Figure 5-60 Frequency Setting Via VCI-5 or CCI-5
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 Figure5-61.

Figure 5-61 PULSE-0.5 × F1.03 As Freq. Input
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.
F9.03: initial value of digital auxiliary reference
It is valid when F9.01=1~3. It is the initial setting of any of the
3 method.
F9.04: digital auxiliary reference control
It is valid when F9.01=1~3. See Figure 5-62.

One's place of F9.04
0: save the auxiliary freq. at power off
The auxiliary frequency will be saved in F9.03, and the sign
of the freq. saved in F9.04.
1: not save the auxiliary freq. at power off
Ten's place of 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.

F9.05 defines how to calculate the preset frequency. Refer to
Figure 5-57.
0: disabled
No additional summing operation to the sum of main freq.
and auxiliary freq. See Figure 5-58.

Preset freq. f4=f3+F0.05 × (F9.06-100%)
2: regulate based on current output freq. (F005)
Preset freq.f4=f3+f3 × (F9.06-100%) =f3 × F9.06
