ACS355 — ABB's Machinery Drive for Demanding Industrial Applications
The ACS355 is ABB's top-tier micro drive for industrial machinery. The ACS355-03U-38A0-4 covers the 25HP / 18.5kW rating in a compact R4 frame at 480V — serving the mid-range of the ACS355 family's 0.37 to 22kW output range.
Its primary application domains include material handling, food and beverage processing, and the processing of rubber, plastic, and wood. These are demanding environments requiring reliable motor control, flexible connectivity, and fast commissioning — all defining characteristics of the ACS355 series.

Motor Control — Open Loop Vector (Sensorless Vector)
The ACS355-03U-38A0-4 implements open loop vector control — ABB's sensorless vector algorithm that delivers accurate speed and torque regulation without a motor encoder.
Open loop vector control calculates the motor's flux and torque using mathematical models of the motor — adapting to the motor's actual operating conditions in real time. The result is performance significantly beyond basic V/Hz control:
  • Speed regulation: Tight speed regulation at low loads and during load transients — maintaining the set speed even as the motor load changes suddenly.
  • Low-speed torque: High torque delivery at low speeds without encoder feedback — enabling smooth starting under load and controlled low-speed operation.
  • Motor compatibility: Works with standard induction motors without additional hardware (no encoder, no tachometer).

Application Scenarios
Conveyor drive upgrade: A material handling conveyor is upgraded from a fixed-speed motor to variable speed control. The ACS355-03U-38A0-4 provides 25HP variable-frequency control with smooth acceleration and deceleration — eliminating belt slippage and mechanical shock during starts.
Food processing machine drive: A food and beverage processing machine requires hygienic-rated variable speed motor control. The ACS355-03U-38A0-4's compact R4 frame fits within the machine's control cabinet while providing the required motor control performance.

Frequently Asked Questions
Q1: What is the difference between Normal Duty (ND) and Heavy Duty (HD) ratings for the ACS355-03U-38A0-4?
The ACS355-03U-38A0-4 is rated at 25HP / 38A in the Heavy Duty configuration (150% overload for 1 minute). In Normal Duty service (110% overload), the same hardware may support a slightly higher continuous power rating. For applications with high cyclic overload demands — such as conveyors with frequent starts under load — the HD 150% rating confirms the drive's suitability.
Q2: Does the EMC filter need to be connected for CE-compliant installation?
The ACS355-03U-38A0-4 ships with its internal EMC filter disconnected. For CE marking compliance in environments requiring conducted emission limits (EN 61800-3 Category C2 or C3), the EMC filter must be connected via the internal EMC filter link. This is a simple screw connection inside the drive — refer to the ACS355 hardware manual for the specific connection point.
Q3: What fieldbus options are compatible with the ACS355-03U-38A0-4?
The ACS355 supports a wide range of fieldbus protocols through plug-in option modules. Available adapters include PROFIBUS-DP, PROFINET, EtherNet/IP, Modbus TCP, CANopen, DeviceNet, and others — all via the drive's option slot. The specific adapter code is appended to the base part number (e.g., +K454 for PROFIBUS, +K475 for Ethernet/IP+Modbus TCP+PROFINET).
Q4: What application macros are pre-loaded in the ACS355-03U-38A0-4?
The ACS355 includes multiple application macros: ABB Standard (general purpose VFD operation), Hand/Auto (local/remote control switching), PID Control (process feedback with integrated PID controller), Torque Control, and Sequential Control. These macros pre-configure the drive's parameters for the specific control mode — reducing commissioning time from hours to minutes for standard applications.
Q5: What is the maximum cable length between the drive and motor?
Cable length limits depend on the motor cable type, the drive's switching frequency setting, and whether an output reactor or du/dt filter is used. For standard shielded motor cables without additional filtering, ABB specifies maximum cable lengths in the ACS355 hardware manual — typically 100m for standard applications. Longer cables or high-frequency switching may require an output reactor to limit du/dt stress on motor insulation.
