Notes
Number of pulses that are output at the DO digital output on expiration of
the on-delay.
You can change the configured time period before the start of the output
sequence:
Time period = Factor x 0.1 x configured time period
When specifying the time period take into account the set minimum
pulse duration and the response time of your final controlling element
that is connected to the digital output DO.
You can set the ratio of the pulse duration to the interpulse period:
Pulse-pause ratio = (Setpoint / 255) × time period
The time between a negative edge of the digital input DI and its output
on the digital output DO.
You can change the configured on-delay before the start of the output
sequence:
On-delay = Factor × 0.1 × configured on-delay
The time between a positive edge of the digital input DI and its output on
the digital output DO.
Frequency that is output at the DO digital output after expiration of the
on-delay.
You can change the configured on-delay before the start of the output
sequence:
On-delay = Factor × 0.1 × configured on-delay
The time from the start of the output sequence to the output of the
frequency.
You use the control bit to select and deselect the function for directly
controlling the digital output.
You use the control bit to set the status of the digital output DO.
You must always issue the software enable in your control program. If
you don't use a HW enable, the output sequence will be started by the
positive edge of the software enable. If you delete the software enable,
the current output sequence will be terminated.
