• Set the pulse output operation mode (in the Pulse Output Tab Page 

−

Operation Mode) to Calculation (time measurement).

3.

Create the necessary ladder programming. 

a.

Use STIM(980) with C1 = #000B or #000C and C2 = #0000 to start
measurement.

b.

Use STIM(980) with C1 = #000B or #000C and C2 = #0001 to stop
measurement.

The STIM(980) pulse counter timer function used at the same time as an
STIM(980) timer interrupt function (one-shot timer or scheduled timer).

In the following positioning example, the PULS(886) and SPED(885) instruc-
tions are used to control a relative pulse output from port 1 (CW independent
mode positioning). The number of pulses specified in PULS(886) (10,000) are
output at the frequency specified in SPED(885) (2,000 Hz).

!Caution Be sure that the pulse frequency is within the motor’s self-starting frequency

range when starting and stopping the motor.

When CIO 0002.00 turns ON, 
PULS sets port 1 for 10,000
pulses (relative pulse output).
