4.7.3. How to check the action of total pulses
Description
z
Checks the action of total pulse output.
The output action can be verified upon setting the number of pulses to be outputted per second.
Settable range: 1 to 100 pulses/s. (DO1 only)
Note: 1. The output pulse width is as currently set (see Section 4.5.6.1.)
Set the frequency taking the pulse width into account referring to the following expression.
Pulse count setting
1000/(pulse width [ms] u2)
Example: If the pulse width is set at 50 ms, select 10 pulses/s or less.
Note: 2. DO1 (transistor open collector) and DO2 (relay contact) operate simultaneously.
Before checking the action, confirm whether proceeding to an action is all right or not.
Note: 3. DO2 (relay contact) always operates at the rate of 1 pulse/sec.
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand
(Section 4.4.1).
Typical operation Output 5 pulses/s.
