The Schneider Electric ATV31H055N4 represents an advanced variable frequency drive equipped with an integrated heat sink designed to optimize thermal performance. It operates effectively with a 3-phase supply voltage between 380 and 500 V AC, with a small tolerance of ±5%. It has a motor power capacity of 0.55 kW when operating at the nominal switching frequency of 4 kHz.
With a nominal output current of 1.9 A at this frequency, the drive employs sensorless flux vector control combined with PWM motor signaling for efficient operation. Additionally, the integrated EMC filter meets the IEC 61000-4-x standards, enabling compliance with electromagnetic compatibility regulations.
The ATV31H055N4 allows users to adjust the switching frequency within a range of 2 to 16 kHz, typically set at 4 kHz for regular applications. For enhanced performance during high-torque demands, it features a transient overload capability of 150% to 170% of the rated motor torque, which is also adjustable. Furthermore, it boasts dynamic braking capacity up to 150% torque for a duration of 60 seconds, although this feature requires an external resistor for operation.
Communication capabilities include support for protocol standards such as CANopen and Modbus RTU via RJ45 ports, enabling seamless integration into networked environments. Protection features also include phase loss monitoring, as well as overvoltage, undervoltage, thermal, and short-circuit safeguards.
The operating temperature range of the ATV31H055N4 lies between -10°C to 50°C, provided that a protective cover is fitted. The enclosure protection ratings vary, with IP20 for the upper section, IP21 for terminal areas, and optional configurations of IP31/IP41 for enhanced protection. This drive offers a versatile configuration for I/O with 3 analog inputs (ranging from 0–10 V or 0–20 mA) and 6 digital inputs, contributing to its adaptability across various applications. With a net weight of 1.8 kg, this unit is designed with a compact form factor, making it suitable for panel mounting in diverse setups.
