4.11.3. How to check the action of total pulses
Description
z 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 (DO1/DO2 only)
Note 1) The output pulse width is as selected currently. (See 4.9.2.1.)
Set the frequency taking the pulse width into account referring to the following expression.
The number of setting pulses d 1000/(Pulse width[ms] × 2)
Example: If the pulse width is set at 50ms, select 10 pulses/s or less.
Note 2) DO1/DO2 (transistor open collector) and DO3 (relay contact) operate simultaneously.
Before checking the action, confirm whether proceeding to an action is permitted.
Note 3) DO3 (relay contact) always operates at the rate of 1 pulse/sec regardless of setting.
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand. (See Section 4.4.1.)
Operation
(example) Perform pulse output of 5 pulses/s.
