Operation with
highly precise
timing
Increasing accu-
racy of external
output ON time.
(Feeding, hole
opening, tape
winding, gluing,
and other appli-
cations)
High-precision
ON outputs, with
minimum unit of
0.01 ms
• One-shot pulse
outputs
(STIM(980)
instruction)
7-5 Pulse Inputs
Set pulse output operation mode to one-shot
output.
Specified outputs turn ON during specified inter-
val (0.01 ms to 9,999 ms).
Output OFF after specified time elapses is per-
formed by hardware, which gives accurate ON
time with no fluctuation.
Can be used within interrupt tasks because uses
special timer.

7-6-8 Time Measurement with the Pulse
Counter
Time measurement starts/stops with input inter-
rupt (MSKS(690) instruction) + STIM(980)
instruction within interrupt tasks. The elapsed
time is stored in Motion Control Module Auxiliary
Area. This data can be read using the PRV
instruction.
Note Pulse output 1 or pulse output 2 must be
set to pulse counter time measurement in
System Setup.

7-6-8 Time Measurement with the Pulse
Counter
Can be used to obtain output pattern each time
interval elapsed after timer start.
Timer accuracy can be selected from as low as
0.001 ms.
