Notes
The time that is set for the DO digital output on expiration of the on-
delay.
You can change the on-delay that has been assigned parameters before
the start of the output sequence:
On-delay = factor x 0.1 x on-delay that has been assigned parameters
Value that is output with pulse-width modulation at the DO digital output
on expiration of the on-delay.
You can change the period duration that has been assigned parameters:
Period duration = factor x 0.1 x period duration that has been assigned
parameters
Number of pulses that are output at the DO digital output on expiration of
the on-delay.
You can change the period duration that has been assigned parameters
before the start of the output sequence:
Period duration = factor x 0.1 x period duration that has been assigned
parameters
The time between a negative edge at the DI digital input and its output at
the DO digital output.
You can change the on-delay that has been assigned parameters before
the start of the output sequence:
On-delay = factor x 0.1 x on-delay that has been assigned parameters
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 DO digital output.
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.
