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".
Parameters of the pulse width modulation (PWM) mode
Reaction to
CPU STOP
Reaction to CPU
STOP
The parameter "Output substitute
value" generates a substitute
value upon CPU STOP, which you
can define with the parameter
"Substitute value for pulse output
Output substi-
tute value
The parameter "Continue opera-
tion" still generates the PWM out-
put signal upon CPU STOP, which
was generated before the CPU
Substitute value
for pulse output
(DQA)
If you have set the option "Output
substitute 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 "Contin-
ue operation" for "Reaction to CPU
STOP", the parameter "Substitute
value for pulse output (DQA)"
cannot be selected
0
(use substitute value 1)
Diagnostics
interrupt
No supply voltage
L+
The parameter "No supply voltage
L+" activates the diagnostic inter-
rupt of the channel in the case of
Deactivated
Parameter High-speed output
(0.1 A)
The "High-speed output (0.1 A)"
parameter is used to specify
whether you want to use the se-
lected pulse output as high-speed
output. Requirement for this is that
the selected pulse output supports
the operation as high-speed out-
put.
The output supports frequencies
of up to 10 kHz (load dependent)
and currents of up to 0.5 A or
frequencies of up to 100 Hz and
currents of up to 0.5 A depending
on the performance capability of
Deactivated
The output supports frequencies
of up to 100 kHz and currents of
