Omron FQM1-MMA21 Pulse Output Starting Conditions, One-shot Pulse Output Function Example

Pulse Outputs Section 7-6

get Frequency Not Reached Flag (A624.02 or A625.02) will turn ON at the peak of the triangular pattern and turn OFF when deceleration is completed.

One-shot Pulse Output Function Example

In this example, STIM(980) is used to generate a 1.5-ms one-shot pulse out- put from pulse output 1.

0002.00

@STIM

#1

#000F

#0

When CIO 0002.00 goes ON, STIM generates a 1.5-ms one-shot pulse output from port 1.

Pulse Counter Time Measurement (Timer) Example

In this example, a pulse counter timer is allocated to pulse output 1.

0002.00

@STIM

#B

#0

#0

0003.00

@STIM

#B

#1

#0

When CIO 0002.00 goes ON, STIM starts pulse counter timer 1 (allocated to port 1).

When CIO 0003.00 goes ON, STIM stops pulse counter timer 1.

The measurement results are stored in Auxiliary Area words A620 and A621.
