0 Disabled
The multi-function input is dis-
abled.
1 Auxiliary frequency
reference (FREF2)
When frequency reference 2 is se-
lected using the multi-step speed
references, the input analog sig-
nal for the CN2 terminal will be the
frequency reference. The n025
setting will be invalid.
Note: Set the Frequency Refer-
ence Gain in n068 or
n071, and the Frequency
Reference Bias in n069 or
n072.
2 to 3 Not used
4 Output voltage bias
(VBIAS)
Add the VBIAS to the output volt-
age after V/f conversion.
