Auxiliary Reference Operation Ex #2
Keypad Frequency Setting is Main Frequency and I2 Analog Voltage is Auxiliary Frequency
• Main frequency: Keypad (Operation frequency 30Hz)
• Maximum frequency setting (dr.20): 400Hz
• 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
Example: an input current of 10.4mA is applied to I2, with the frequency corresponding to 20mA of
60Hz. The table below shows auxiliary frequency A as 24Hz(=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])}.

M[HZ]/{G[%]*2*(A[%]-50[%])}
30Hz(M)/{50%(G)x2x(60%–40%)} = -300Hz(Reverse)

M[HZ]+M[HZ]*G[%]*2*(A[%]-50[%])
30Hz(M)+30Hz(M)x50%(G)x2x (40%(A)–50%)=27Hz

**If the frequency setting is changed to rpm, it is converted to rpm instead of Hz.
Auxiliary Reference Operation Ex #3
V1 is Main Frequency and I2 is Auxiliary Frequency
• Main frequency: V1 (frequency command setting to 5V and is set to 30Hz)
• Maximum frequency setting (dr.20): 400Hz
• Auxiliary frequency (bA.01): I2[Display by percentage (%) or auxiliary frequency (Hz) depending
on the operation setting condition]
• Auxiliary reference gain (bA.03): 50%
• In.01–32: Factory default
Example: an input current of 10.4mA is applied to I2, with the frequency corresponding to 20mA of
60Hz. The table below shows auxiliary frequency Aas 24Hz(=60[Hz]x{(10.4[mA]-4[mA])/(20[mA]-
