Setting Frequency by Current Reference Input
When setting frequency by inputting current reference (4-20mA or 0-20mA) from the control circuit terminal FR, switch the DIP switch SW1 on the control circuit board to “I” side.
SW1 is accessed by removing the digital operator.
NOTE
Never input voltage reference to control circuit terminal FR when DIP switch
SW2 is switched to “I” side. This could damage the inverter.

Current reference selection
After changing DIP switch (V/I switch of SW2) to the “I” side, PRESS PRGM on the digital operator, then set the following parameters.
Current reference (4-20mA) parameter n004=3
Current reference (0-20mA) parameter n004=4
Press the digital operator keys to run or stop the inverter. Switch run and stop direction by setting F/R LED.
Set frequency by the analog current signal
[0-100% (max frequency)/4-20mA] connected to the control circuit terminal.
Set run/stop and FWD/REV run with switching device connected to the control circuit terminal.
Multi-function input terminals S1 and S2 are set to Forward run / STOP (n050 = 1) and
Reverse run/stop (n051 = 2) respectively.
Set frequency by the analog current signal
[0-100% (max. frequency)/4-20mA] connected to the control circuit terminal.
Frequency reference gain (n060)/bias (n061) can be set even when current reference input is selected. For details, refer to “Adjusting frequency setting signal” on page 81.
