✅ Supplementary Notes

Parameters cannot be copied directly between ACS350 and ACS355; parameter files must be re-uploaded/downloaded. Although the keypad is interchangeable, firmware and parameter groups differ. Always compare the original parameter list during replacement.

ABB ACS350-03E-23A1-4 (11 кВт) Engineering Application Cases

Описание: The ACS350 is a legacy OEM machinery drive with built-in EMC filter, встроенный тормозной прерыватель, embedded sequence programming and native Modbus RTU, идеально подходит для нагрузок с постоянным крутящим моментом. Below are the most common field applications for this power rating, including process description, control scheme, key parameters, risk points and retrofit notes.

Случай 1: Main Belt Conveyor on Packaging Lines (Classic Constant-Torque Application)

Нагрузка: 11 kW conveyor motor for bulk material handling; smooth start/stop, anti-jam and speed synchronization between upstream/downstream sections required.

Схема управления

Режим управления: Безсенсорное векторное управление (99.04=1)

Speed reference: AI1 receives potentiometer/PLC analog signal; digital inputs select multi-speed preset (feed, normal speed, low-speed material clearing)

Блокировка: Photoelectric jam signal from downstream fed into DI for automatic speed reduction; emergency stop wired to drive safety circuit

Торможение: Built-in chopper + external braking resistor for fast stopping to prevent material pile-up

Key Parameter Settings

Ускорение: 8 с; Deceleration: 6 с; stall protection enabled

Application macro: Factory default macro; use embedded sequence programming to reduce PLC I/O count

Field Benefits: High low-speed torque without belt slip; lower mechanical shock and belt wear compared with star-delta starters. This is a widely used legacy application; preferred replacement part is ACS355-03E-23A1-4.

Риск: Regular dust cleaning required for dusty environments; overvoltage alarms occur if deceleration is too fast.

Случай 2: Woodworking Machinery – Sanding Machine Feed Roller Drive

Нагрузка: Feed roller of sanding equipment; fluctuating load, stable low-speed torque without speed fluctuation to avoid sanding marks on workpieces.

Схема управления

Векторное управление; DI run command; AI speed signal from main machine controller

Multi-speed selection for different workpiece thicknesses (low speed for thick boards, high speed for thin boards)

150% / 60 s overload protection to handle board jamming

Environmental Features: Cabinet-mounted IP20 unit for dusty woodworking workshops; built-in EMC filter on E-version prevents interference with proximity switches and encoders.

Ограничение: No STO safety function. Upgrade to ACS380 for new machine retrofits.

Случай 3: Screw Lifts / Bucket Elevators in Food Production Lines

Нагрузка: 11 kW vertical material handling with potential energy load; anti-rollback on shutdown.

Схема управления

Standard built-in braking chopper with external resistor to prevent load coasting downhill

Digital terminal start/stop; 4–20 mA analog speed control; Modbus RTU communication with PLC host

Level interlock: Automatic speed reduction on low material level, auto-stop on full bin

Process Notes: Waterproof control cabinet for humid conditions; strict earthing and high motor insulation resistance required.

Примечание: The ACS350 was ABB’s flagship OEM drive for bakery, extrusion and feed processing lines.

Случай 4: Extruder Auxiliary Traction Drive (Пластмассовая промышленность)

Нагрузка: Traction roller on plastic extrusion lines; constant torque with speed proportional synchronization with main extruder.

Схема управления

Вариант 1: AI speed follow signal from main drive (proportional speed regulation)

Вариант 2: Modbus RTU bus synchronization with master drive

Vector control maintains stable tension at low speed to avoid breakage or material accumulation

Embedded sequence programming for start delay and stop sequence to simplify PLC logic

Сравнение: Main extruders typically use ACS510/ACS550 while ACS350 serves as a cost-effective auxiliary drive. Re-synchronization logic is required when retrofitting to ACS380.

Случай 5: ОВК & Water Treatment Circulation Pumps (Переменный крутящий момент, PID Closed Loop)

Нагрузка: 11 kW cooling water circulation pump or constant-pressure water supply pump.

Схема управления

Режим управления: V/F scalar control; built-in PID macro; 4–20 mA pressure transmitter feedback to AI2

Goal: Maintain constant pipe pressure with variable speed energy saving

One-duty-one-standby rotation must be implemented via external PLC; the ACS350 does NOT support built-in PFC pump cycling function (difference from ACS510)

Энергосбережение: 20%~40% power reduction under partial load compared with direct-on-line operation.

Случай 6: Small CNC Machine Tools – Spindle Cooling & Conveyor Drives

Нагрузка: Machine tool feed rollers, cooling fans and chip conveyors with 11 kW rating.

Схема управления

Keypad/terminal control with multi-speed preset linked to CNC M-codes; ФПБА-01 Profibus DP adapter for CNC system networking

EMC compliance guaranteed by integrated EMC filter on E-version

Ограничение: Only for asynchronous motors; not compatible with permanent magnet synchronous motors. No longer specified for new machine builds.

Случай 7: Roller Feeders for Sand & Building Material Auxiliary Lines

Нагрузка: Roller feeders and apron feeders with frequent start-stop and shock loading.

Схема управления

Vector control to boost starting torque; stall protection triggers alarm on material jamming

Modbus RTU remote control via central PLC; real-time current and fault code monitoring

Среда: Installed in standalone ventilated cabinets for heavy dust conditions; regularly test output cable insulation to prevent earth faults.
