Select via
‘Channel’
the channel and select for pulse width modulation via
‘Operating
mode’
the operating mode
‘Pulse width modulation’
. Default values and structure of this
dialog box depend on the selected
‘Operating mode’
. The following parameters are sup-
ported:
1
Period
2
On-delay
3
Pulse duration
4
Pulse pause

Description
Assignment
Output format
Here specify the range of values for the output. The CPU
hereby determines the pulse duration:
n
Per mil
–
Output value is within 0 ... 1000
–
Pulse duration = (Output value / 1000) x Period
n
S7 Analog value:
–
Output value is Siemens S7 analog value 0 ...
27648
–
Pulse duration = (Output value / 27648) x Period
Per mil
Time base
Here you can set the time base, which will apply for resolu-
tion and range of values of the period duration, minimum
pulse duration and on-delay.
n
1ms: The time base is 1ms
n
0.1ms: The time base is 0.1ms
n
1µs: The time base is 1µs
0.1ms
On-delay
Enter here a value for the time to expire from the start of
the output sequence to the output of the pulse. The pulse
sequence is output at the output channel, on expiration of
the on-delay.
Range of values: 0 ... 65535 from this there are the fol-
lowing effective values:
n
Time base 1ms: 0 ... 65535ms
n
Time base 0.1ms: 0 ... 6553.5ms
n
Time base 1µs: 0 ... 65535µs
