Omron FQM1-MMA21, FQM1-CM001 One-shot Pulse Output STIM980, Pulse Counter Timer Function STIM980

Pulse Outputs Section 7-6

•Select pulse output 1 or 2.

2.Wire the output.

•Output: CW and CCW

•Output power supply: 5 V DC

3.Make the necessary System Setup settings (Pulse Output Tab Page − Op- eration Mode).

•Set the pulse output operation mode (in the Pulse Output Tab Page − Operation Mode) to relative pulse output or absolute linear pulse output.

•Set the clock speed for pulse outputs 1 and 2.

4.Create the necessary ladder programming.

•Use PLS2(887) to start pulse output control with trapezoidal acceleration/ deceleration from the specified port (acceleration and deceleration are specified separately).

•Use INI(880) to stop pulse output from the specified port.

•Use PRV(881) to read the pulse output PV of the specified port.

One-shot Pulse Output (STIM(980))

1,2,3... 1. Determine pulse output port.

•Select pulse output 1 or 2.

2.Wire the output.

3.Make the necessary System Setup settings.

•Set the pulse output operation mode (in the Pulse Output Tab Page − Operation Mode) to 1 shot.

4.Create the necessary ladder programming.

•Use STIM(980) (with C1 = #0001 or #0002) to turn ON the one-shot pulse output.

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

1,2,3... 1. Determine pulse output port.

•Select pulse output 1 or 2.

2.Make the necessary System Setup settings.
