7.2.8.3 Pulse value
This function allows the operator to define how many pulses will be output per unit counted. After selecting the
Pulse value function, press “Enter” to display the current unit:
1 pulse per
[1.0] unit
The current Pulse value will be displayed and can be changed by toggling the arrow keys.
The operator can choose between the pulse values:
0.001, 0.01, 0.1, 1.0, 10.0, 100.0
Pressing the “Enter” key confirms the entry.
7.2.8.4 Pulse width
This function allows the operator to change the width of the output pulse to be output. If the pulse width is too
large for the actual pulse number, it will be reduced automatically. In this case the warning “Pulse output
saturated” will be displayed.
After selecting the Pulse width function, press “Enter” to display the following selection field:
Pulse width
0050.0 ms
The current pulse width will be displayed and can be changed by toggling the arrow keys.
Pressing the “Enter” key confirms the entry.
The maximum output frequency can be calculated using the following formula:

If connecting to electrical counter relays, we recommend pulse widths greater than 4 ms; for electromechanical
counter relays the preset value should be 50 ms.
