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.03): I2 [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 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])}.
