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])}.
