Providing dynamic performance for low-power motor control, the ABB ACS355-03E-01A2-4 variable frequency drive integrates advanced scalar and vector control configurations for micro-drive installations. Engineered for rapid cabinet integration and OEM machine production, this three-phase 400V class AC drive offers exceptional precision in speed regulation, making it ideal for food and beverage, material handling, and textile processing applications. Equipped with an integrated Safe Torque Off (STO) terminal, it guarantees compliant functional safety (SIL3) directly out of the box without requiring external safety contactors.
| Parameter | Specification Value |
|---|---|
| Manufacturer | ABB |
| Model / Article Number | ACS355-03E-01A2-4 |
| Product Series | ACS355 Machinery Drive |
| Frame Size | R0 |
| Enclosure Rating | IP20 / UL Open Type |
| Input Voltage | 3-phase 380 to 480 VAC (+10% / -15%) |
| Input Frequency | 48 to 63 Hz |
| Nominal Output Power | 0.37 kW (0.5 HP) |
| Nominal Output Current | 1.2 A |
| Overload Capacity | 1.5 x nominal current (1.8 A) for 1 minute every 10 minutes |
| EMC Protection | Integrated C3 Filter (for European and industrial grids) |
| Control Interfaces | 5 Digital Inputs, 2 Analog Inputs, 1 Analog Output, 1 Relay Output, 1 Transistor Output |
| Shipping Weight | 1.20 kg |
| Physical Dimensions | 169 mm (H) x 70 mm (W) x 161 mm (D) |
| Terminal Group | Designation | Functional Assignment |
|---|---|---|
| Power Terminals | U1, V1, W1 | 3-phase mains supply input (380 to 480 VAC) |
| U2, V2, W2 | Motor connection terminals | |
| BRK+, BRK- | External dynamic braking resistor terminals | |
| Control & Safety I/O | DI1 ... DI5 | Configurable digital inputs (24 VDC PNP/NPN) |
| AI1, AI2 | Analog reference inputs (0 to 10 V, 0 to 20 mA) | |
| X1D (STO) | Dual-channel Safe Torque Off connections (OUT1, OUT2, IN1, IN2) |
The ACS355-03E-01A2-4 directly replaces legacy ACS350-03E-01A2-4 models. Footprints and wiring locations are fully identical. Note that parameter migration requires an ABB FlashDrop tool (MFDT-01) or a DriveWindow Light setup, as the internal parameter indexes differ slightly in the firmware between the ACS350 and ACS355 series.
The R0 frame size depends entirely on internal convection fans and heat dissipation channels. When installing multiple drives side-by-side in a control panel, verify that the horizontal clearance is maintained at 0 mm only if the surrounding air temperature stays below 40 degC. If ambient temperatures inside the cabinet reach 40 to 50 degC, output current must be derated by 1% for every 1 degC exceeding the nominal limit.
For optimal safety performance, do not bypass the Safe Torque Off (STO) terminals. If STO is not connected to a dual-channel safety relay, the pre-installed factory jumpers must remain firmly placed across the X1D terminal block, otherwise, the drive will trigger fault code F0021 (STO active) and inhibit startup. Always run shielded motor cable and secure a 360-degree ground clamp at the drive's grounding plate to eliminate EMI feedback to weak analog loops.
