Cx2000 AC Drive
 I7 ~ I10: the input voltage range and corresponding frequency of V1 terminal can be set.
 Ex) when minimum (+) input voltage is 2V with corresponding frequency 10Hz and Max voltage is 8V with
run req. 50Hz.
 Wire the terminals as shown below
Terminal AI setting frequency(dial J1 to terminal I): input 0 ~ 20[mA]
