serial port to change auxiliary frequency.
If VCI-5 or CCI-5 is selected, take 5V input as the
point corresponding to zero frequency, 0~5V input
corresponds to negative output, 5~10V input
corresponds to positive output. See Fig.5-60.

If PULSE-0.5×F1.03 is taken as auxiliary
frequency setting method, one half of F1.03 (max.
pulse freq.) as the point corresponding to zero
frequency, 0~0.5 times of F1.03 input
corresponds to negative output, 0.5~1 times of
F1.03 input corresponds to positive output. See
Fig.5-61.

F9.02: Analog auxiliary reference factor
It is valid when F9.01=4~12. The auxiliary
reference undergoes F9.02 gain calculation first,
and then output according to F1.00.

The auxiliary frequency will be saved in F9.03,
and the sign of the freq. saved in F9.04.

0: maintain the auxiliary freq. if the drive stops
1: preset frequency is cleared if the drive stops
Hundred’s place of F9.04: sign of auxiliary freq.
0: (+) positive sign.
Preset freq. is the sum of main freq. and auxiliary
freq.
1: (+) negative sign
Preset freq. is the result of main freq. minus
auxiliary freq.
Note
:
When the inputting mode of auxiliary reference
frequency is the same with that of main reference
frequency, the auxiliary reference frequency setting is
invalid.
