Meaning
Set the "Pulse train" operating
mode.
Using the time base, select the
resolution and range of the
period duration, pulse duration,
and on-delay.
You can use the DI digital input
as an input or as a HW enable.
The time from the start of the
output sequence to the output
of the pulse train.
Pulse duration:
Enter the response time of the
actuator connected on your DO
digital output.
The period duration should
always be a multiple of the
response time of the actuator
connected to the DO digital
output.
Define the period duration
according to the required
repetition rate of the pulses.
You can change the time period
in your control program using
the "Time period factor".
