Setting the minimum pulse duration and the minimum interpulse period
You assign the minimum pulse duration and the minimum interpulse period as DWORD
numerical value between 0 and 10 000 000 μs (10 s) with the help of the channel parameter
configuration "Minimum pulse duration".

Parameter
Meaning
Value range
Default
Reaction to
CPU STOP
Reaction to
CPU STOP
The parameter "Output substitute val-
ue" generates a substitute value upon
CPU STOP, which you can define with
the parameter "Substitute value for
pulse output (DQA)".
Output substitute value
Output

The parameter "Continue operation"
still generates the PWM output signal
upon CPU STOP, which was generated
before the CPU STOP.
Continue operation
Substitute
value for pulse
output (DQA)
If you have set the option "Output sub-
stitute value" for "Reaction to CPU
STOP", the parameter "Sub
stitute value
for pulse output (DQA)" defines the
substitute value to be used for the
pulse output of the channel.
If you have set the option "Continue
operation" for "Reaction to CPU
STOP", the parameter "Sub
stitute value
for pulse output (DQA)" cannot be
selected
0
(use substitute value 0)
0
1
(use substitute value 1)
Diagnostics
interrupt
No supply
voltage L+
The parameter "No supply voltage L+"
activates the diagnostic interrupt of the
channel in the case of no supply volt-
age L+
Deactivated
Deactivated
Activated
Parameter High-speed
output (0.1 A)
The "High-speed output (0.1 A)" pa-
rameter is used to specify whether you
want to use the selected pulse output
as high-speed output. Requirement for
this is that the selected pulse output
supports the operation as high-speed
output.
Deactivated
The output supports frequencies of
up to 10 kHz (load dependent) and
currents of up to 0.5 A or frequen-
cies of up to 100 Hz and currents of
up to 0.5 A depending on the per-
formance capability of the selected
output.
Deactivated
Activated
The output supports frequencies of
up to 100 kHz and currents of up to
0.1 A.
Output format Defines the format of the ratio value
(on-load factor) in the field
"OUTPUT_VALUE" of the control dura-
tion of the channel.
S7 analog output
Interprets the ratio value in the field
OUTPUT_VALUE" of the control
interface 1/27648 of the current
period duration.
Supported value range from 0 to
27 648
