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)

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.

(Unit: 0.001 ms

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.
