Measured value of the current
Notes
The time that is set for the DO digital output on 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 pulse
train.
Value that is output with pulse-width modulation at the DO digital output
on expiration of the on-delay.
You can change the configured period duration:
Period duration = Factor × 0.1 × configured period duration
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 change the configured on-delay before the start of the output
sequence:
On-delay = Factor × 0.1 × configured on-delay
