- Sostituzione compatibile & Soluzioni di aggiornamento
Original model is obsolete; two selection scenarios below:
Opzione 1: Upgrade to ABB ACS380-04-09A5-4 (3 kW,9.5 UN)
Vantaggi: New-generation machinery drive, funzioni migliorate, hardware STO supported, parameter migration tool available
⚠️ Notice: Terminal layout and cabinet mounting cutouts are NOT fully compatible. Cabinet modification is required. I/O definitions differ. Direct plug-and-play replacement is impossible. Rewiring, parameter conversion and commissioning are mandatory.
Opzione 2: Spare-part stock of original ACS355-03E-07A3-4
Vantaggi: Montaggio identico, cablaggio e parametri; direct drop-in replacement
Svantaggi: Limited stock, high unit price, long lead-time; classified as obsolete legacy spare-part stock.
- Scenari applicativi tipici
OEM machinery supporting: trasportatori, macchine per l'imballaggio, attrezzature tessili, woodworking machines, food-beverage processing equipment, small-size pumps & tifosi, simple lifting mechanisms and general-purpose variable-speed applications.
- Note sulla selezione & Application Boundary Conditions
- Temperatura ambiente: Full-rating operation from 0 °C to +40 °C; derating required above 40 °C. Condensation, corrosive gas and heavy dust are prohibited. IP20 rating permits cabinet-only installation; direct field exposure is forbidden.
- This unit is factory-fitted with EMC filter. If input line reactor is added, ensure proper filter earthing.
- For heavy-duty cycles with frequent shock loading, select according to actual motor operating current instead of nominal power rating. If actual motor current exceeds 7.3 A, select the next higher drive frame size.
- Brake chopper is built-in; brake resistor must be externally fitted. Select brake resistor strictly per manual specifications. Never short-circuit BR terminals.
- For valid STO safety function in production operation, both STO channels shall be wired; single-channel short-circuit is prohibited.
- Important Maintenance Guidelines
Service life of R1-frame cooling fan: ca. 3 years; fan replacement is recommended upon expiry.
Retorque power terminals every 6 years.
Annual functional verification test for STO safety function is recommended.
Application Fields of ABB ACS355-03E-07A3-4 (3 kW) Frequenza Convertitore
This is a compact OEM-oriented vector drive with IP20 cabinet-mount rating. It comes with built-in STO Safe Torque-Off, integrated EMC filter and built-in brake chopper. It targets general-purpose variable-speed control for small-to-medium-power stand-alone OEM machinery, and is not intended for heavy-duty continuous high-power drive cycles.
- Confezione & Material-Handling Industry
Trasportatori a nastro, trasportatori a rulli, chain conveyors, attrezzature per lo smistamento
Wrapping machines, sigillanti di casse, macchine reggiatrici, auxiliary palletizing mechanisms
Caratteristiche: Frequent start-stop cycles, smooth speed regulation; STO safety function supports machine safety protection.
- Macchine per la lavorazione del legno
Wood cutting machines, levigatrici, multi-axis milling machines, saws
Material feed mechanisms for wood processing
Punti di forza: 0-600 Hz high-frequency output for high-speed spindles; on-board 8-step sequence programming reduces external PLC hardware requirement.
- Macchinari tessili
Small-scale spinning & weaving auxiliary feeders, macchine avvolgitrici, sizing-machine auxiliary drives
Requisiti: Stable low-speed torque, tension-control capability; suitable for light-to-medium-duty winding tasks.
- Cibo & Beverage Processing Equipment
Small mixing-tank drives, conveyor chains, filling-lines, etichettatrici, macchine selezionatrici
Nota: The drive must be installed inside electrical cabinets. Direct exposure to wash-down / humid environments is not allowed; proper cabinet environmental protection is required.
- Pompe & Tifosi (HVAC & Trattamento delle acque)
Process circulation pumps, water-supply pumps, small centrifugal fans, ventilatori di scarico
Osservazione: Pumps and fans belong to quadratic-torque loads. This drive is applicable; Tuttavia, dedicated fan-pump drives are preferred for large-capacity energy-saving projects.
- Plastica & Rubber Machinery Auxiliary Equipment
Feeder units, nastri trasportatori, small extruder auxiliaries, take-up & pay-off mechanisms
⚠️ NOT recommended for main injection-molding pump drives: Severe shock-loading exceeds the drive’s overload margin.
- Movimentazione dei materiali & Light Lifting Equipment
Light-duty elevators, auxiliary travelling mechanisms for small hoists, small lifting platforms
❗Critical boundary condition: For lifting applications, external brake resistor must be fitted and brake chopper enabled. Operation without brake resistor for lowering loads is strictly forbidden.
- General-Purpose Machine-Tools & Small Processing Equipment
Small grinders, feed drives, small spindle drives.
❌ Non-applicable Conditions (Insidie della selezione)
- Outdoor direct installation (IP20; cabinet-mount only).
- Direct exposure to corrosive atmosphere, heavy conductive dust, condensation or moisture.
- Heavy-shock high-duty-cycle main drives (per esempio. main injection-molding pumps, large winches).
- Field wall-mount installation requiring IP54 / IP65 high-protection rating.
Unit Application Matching Key Points
ACS355-03E-07A3-4 (3 kW /7.3 A) is intended for continuous rated load ≤3 kW motors. 150% overload for 1 min is specified for standard OEM machinery. For applications with frequent shock overload, select one power frame higher.
