Closed when either FWD/REV Run Command is input or voltage is output from the Inverter. Closed when the set frequency agrees with Inverter output frequency. Closed when Inverter output frequency is less than minimum output frequency. Output frequency Frequency Detection Level (n095) Output frequency Frequency Detection Level (n095) Closed when an alarm has been detected. Closed when LOCAL is selected for the LOCAL/REMOTE selection. Closed when an Inverter fault is not detected, and operation is ready. page - 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Frequency agree Zero speed Frequency detection 1 Frequency detection 2 Overtorque detection, NO contact output Overtorque detection, NC contact output Undertorque detected, NO contact output Undertorque detected, NC contact output Minor fault Base blocked Operating mode Inverter operation ready Fault retry UV 125 82 82 81 81 185 185 - 124 6 Programming Features Setting 16 17 18 Name Reverse run Speed search Data output from communications Description Closed during reverse run.

SW2 SW2 V I NOTE Never input a voltage reference to control circuit terminal FR when DIP switch SW2 is switched to the "I" side. The Inverter might be damaged. 126 6 Programming Features Current Reference Selection After changing the DIP switch (V-I switch of SW2) to the "I" side, press PRGM on the Digital Operator, then set the following constants. Current reference (4 to 20 mA): constant n004 = 3 Current reference (0 to 20 mA): constant n004 = 4 · Setting: n003 = 0 IM Press the Digital Operator keys to run or stop the Inverter. Switch FWD and REV run by setting the F/R LED. Set the frequency by the analog current signal [0 % to 100 % (max.
