Important Clarification

There is no Mitsubishi FRN0018G2S4C model.

FRN0018G2S4C is a Fuji Electric FRENICMEGA G2S inverter. Mitsubishi inverters use the prefix FR, 例えば. FRD740, FRA840. Mitsubishi has no FRNprefixed models. It is a common industry misnomer to call Fuji FRNseries units “Mitsubishi”.

Frequently Confused: Mitsubishi Peerrating Reference

If you intend to compare with Mitsubishi equivalentpower inverter, the counterpart is FRA8400170460 (5.5 kW heavyduty). Comparison table below:

Onsite Identification Tips

1. Nameplate marking: Fuji displays FRENICMEGA; Mitsubishi displays Mitsubishi Electric
2. Model rule: FRN = Fuji; FR= Mitsubishi. Wrong ordering prefix will result in wrong delivery.
3. Keypad layout: G2S keypad layout differs completely from Mitsubishi A840 series.

交換リマインダー

Direct dropin swap from Fuji G2S to Mitsubishi A840 is impossible. 端子, parameters and motortuning logic differ; full recommissioning is required.

Parameter Setting Procedure for Fuji FRN0018G2S4C (FRENICMEGA G2S)

Keypadbutton description:

PROG/RESET: Enter parameter menu / fault reset

FUNC/DATA: Enter functioncode menu / save parameters

▲ ▼: Scroll functioncodes / modify values

MODE: Toggle monitor screens (頻度, 現在, 電圧, 障害記録)

前輪駆動, REV, 停止: Keypad forward, 逆行する, stop commands

1. Standard Commissioning Sequence (Field Workflow)

Step 1: Factory Reset

1. Press【PROG/RESET】to enter parameter mode
2. Locate F00 (Initialization), set value =1
3. Press【FUNC/DATA】to confirm, powercycle the inverter. All parameters revert to factory defaults.

⚠️Important: Perform reset for new units, motor replacement, or abnormal commissioning status.

Step 2: Input Motornameplate Data (Pgroup motor parameters)

Input exact values from the motor nameplate. Mandatory for vectorcontrol operation.

Step 3: Motor Autotuning (Mandatory for vectorcontrol, to achieve 200% @0.3 Hz torque)

1. Static autotuning (Fieldfriendly; no mechanical disconnection required)

Set P07=1 (Static autotuning), press【FUNC/DATA】, display shows TUNE

Press【FWD】to start tuning; wait dozens of seconds, process terminates automatically.

2. Rotational autotuning (Motor must run unloaded; best tuning result)

Set P07=2, press【FWD】. Motor will run at low speed for learning.

警告: For rotational autotuning, motor must be mechanically decoupled to avoid injury risk.

Step 4: Runcommand & Frequencyreference Source Configuration

✅ Keypad control (Keypad start/stop + keypad frequency adjustment)

F02 Runcommand source =0 (Keypad buttons)

F01 Frequencyreference source =0 (Keypad ▲▼ keys)

✅ Terminal control (Fieldmostcommon: externalterminal startstop, analog speed reference)

F02 =1: Terminal runcommand (Short FWD to COM for forward rotation; short REV to COM for reverse rotation)

F01 Frequencyreference source:

1: Terminal 12 (010 V voltage reference)

2: Terminal C1 (420 mA current reference); set mainboard DIPswitch SW8 to C1 position.

✅ RS485 Communication control

F02 =2: Communication runcommand; F01=4: Communication frequency reference.

Step 5: Basic Fgroup Operating Parameters

This unit has builtin braking transistor. If OV overvoltage faults occur during deceleration, connect external braking resistor between P(+) and DB terminals.

1. Quicksetup for Frequentlyused Functions
2. Multispeed operation (Select preset speeds via Xterminals)
3. Set E01(X1 terminal)=1(SS1); E02(X2 terminal)=2(SS2)
4. C05C19: Multispeed frequency 115, configure each presetspeed value.

Combination logic of X1/X2 terminals supports up to 15 プリセット速度. Multispeed has higher priority than analog reference.

2. PID Control (Constantpressure watersupply, constanttension applications)
3. J01=1: Enable PID
4. J02: Select PID setpoint source
5. J03J05: P/I/D gain parameters; enable J30 PID autotuning for automatic gain optimization.
6. STO SafeTorqueOff (Hardware safety circuit)

Terminals TH1TH2: Both terminals must be shortcircuited to enable inverter output. Open STO circuit directly blocks power output without alarm code.

Ⅲ. パラメータのバックアップ & Upload/Download

Requires TPA2SW operator keypad:

1. Read parameters from old inverter: Enter menu Y98 to upload parameters to keypad memory.
2. Write parameters to new inverter: Set Y99 for download; bulkimport all parameters without manual entry.
3. Controlmode Selection for Different Load Types
4. コンベヤ, 押出機, ホイスト (Heavyduty constanttorque)

F42 Controlmode =1【Sensorless Vector 2】. Complete motor autotuning for high lowspeed torque.

2. ファン & パンプス (Lightduty squarelaw load)

F42 =0: V/F制御. Motor autotuning is unnecessary.

3. Highspeed spindle applications (Highfrequency output)

Increase F03 maximumoutputfrequency setting, run under V/F mode. Respect motor maximumspeed rating.

1. Common Commissioningfault Troubleshooting
2. OC Overcurrent: Doublecheck P03 motorcurrent setting; confirm autotuning completion; increase accelerationtime value.
3. OV Overvoltage: Decelerationtime too short; increase F08 decelerationtime; fit braking resistor for highinertia loads.
4. Insufficient torque: Verify correctness of Pgroup motorparameters, finish autotuning, activate sensorlessvector mode.
5. 電磁妨害: 4C model has builtin EMC filter; use shielded motor cables; reliable earthing for inverter and motor.
6. Practical Operation Notes
7. After modifying parameters, press FUNC/DATA to save; otherwise settings will be lost after poweroff.
8. After motor replacement, reenter P01P06 and rerun autotuning.
9. Toggle HHDHeavyduty / HNDLightduty mode via F44: 0 = HHD Heavyduty 5.5 kW; 1 = HND Lightduty 7.5 kW.
