Aux Ref
Gain
Adjust the size of the input (bA.03 Aux Ref Src) configured for auxiliary frequency.
In.65–71
Px
Define Set one of the multi-function input terminals to 40(dis Aux Ref) and turn it on to disable
the auxiliary frequency reference. The inverter will operate using the main frequency
reference only.
F(M,A,G)
Main frequency M
Auxiliary frequency A
Calculated frequency
Auxiliary frequency command does not work if
the multi-function terminals (In.65-71) are set to
40(disable aux. reference).
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.03): V1[Display by percentage(%) or auxiliary frequency (Hz)
depending on the operation setting condition]
•
Auxiliary reference gain setting (bA.05): 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)].
Setting* Calculating final command frequency**
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
