Auxiliary Reference Operation Ex #1
Keypad Frequency Setting is Main Frequency and V1 Analog Voltage is Auxiliary
Frequency
• Main frequency: Keypad (operation frequency 30Hz)
• Maximum frequency setting (dr.20): 400Hz
• Auxiliary frequency setting (bA.01): V1[Display by percentage(%) or auxiliary frequency
(Hz) depending on the operation setting condition]
• Auxiliary reference gain setting (bA.03): 50%
• In.01–32: Factory default
Example: an input voltage of 6V is supplied to V1, and the frequency corresponding to 10V is
60Hz. The table below shows the auxiliary frequency A as 36Hz[=60Hz X (6V/10V)] or 60%[=
100% X (6V/10V)].

0
M[Hz]+(G[%]*A[Hz])
30Hz(M)+(50%(G)x36Hz(A))=48Hz
1
M[Hz]*(G[%]*A[%])
30Hz(M)x(50%(G)x60%(A))=9Hz
2
M[Hz]/(G[%]*A[%])
30Hz(M)/(50%(G)x60%(A))=100Hz
3
M[Hz]+{M[Hz]*(G[%]*A[%])}
30Hz(M)+{30[Hz]x(50%(G)x60%(A))}=39Hz
4
M[Hz]+G[%]*2*(A[%]-50[%])[Hz]
30Hz(M)+50%(G)x2x(60%(A)–
50%)x60Hz=36Hz
5
M[HZ]*{G[%]*2*(A[%]-50[%])}
30Hz(M)x{50%(G)x2x(60%(A)–50%)}=3Hz
6
M[HZ]/{G[%]*2*(A[%]-50[%])}
30Hz(M)/{50%(G)x2x(60%–50%)}=300Hz
7
M[HZ]+M[HZ]*G[%]*2*(A[%]-50[%])
30Hz(M)+30Hz(M)x50%(G)x2x(60%(A)–
50%)=33Hz
*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.
