Keypad Frequency Setting is Main Frequency and I2 Analog Voltage is Auxiliary

Frequency

• Main frequency: Keypad (operation frequency 30 Hz)

• Maximum frequency setting (dr.20): 400 Hz

• Auxiliary frequency setting (bA.01): I2[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 current of 10.4 mA is applied to I2, with the frequency corresponding

to 20 mA of 60 Hz. The table below shows auxiliary frequency A as 24 Hz (=60[Hz] X

{(10.4[mA]-4[mA])/ (20[mA] - 4[mA])} or 40% (=100[%] X {(10.4[mA] - 4[mA])/ (20[mA] -

4[mA])}.

Calculating final command frequency

M[Hz]+(G[%]*A[Hz])

30 Hz(M)+(50%(G)x24 Hz(A))=42 Hz

M[Hz]*(G[%]*A[%])

30 Hz(M)x(50%(G)x40%(A))=6 Hz

M[Hz]/(G[%]*A[%])

30 Hz(M)/(50%(G)x40%(A))=150 Hz

M[Hz]+{M[Hz]*(G[%]*A[%])}

30 Hz(M)+{30[Hz]x(50%(G)x40%(A))}=36 Hz

M[Hz]+G[%]*2*(A[%]-

50[%])[Hz]

30 Hz(M)+50%(G)x2x(40%(A)–50%)x60 Hz=24

M[HZ]*{G[%]*2*(A[%]-50[%])

30 Hz(M)x{50%(G)x2x(40%(A)–50%)} =

-3 Hz(Reverse)

M[HZ]/{G[%]*2*(A[%]-50[%])}

30 Hz(M)/{50%(G)x2x(60%–40%)} = -300

Hz(Reverse)

M[HZ]+M[HZ]*G[%]*2*

(A[%]-50[%])

30 Hz(M)+30 Hz(M)x50%(G)x2x (40%(A)–50%)=

27 Hz

* M: Main frequency reference/ G: Auxiliary reference gain (%)/ A: Auxiliary

frequency reference (Hz or rpm) or gain (%)
