Auxiliary Reference Operation E.g.
#1
Keypad Frequency Setting is Main Frequency and V1 Analog Voltage is Auxiliary
Frequency
• Main frequency: Keypad (operation frequency 30 Hz)
• Maximum frequency setting (dr.20): 400 Hz
• 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 output
Example: an input voltage of 6V 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)].

M[z]+(G[%]*A[Hz])
30 Hz(M)+(50%(G)x36 Hz(A))=48 Hz

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
