If TM_CTRL_DQ = 0, the user program takes over the control and the user can set the
output PWM DQA directly via the control bit SET_DQA.A deactivation of the software enable (SW_ENABLE = 1 → 0) cancels the current output
sequence. The last cycle 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.
Minimum pulse duration and minimum interpulse period
You assign the minimum pulse duration and the minimum interpulse period with the help of
the parameter "Minimum pulse duration".
● A pulse duration determined by the technology function or PWM channel which is shorter
than the minimum pulse duration will be suppressed.
● A pulse duration determined by the technology function or PWM channel which is longer
than the cycle duration less the minimum interpulse period will be set to the value of the
cycle duration (output switched on permanently).OUTPUT_VALUE assigns the on-load factor for the current period duration. You select the
range of the field OUTPUT_VALUE of the control interface with the "Output format"
parameter.
● Output format per 100: Value range between 0 and 100
Pulse duration = (OUTPUT_VALUE/100) x period duration.
● Output format 1/1000: Value range between 0 and 1 000
Pulse duration = (OUTPUT_VALUE/1 000) x cycle duration.
● Output format 1/10000: Value range between 0 and 10 000
Pulse duration = (OUTPUT_VALUE/10 000) x cycle duration.
● Output format "S7 analog output": Value range between 0 and 27,648
Pulse duration = (OUTPUT_VALUE/27 648) x period duration.
You assign OUTPUT_VALUE directly via the control program. A new OUTPUT_VALUE is
applied at the output when the next rising edge occurs.
Setting and changing the period duration
● Permanent updating
The period duration is permanently controlled via the control interface. The MODE_SLOT
bit must be set ("1" means permanent updating); LD_SLOT must be set to value 1 ("1"
means period duration). Set the period value in the field SLOT. The unit is always a
microsecond.
– High-speed output activated: between 10 μs and 10 000 000 μs (10 s) in the field
SLOT
– High-speed output deactivated: between 100 μs and 10 000 000 μs (10 s) in the field
SLOT
– Standard output (100 Hz output): between 10 000 μs (10 ms) and 10 000 000 μs
(10 s) in the field SLOT
● Individual updating
Set the period duration in the configuration parameters. Alternatively, execute an
individual updating via the control interface. MODE_SLOT must be deleted ("0" means
individual updating); LD_SLOT must be set to value 1 ("1" means period duration). Set
the period duration value in the field SLOT. The unit is always a microsecond.
– High-speed output activated: between 10 μs and 10 000 000 μs (10 s) in the
parameters
– High-speed output deactivated: between 100 μs and 10 000 000 μs (10 s) in the
parameters
– Standard output (100 Hz output): between 10 000 μs (10 ms) and 10 000 000 μs
