Sets the positive logic (turning on the input will
turn on the near-point signal).
Sets the positive logic (turning on the input will
turn on the zero-phase signal).
If X012 is turned on, the variable speed pulse
output (PLSV) instruction will be activated to
accelerate or decelerate the operation.

Sets X007 for interrupt inputs.
Interrupt positioning (DVIT) instruction will not
be used for the pulse output destinations
Y001, Y002, and Y003.
Do not use.
Sets the negative logic (turning off the input
will turn on the interruption signal).
If X010 is turned off (if the NC contact is
turned on), the limit switch will be activated.
If X011 is turned off (if the NC contact is
turned on), the limit switch will be activated.
Do not use.
