Offset Authority (CP-76)

Offset Authority determines the quantity of the offset term (amount of

influence) for a given analog input level.

Offset Polarity (CP-77)

Offset Polarity determines if the offset term is added or subtracted from

the follower scaled reference. If CP-77 is set to 1 (additive), analog

input voltages greater than CP-75 (Offset Null) will cause an increase in

follower speed. Analog input voltages less than Offset Null will cause a

reduction in follower speed.

If CP-77 is set to 2 (subtractive), analog input voltages greater than

Offset Null will cause a decrease in follower speed. Input voltages less

than Offset Null will cause an increase in speed.
