The auxiliary command frequency is turned off when the terminal input (Px) set to
“

is on.
Auxiliary Reference Operation Ex #1
Keypad Frequency Setting is Main Frequency, and V1 Analog Voltage is Auxiliary Frequency
•
Main frequency (DRV-07): Keypad (operation frequency 30 Hz)
•
Maximum frequency setting (DRV-20): 400 Hz
•
Auxiliary frequency setting (BAS-01): V1 [Display by percentage (%) or auxiliary frequency (Hz)
depending on the operation setting condition]
•
Auxiliary reference gain setting (BAS-03): 50%
•
IN-01

32: Factory default
Example: An input voltage of 6 V is supplied to V1, and the frequency corresponding to 10 V is 60
Hz. The table below shows the auxiliary frequency A as 36 Hz [=60 Hz X (6 V/10 V)] or 60% [= 100%
X (6 V/10 V)].

Calculating final command frequency**
0 M[Hz]+(G[%]*A[Hz])
30 Hz(M)+(50%(G)x36 Hz(A))=48 Hz
1 M[Hz]*(G[%]*A[%])
30 Hz(M)x(50%(G)x60%(A))=9 Hz
2 M[Hz]/(G[%]*A[%])
30 Hz(M)/(50%(G)x60%(A))=100 Hz
3 M[Hz]+{M[Hz]*(G[%]*A[%])}
30 Hz(M)+{30[Hz]x(50%(G)x60%(A))}=39 Hz
4 M[Hz]+G[%]*2*(A[%]-50[%])[Hz]
30 Hz(M)+50%(G)x2x(60%(A)
–
50%)x60 Hz=36 Hz
5 M[HZ]*{G[%]*2*(A[%]-50[%])}
30 Hz(M)x{50%(G)x2x(60%(A)
–
50%)}=3 Hz
6 M[HZ]/{G[%]*2*(A[%]-50[%])}
30 Hz(M)/{50%(G)x2x(60%
–
50%)}=300 Hz
7 M[HZ]+M[HZ]*G[%]*2*(A[%]-50[%]) 30 Hz(M)+30 Hz(M)x50%(G)x2x(60%(A)
–
50%)=33 Hz
* M: Main frequency reference (Hz or rpm)/G: Auxiliary reference gain (%)/A: Auxiliary frequency
reference (Hz or rpm) or gain (%).
** If the frequency setting is changed to rpm, it is converted to rpm instead of Hz.
