Checking the total pulse output action

Description
● Checks the action of total pulse output.
The output action can be checked upon designating the number of pulses to be outputted per second.
Settable range: 1 to 100 pulses/s (when pulse width is 5ms, 10ms, 50ms,100ms or 200ms)
Note 1) The output pulse width is as selected currently. (See 4.8.2.1.)
Set the frequency taking the pulse width into account referring to the following expression.
The number of setting pulses  1000/(Pulse width[ms] × 2)
Example: If the pulse width is set to 50ms, select 10 pulses/s or less.
Note 2) When pulse width is 500ms and 1000ms, output action is performed at the rate of 1pulse/4seconds regardless of setting.
● This operation sets DO1 and the same contact action.
● Before operation, check whether DO output testing is permitted.
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)
