🔄 Cross-model & Riferimento sostitutivo

1. Stesso potere & same platform: ATV650D45N4E (version with disconnect switch)
2. Stesso potere, IP20 cabinet-mounted version: ATV630D45N4 (Altivar630, IP20, installazione dell'armadio)
3. Legacy replacement: ATV71HD45N4 (interrotto; program migration requires parameter mapping and communication register adjustment)

📎 Standard Optional Accessories

Unità freno & resistenza freno (high-inertia loads, fast stop)

Reattore di ingresso, output dv/dt filter, sine-wave filter (long motor cables)

Digital/analog I/O expansion cards, encoder cards (closed-loop vector control)

Communication cards: Profinet, Ethernet/IP (on-demand expansion)

Remote keypad, EADM tool (firmware upload/download, parameter backup)

⚠️ Key Selection Notes

For heavy-duty applications (frantoi, reciprocating pumps, frequent start-stop), size strictly according to HD 37kW / 74.5UN; do not use the 45kW ND rating directly.

IP55 only provides splash-proof & dust-proof protection, not immersion protection; outdoor installation requires extra sun & rain housing.

Mainstream firmware version for this model: V4.6IE47.

📋 Troubleshooting – Common Faults

Overcurrent OC: Motor short-circuit to ground, cavo danneggiato, rotore bloccato, incorrect auto-tuning

Overheating OH: Filtro intasato, failed cooling fan, temperatura ambiente eccessiva, insufficient derating margin

Communication dropout: IP conflict, improper cable shielding & messa a terra, wrong ring network configuration on dual Ethernet ports

Interferenze EMC: Motor cable exceeds C2/C3 length limit; add output filter

ATV650D45N4 ↔ ATV630D45N4 ↔ ATV71HD45N4 Migration Comparison Table

Core conclusion: ATV630 / ATV650 share the same Altivar Process ATV600 platform; parameters and communication registers are highly compatible. ATV71 belongs to the legacy platform; configuration files cannot be imported directly. Control architecture, PZD telegram, I/O assignment and fault codes all need remapping.

1. Migration Risk Checklist (Per scenario)

Scenario 1: ATV630D45N4 ↔ ATV650D45N4 (Same Platform Replacement – Lowest Risk)

✅ SoMove can upload/download parameters, macros and Com Scanner tables directly

✅ Modbus TCP registers, controllare & status words are fully consistent; no PLC program changes required

⚠️ Items to verify:

1. Dimensioni di montaggio, cutout sizes and cable entry direction (ATV650 is deeper and heavier)
2. Heat dissipation space and temperature derating curve for IP55 units
3. Copertura terminale, earthing and shielding scheme
4. Selection between standard version and disconnect-switch version (ATV650D45N4E)

Scenario 2: ATV71HD45N4 → ATV630D45N4 / ATV650D45N4 (Cross-platform Upgrade – High Risk)

❌ Never import ATV71 configuration files directly; incompatibility error will occur

✅ Standard Migration Procedure

1. Back up ATV71 parameters via old SoMove; photograph all wiring, terminal assignments and communication card models
2. Record PLC PZD telegram, every bit of control word, and fault acquisition logic
3. Restore factory settings on the new Altivar Process drive and select the matching application macro (Pump/Fan / Coppia)
4. Enter motor nameplate data and run auto-tuning
5. Re-map DI/AO and relay functions; do not copy ATV71 terminal function definitions directly
6. Reconfigure Com Scanner communication table and rewrite PLC program (remap control & status words)
7. Verify ramp times, current limits, Parametri PID, fault management and auto-restart logic
8. Test jog operation with no load, then commission with full load

Insidie ​​frequenti:

1. Brake circuit: ATV71 has built-in brake transistor while ATV630/650 do not. Missing brake unit causes DC bus overvoltage (dCF) during deceleration.
2. Capacità di sovraccarico: ATV71 45kW HD current is higher; heavy-duty loads will trigger OL overload faults easily.
3. Communication words: Many projects copy ATV71 PZD directly, leading to no drive response or wrong rotation direction.
4. Digital input quantity: If DI7/DI8 were used on ATV71, an I/O expansion card is required since ATV630/650 only have 6 onboard DI channels.
