1. Industrial Structural Design & Superior Environmental Adaptability of Schneider ATV320U22N4C

Compact Wall-Mounted Book-Style Structure

Schneider ATV320U22N4C adopts a slim vertical book-type casing tailored for standard wall-mounted cabinet installation and OEM machine integration. With compact dimensions of 140mm width, 184mm height and 158mm depth, and a net weight of 2.1kg, the unit supports neat side-by-side arrangement to maximize cabinet space utilization. The IP20 enclosure grade effectively blocks solid dust and particle intrusion, ensuring stable internal circuit operation in standard industrial workshop environments.

Wide-Range Temperature & Vibration Resistance Performance

Schneider ATV320U22N4C maintains full-power continuous operation from -10°C to +50°C without power derating, and supports conditional operational output up to 60°C with proper power adjustment. It withstands 5% to 95% non-condensing humidity and complies with industrial 3C3 and 3S2 environmental classification standards. The reinforced mechanical structure resists 1.5mm low-frequency vibration deflection and 10m/s² high-frequency vibration acceleration, capable of enduring 150m/s² instantaneous shock impact, perfectly adapting to long-term unattended operation in complex factory conditions.

2. 2.2kW Heavy-Duty Electrical Performance & Precision Motor Control of Schneider ATV320U22N4C

Standard Medium-Duty Electrical Parameters

Schneider ATV320U22N4C delivers stable 2.2kW heavy-duty motor power with 5.5A nominal output current and 5.7kVA apparent power at 500V input. Compatible with 380V to 500V three-phase industrial power grids, the drive tolerates -15% to +10% grid voltage fluctuation and supports global 50/60Hz power frequency standards. It features 8.7A maximum input current at 380V and 6.6A at 500V, with stable voltage and current output eliminating motor speed deviation during variable medium-load operation for consistent mechanical efficiency.

High-Torque Full-Speed Regulation & Intelligent Energy-Saving Logic

Schneider ATV320U22N4C provides 170% to 200% transient overtorque capacity, effectively handling instantaneous heavy startup loads and sudden load fluctuations for complex mechanical equipment. It supports ultra-wide 0.1Hz to 599Hz frequency adjustment, covering low-speed constant-torque transmission and high-speed precision operation scenarios. The adjustable switching frequency ranges from 2kHz to 16kHz (4kHz nominal switching frequency), reducing motor electromagnetic noise and mechanical resonance. Dedicated fan and pump energy-saving algorithms cut operational power consumption by up to 30% during continuous cyclic working conditions.

3. Certified Multi-Safety System & Multi-Protocol Networking of Schneider ATV320U22N4C

Full-Certified Embedded Machine Safety Functions

Schneider ATV320U22N4C integrates factory-certified multi-safety functions including Safe Torque Off (STO, SIL 3), Safe Stop 1 (SS1) and Safely Limited Speed (SLS), fully compliant with international machinery safety regulations. Built-in safety modules eliminate reliance on external safety relays, simplifying cabinet wiring and reducing system failure risks. Comprehensive electrical protection covers input phase loss, motor phase short circuit, ground fault, overload, overvoltage, undervoltage and internal overheating, providing full-range hardware protection for both drive and motor equipment.

Dual Fieldbus Communication & High-Precision I/O Configuration

Schneider ATV320U22N4C features native Modbus RTU and CANopen dual fieldbus protocols for seamless connection with industrial PLC and HMI systems, enabling real-time operational data monitoring, remote parameter tuning and fault log retrieval. Optional expansion cards support PROFINET, EtherNet/IP, Profibus and other mainstream industrial networks. Equipped with 7 multi-function discrete inputs, 3 relay outputs and 3-channel 10-bit high-precision analog terminals, it supports 0-10V voltage, ±10V differential voltage and 4-20mA current signal access, meeting complex interlock control and high-precision data acquisition demands for medium-duty automated machinery.
