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. The requirement for this is
that the selected pulse output
supports 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.Defines the format of the ratio
value (on-load factor) in the field
"OUTPUT_VALUE" of the control
interface of the channel.
S7 analog output
Interprets the ratio value in the
field OUTPUT_VALUE" of the
control interface as 1/27648 of
the current period duration.
Supported value range from 0 to
27 648
1/100
1/100
Interprets the ratio value in the
field "OUTPUT_VALUE" of the
control interface as percentage
value of the current period duration.
Supported value range 0 to 100
1/1000
Interprets the ratio value in the
field "OUTPUT_VALUE"of the
control interface as a one-tenth
percentage point of the current
period duration.
Supported value range from 0 to
1 000
1/10000
Interprets the ratio value in the
field "OUTPUT_VALUE" of the
control interface as a onehundredth
percentage point of the
current period duration.
Supported value range from 0 to
10 000
Minimum pulse
duration
Defines the minimum pulse duration
and the minimum interpulse
period of the output signal of the
channel. The channel suppresses
all pulses and pauses that are
below the specified value.
0 μs to 10 000 000 μs (10 s) 0 μs
Period duration Defines the period duration of the
output signal of the channel in μs.
In RUN, the user program can
control the period duration via the
control and feedback interface of
the channel.

software enable (SW_ENABLE 0 → 1). The feedback bit STS_SW_ENABLE indicates that
the software enable is pending at the pulse generator.
If the software enable is activated (rising edge), STS_ENABLE is set. The output sequence
runs continuously, as long as SW_ENABLE is set.
Note
Output control signal TM_CTRL_DQ
? If TM_CTRL_DQ = 1, the technology function takes over the control and generates pulse
sequences at the output PWM DQA.
? If TM_CTRL_DQ = 0, the user program takes over the control and the user can directly
set the output PWM DQA via the control bit SET_DQA.
Canceling the output sequence
Deactivating the software enable (SW_ENABLE = 1 → 0) during the frequency output
cancels the current output sequence. The last period duration is not completed.
STS_ENABLE and the digital output PWM DQA are immediately reset to 0.
A renewed pulse output is only possible after a restart of the output sequence.You set the frequency with the OUTPUT_VALUE directly with the control program in the
control interface. The value is specified in the real format and the unit is always "Hz". The
possible range depends on the parameter "High-speed output (0.1 A)" as follows:
● High-speed pulse output deactivated
– Frequency (OUTPUT_VALUE) 0.1 Hz to 10 000 Hz
● High-speed pulse output activated
– Frequency (OUTPUT_VALUE) 0.1 Hz to 100 000 Hz
● Standard output (100 Hz output)
– Frequency (OUTPUT_VALUE) 0.1 Hz to 100 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 frequency.
Accuracy of the output frequency
The 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 the outputs (Page 99)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
(DQA)".
Output substitute value Output substitute
value
The parameter "Continue" 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"
for "Reaction to CPU STOP",
the parameter "Substitute value for
pulse output (DQA)" cannot be
selected. No supply voltage
