Output” is “Stepper Motor.”

Range of values is 0 to 100% in increments of 1%.

Factory Default is 0%.

AF Adjustable Speed Control Algorithm

Enable

The following is displayed only if the Starter Type is

“Adaptive Frequency” or “AFDB” or the Compressor

Power Source is Engine/Generator.

Possible values of [d/e] are: Disable and Enable

(Factory Default).

AF Leaving Water Standard Deviation

The following is displayed only if the Starter Type is

“Adaptive Frequency” or “AFDB” or the Compressor

Power Source is Engine/Generator.

Range of values is 0.5 to 4.0 in increments of 0.1.

Note: The above value entered is 1.316 X 10^9 / (#

Stages X (Impeller Dia ^2)) all divided by 1000 for the

purpose of display and IPC data transmission (e.g.

the actual range is 0-2,000,000 in increments of

1000). In the chiller module it is multiplied by 1000

again so it is properly scaled.
