In-position Function

The "in-position function" turns on In-position signal (X16) while the accumulated pulse amount in the deviation
counter is within the specified in-position range (1 to 20479pulse) after deceleration started.
In-position signal (X16) can be used as the signal right before positioning completion.
(1) Control detail
In-position signal (X16) turns on when the accumulated pulse amount in the deviation counter becomes equal to
the value set in "
v
In-position signal
(X16)
Accumulated pulse amount is checked with the in-position range every 0.5ms.
(2) Precautions for control
(a) During speed control in the speed-position control switch mode
Accumulated pulse amount is not checked with the in-position range.
(b) Timing at which In-position signal (X16) turns off
In-position signal (X16) turns off at the following timings.
• When OPR starts
• When positioning control starts
• When two-phase trapezoidal positioning control starts
