•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.

Note 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).

7-6-14 Pulse Output Function Examples

Positioning using Pulse Outputs without Acceleration/Deceleration

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).

Frequency

Number of pulses = 10,000 (Specified by PULS instruction.)

Target frequency 2,000 Hz

SPED executed.	Output stops after 10,000
	pulses have been output.

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

Starts pulse output from port 1 at 2,000 Hz (2 kHz) in CW independent mode.
