F660 — Adding Input Selection enables or disables output frequency adjustment via an external
source. If enabled, the selected input is used as a modifier of the programmed Output Frequency.
F661 — Multiplying Input Selection enables or disables output frequency adjustment via an external
source. If enabled, the selected input is used as a multiplier of the programmed Output Frequency.
F702 — Display Unit Multiplication Factor provides the multiplier for the displayed frequency value
on the EOI.
For example: Given a multiplication factor of 0.5, an output frequency of 100 Hz would be displayed as
50.
The multiplier allows the EOI to be used to display the rate at which a commodity is being processed by
the system in process units per time.
F703 — Display Unit Selection is used in conjunction with F702 to define which frequency values
displayed on the EOI will be affected by the Multiplication Factor (F702).
•
All Frequencies - Only PID frequency-limiting parameters F364, F365, F367, and F368 ARE NOT
affected by F702.
•
PID Process Data - Only PID frequency-limiting parameters F364, F365, F367, and F368 ARE
affected by F702.
F729 — Panel Override Multiplication Gain provides a value to be used if the Multiplying Input
Selection (F661) is set to 4 – F729 Setting.
Discrete Input/Output Terminals — ASD discrete input terminals (F111 – F118) and output terminals
(F130 – F132) have several PID-related parameters that can be programmed.
See Table 4 and Table 5.
