Auxiliary Reference Operation Ex #1
Keypad Frequency Setting is Main Frequency and V1 Analog Voltage is Auxiliary
Frequency
•
Main frequency: 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)].
Setting * 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.
