Select Pulse input when using a pulse sequence as either reference or feedback. Scaling is done in par. group

Select which ramp to use. Logic "0" will select ramp 1 while logic "1" will select ramp 2.

The input terminal, for which the Run permissive has been programmed must be logic "1" before a start com-
mand can be accepted. Run permissive has a logic 'AND' function related to the terminal which is programmed
