- Compatible Replacement & Soluții de upgrade
Original model is obsolete; two selection scenarios below:
Opţiune 1: Upgrade to ABB ACS380-04-09A5-4 (3 kW,9.5 O)
Avantaje: New-generation machinery drive, funcții îmbunătățite, 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.
Opţiune 2: Spare-part stock of original ACS355-03E-07A3-4
Avantaje: Montaj identic, wiring and parameters; direct drop-in replacement
Dezavantaje: Limited stock, high unit price, long lead-time; classified as obsolete legacy spare-part stock.
- Scenarii tipice de aplicare
OEM machinery supporting: transportoare, utilaje de ambalare, textile equipment, woodworking machines, food-beverage processing equipment, small-size pumps & fani, simple lifting mechanisms and general-purpose variable-speed applications.
- Note de selecție & Application Boundary Conditions
- Temperatura mediului ambiant: 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: aproximativ. 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) Frecvenţă Converter
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.
- Ambalare & Material-Handling Industry
Transportoare cu bandă, transportoare cu role, transportoare cu lanț, echipamente de sortare
Wrapping machines, case sealers, strapping machines, auxiliary palletizing mechanisms
Caracteristici: Frequent start-stop cycles, smooth speed regulation; STO safety function supports machine safety protection.
- Utilaje pentru prelucrarea lemnului
Wood cutting machines, șlefuitoare, multi-axis milling machines, saws
Material feed mechanisms for wood processing
Puncte forte: 0-600 Hz high-frequency output for high-speed spindles; on-board 8-step sequence programming reduces external PLC hardware requirement.
- Utilaje textile
Small-scale spinning & weaving auxiliary feeders, winding machines, sizing-machine auxiliary drives
Requirements: Cuplu stabil la viteză mică, tension-control capability; suitable for light-to-medium-duty winding tasks.
- Mâncare & Beverage Processing Equipment
Small mixing-tank drives, conveyor chains, filling-lines, labellers, mașini de sortat
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 & Fani (HVAC & Tratarea apei)
Process circulation pumps, water-supply pumps, small centrifugal fans, ventilatoare de evacuare
Remarcă: Pumps and fans belong to quadratic-torque loads. This drive is applicable; cu toate acestea, dedicated fan-pump drives are preferred for large-capacity energy-saving projects.
- Materiale plastice & Rubber Machinery Auxiliary Equipment
Feeder units, benzi transportoare, 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.
- Manipularea materialelor & 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 (Capcanele de selecție)
- 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 (de ex. 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.
