset is turned on, the current position
changes to the reference value of this parameter.

Specify to perform interrupt positioning.
Specify the traveling amount based on the position located at the timing of activation of an input signal
("interrupt input (49)" assigned to CONT signal).

exceeds the reference value.
Enter settings so that Positive software OT detection position is larger than Negative software OT
detection position.
(2) Position command format
Normal PTP: Motion is conducted in the range from -2000000000 to 2000000000 [unit amount].
Absolute/incremental positioning data designation and various position detection
functions can be used.
