Minimum pulse duration
This parameter is used to specify the minimum permitted pulse duration for the PWM signal.
Pulses and pauses which fall below the value are suppressed.
The default setting is "0 μs".
Note
The Minimum pulse duration is not effective if you have activated "Current control".
Period duration
This parameter is used to specify the period duration of the output signal.
In "PWM with DC motor" mode, the default setting is "1000 μs" (= 1 ms). In other operating
modes the default setting is "2000000 μs" (= 2 s).
Actual period duration
The actual period duration is only displayed in isochronous mode.
The displayed value is the utilized period duration, which is calculated from the input period
duration and the set application cycle.
On delay
This parameter is used to specify the delay with which the start of the output sequence
effects the output of the pulse.
The default setting is "0 μs".
Note
Isochronous mode
In isochronous mode you cannot set the On delay in the "Pulse width modulation PWM" and
"PWM with DC motor" modes.
Off delay
This parameter is used to specify the delay with which a falling edge of the digital input DIO
effects the digital output DQA.
The default setting is "0 μs".
