Standard output (100 Hz output)
– Frequency (OUTPUT_VALUE) 0.1 Hz to 100,000 Hz
The new frequency is applied at the start of the next period. The new frequency has no
impact on the falling edge or the pulse-cycle ratio. However, the application can take up to
10 s depending on the previously set frequencyThe configured output frequency is output with a frequency-dependent accuracy at the digital
output PWM DQA. You can find an overview of the accuracy as a function of the frequency
used in the section Interconnection overview of outputs (Page 111Reaction 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
(DQA)".
Output substitute value Output substitute
value
The parameter "Continue operation"
still generates the frequency
output signal upon CPU STOP,
which was generated before the
CPU STOP.

Substitute value
for pulse output
(DQA)
If you have set the option "Output
substitute value" for "Reaction to
CPU STOP", the parameter "Substitute
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 "Substitute
value for pulse output (DQA)"
cannot be selected. The parameter "No supply voltage
L+" activates the diagnostic interrupt
of the channel in the case of
no supply voltage L+

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 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
frequencies of up to 100 Hz and
currents of up to 0.5 A depending
on the performance 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 value for the frequency
output in the field
"OUTPUT_VALUE" of the control
duration of the channel.
1 Hz
Interprets the value of the frequency
output in the field
"OUTPUT_VALUE" as frequency
with the unit Hz.

Pulse output
(DQA)
The parameter "Pulse output
(DQA)" is used to define the hardware
output that you want to use
as pulse output channel.
