Main-Power Circuit
| Terminal | Funcţie | Observații |
| L1/L2/L3 | 3‑phase 380‑500 V input | Do NOT swap with U/V/W motor terminals |
| U/V/W | Motor output | Connect to 3‑phase motor; shielded cable recommended |
| BR+ / BR‑ | Rezistenta de frana | For built‑in brake chopper; connect brake resistor here, DO NOT connect to DC‑bus terminals |
| +DC /‑DC | DC‑link bus | Used for common‑DC‑bus multi‑drive systems; leave unconnected for standard operation |
| PE | Pământ protector | Reliable earthing mandatory |
Cable sizing suggestion for 55 kW: power-supply cable ≥16 mm²; motor cable ≥16 mm²; brake-resistor cable ≥10 mm².
Control-circuit mandatory connections (fault or drive-inhibited if ignored)
- STO Safe-Torque-Off: short terminal 12 la 37. Without short-circuit, inverter output is inhibited. For external safety circuits, wire safety contacts in series.
- Coast-to-stop terminal 27 is factory-active: if coast-to-stop is not needed: set parameter 5-12 = 0 (no function). To retain coast-to-stop: short 12-27.
- Terminale 12/13: internal +24 V output (max. 200 mA); terminal 20 = digital-input common ground.
- Analogue inputs: 53 (0-10 V voltage); 54 (4-20 mA). Hardware dip-switches select voltage / modul curent.
- Terminale 68/69: RS485 Modbus-RTU; 68 = A, 69 = B.
Example terminal-based start-stop logic
18 (DIN): Început (parameter 5-10 = Start)
19 (DIN): Verso (parameter 5-11 = Reverse)
54: 4-20 mA frequency reference
Releu 01-02-03: configurable for Run / Fault signalling.
Practical advice: power-up without motor first and check I/O status. For commissioning, decouple motor coupling and test at low speed.
- Factory-reset procedures
Method 1: Recommended Initialisation (retains run-hours and communication settings)
- Main Menu → 14-Special Functions → 14-22 Modul de operare
- Selecta 2 Initialisation → press OK
- Disconnect main supply; wait until panel fully dark; re-apply power
- A80 “Drive initialised” informational message appears (not a fault); press Reset.
Method 2: Full Hard Initialisation (all parameters cleared)
- Power-off; wait for panel to extinguish.
- Hold Status + Main Menu + OK keys together, then switch-on main supply.
- Keep holding for 5 s then release. Full factory reset completes on power-on.
Parameter backup tip: 0-50 LCP Copy → select 1 Copy all parameters to LCP. The panel can store parameters for download to identical units. Do NOT copy parameters across different power ratings.
- Key Commissioning Parameters (unit fitted with built-in brake chopper)
| Parametru | Descriere | Suggested Setting |
| 1‑01 | Motor Control Principle | VVCplus / Flux Vector. Asynchronous motor: VVCplus; high low‑speed torque: select Flux Vector |
| 1‑20~1‑26 | Motor Nameplate Data | Enter nameplate power, Voltaj, actual, frecvenţă, speed exactly |
| 1‑29 | AMA Motor Auto‑Tune | Static AMA; perform with mechanical load decoupled |
| 2‑10 | Brake Function | Enable built‑in brake chopper → 1 Permite |
| 2‑11 | Brake‑resistor Ohmic Value | Input actual resistor value for thermal protection |
| 2‑12 | Brake‑resistor Power Rating | Input resistor power rating to activate resistor thermal‑model protection |
| 3‑41/3‑42 | Ramp up‑/down‑time | Lengthen deceleration for high‑inertia loads to avoid AL‑16 over‑voltage |
| 5‑10/5‑11 | Digital‑Input Functions | Configure start‑stop, direction commands |
Brake-chopper warning: short-circuited or under-rated low-ohm resistors will destroy the brake chopper. Always populate 2-11 & 2-12 for thermal protection.
- Incoming-inspection checklist for second-hand FC-302-55 kW (C4 frame)
Inspecție vizuală
- PCB-uri: check for water ingress, corrosion or burn marks. Examine cooling air-path and fan for heavy dust. Manually spin fan for free rotation, no sticking.
- Borne de alimentare: check for arcing / burn damage. Verify nameplate model string: FC-302P55KT5E20H2B G……, order No. 131F7151.
- Test all keys on LCP102 graphical panel.
Power-off static multimeter tests (full DC-bus discharge mandatory)
- Rectifier stage: measure forward / reverse diode drop L1/L2/L3 against +DC /-DC.
- IGBT stage: measure U/V-W versus +DC, -DC. Three-phase readings must be well-matched; large deviation indicates module failure.
- Brake circuit: test BR+ / BRchopper transistor for short-circuit breakdown.
- Confirm no control-terminal-to-earth short-circuits.
No-load power-on test (motor disconnected)
- Pornire, verify no active faults. Read run-hours 15-00; inspect fault-history log 15-30.
- Perform factory reset then AMA auto-tune. Run 0-50 Hz no-load; check three-phase output-voltage balance. Unbalance points to IGBT / drive-board damage.
- Brake-chopper functional test: set short deceleration time to induce regeneration; observe DC-bus voltage rise and brake activation.
- STO test: deschide 12-37 link → STO fault appears; re-short to clear.
- Full point-by-point test for all digital inputs and relay outputs.
Motor-coupled test
Disconnect mechanical load. Run motor, verify balanced 3-phase current, no vibration or abnormal noise. High-overload 160 % / 1 min test: exercise with caution.
Common failure items: fan wear, current-sensor drift, brake-chopper damage, STO safety-circuit faults, aged electrolytic capacitors. Typical alarms: AL13 Over-current, AL16 Over-voltage, AL29 Heatsink Over-temp, AL-8 STO fault.
- Domestic Chinese-manufactured alternative selection (55 kW high-performance vector, 380-500 V)
FC-302 features: flux-vector control, asynchronous & PMSM support, built-in DC-link reactor, built-in brake chopper, expandable fieldbus cards, STO Safe-Torque-Off. Verify feature-match before substitution.
| Marca & Model | Key Matching Features | Observații |
| Inovaţie MD380‑T55‑G | Open‑ / vector în buclă închisă; STO‑capable; Profinet / EtherCAT expandable; brake‑unit optional | General‑purpose industrial constant‑torque. Confirm brake‑chopper availability for your project. |
| INVT CHV190‑055G‑4 | Vector de înaltă performanță; asynchronous / PMSM support; expandable fieldbus; STO | For extruders, transportoare, mixere; brake unit built‑in or external option |
| Delta CH2000‑55 kW | Flux‑vector control; STO safety; expandable communication cards | Heavy‑duty applications, good substitution compatibility |
Substitution caveats:
- Original FC-302 has integrated DC-link reactor. Many domestic alternatives omit this; add external DC-reactor for sites with high-harmonic-grid conditions.
- Original unit includes built-in B-option brake chopper. Confirm alternative unit has on-board brake chopper or plan for external brake unit.
- STO Safe-Torque-Off may be an option card for some domestic drives; do not overlook for safety-related machinery.
- Communications: base unit has no fieldbus card (MCA120 Profinet retrofittable). Confirm bus-interface requirements for replacement drive.
- Quick fault-troubleshooting guide
- Drive will not run; alarm AL-8: inspect STO loop (12-37 scurtcircuit / safety-contact continuity).
- Coast-to-stop-related alarm: either short 12-27 or set parameter 5-12 to no-function.
- Deceleration over-voltage AL16: ① extend deceleration ramp time; ② confirm brake chopper enabled; ③ validate brake-resistor value & puterea nominală.
- AL29 Heatsink Over-temperature: clean dust build-up, inspect fan, reduce carrier-frequency, limit sustained ambient temperature ≤40 °C.
