5.3 Modes and Functions
Setting Times Using a Time Base
Select, by means of the time base that can be assigned parameters, the resolution and
range of the period duration, the pulse duration, and the on-delay.
Time base = 0.1 ms:
Time base = 1 ms:
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
Setting and Changing the Period Duration
Set the period duration as a value between 2 and 65535 in the parameters:
Period duration that has been assigned parameters = time base x set numerical value
Using the factor for the period duration, you can adjust the time that has been assigned
parameters in your control program. Set the factor between 0 and 255, with a weighting of
0.1:
Period duration = factor x 0.1 x period duration that has been assigned parameters
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 minimum/pulse
duration parameter:
Pulse duration that has been assigned parameters = time base x set numerical value
Setting the On-Delay
Set the on-delay as a value between 0 and 65535 in the parameters.
On-delay that has been assigned parameters = time base x set numerical value

been output, the output sequence is terminated, STS_ENABLE and the DO digital output
are deleted, and ERR_PULS is set. At the next output sequence, ERR_PULS is deleted.
You can set times from 0.2 ms to 6.5535 s with a resolution of 0.1 ms.
You can set times from 1 ms to 65.535 s with a resolution of 1 ms.
