Setting and Changing the Number of Pulses
Set the number of pulses directly as a numerical value between 0 and 65535 with your
control program.
If you change the number of pulses on expiration of the on-delay, the new value takes effect
immediately:
● If you have increased the number of pulses, the new, higher number of pulses is output.
● If you have reduced the number of pulses, and if the lower number of pulses has already
Set the time period and change when using the short control interface
Set the period duration as a value between 2 and 65535 in the parameters:
Configured time period = Time base x specified numerical value
Using the factor for the period, you can adjust the assigned time in your control program. Set
the factor between 0 and 255, with a weighting of 0.1:
Time period = Factor x 0.1 x configured time period
If you change the factor during the output sequence, the new period duration will take effect
at the start of the next output sequence.
Setting the Pulse Duration
Set the pulse duration as a numerical value between 1 and 65535 with the "Pulse duration"
parameter:
Configured pulse duration = Time base x Specified numerical value
When the long control interface is used, you can set the ratio of the pulse duration to the
interpulse period:
Pulse-pause ratio = (Setpoint / 255) × time period
Setting the On-Delay
Set the on-delay as a value between 0 and 65535 in the parameters.
Configured on-delay = Time base x specified numerical value
Isochronous mode
Generally applicable information is available in the section "Isochronous mode (Page 267)".
In the "Pulse train" operating mode, isochronous mode does not have any influence on the
functionality.
Measurement of current
For more information, refer to the section "Function: Measurement of current (Page 310)".

are deleted, and ERR_PULS is set. At the next output sequence, ERR_PULS is cleared.
