Compatible Replacement & アップグレードソリューション

Original model is obsolete; two selection scenarios below:

オプション 1: Upgrade to ABB ACS380-04-09A5-4 (3 kW,9.5 あ)

利点: New-generation machinery drive, 充実した機能, 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.

オプション 2: Spare-part stock of original ACS355-03E-07A3-4

利点: 同一の取り付け, 配線とパラメータ; direct drop-in replacement

短所: Limited stock, high unit price, long lead-time; classified as obsolete legacy spare-part stock.

典型的なアプリケーションシナリオ

OEM machinery supporting: コンベア, 包装機械, textile equipment, woodworking machines, food-beverage processing equipment, small-size pumps & ファン, simple lifting mechanisms and general-purpose variable-speed applications.

選定メモ & Application Boundary Conditions
周囲温度: 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: 約. 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) 頻度 コンバータ

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.

包装 & Material-Handling Industry

ベルトコンベア, roller conveyors, chain conveyors, sorting equipment

Wrapping machines, case sealers, strapping machines, auxiliary palletizing mechanisms

特徴: Frequent start-stop cycles, smooth speed regulation; STO safety function supports machine safety protection.

木工機械

Wood cutting machines, sanders, multi-axis milling machines, saws

Material feed mechanisms for wood processing

Strengths: 0-600 Hz high-frequency output for high-speed spindles; on-board 8-step sequence programming reduces external PLC hardware requirement.

繊維機械

Small-scale spinning & weaving auxiliary feeders, 巻線機, sizing-machine auxiliary drives

要件: Stable low-speed torque, tension-control capability; suitable for light-to-medium-duty winding tasks.

食べ物 & Beverage Processing Equipment

Small mixing-tank drives, conveyor chains, filling-lines, ラベラー, sorting machines

注記: The drive must be installed inside electrical cabinets. Direct exposure to wash-down / humid environments is not allowed; proper cabinet environmental protection is required.

パンプス & ファン (空調設備 & 水処理)

Process circulation pumps, water-supply pumps, small centrifugal fans, 排気ファン

述べる: Pumps and fans belong to quadratic-torque loads. This drive is applicable; しかし, dedicated fan-pump drives are preferred for large-capacity energy-saving projects.

Plastics & Rubber Machinery Auxiliary Equipment

Feeder units, コンベヤーベルト, 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.

マテリアルハンドリング & 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 (Selection Pitfalls)

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 (例えば. 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.
