Schneider ATV320U40N4B Altivar Machine ATV320 VFD 4 kW 380-500V 3 phase Book

The Schneider Electric ATV320U40N4B is a 4 kW variable speed drive from the Altivar Machine ATV320 series, for 380-500V 3-phase supply, in book format. The ATV320 is designed for machine builder applications with built-in STO (Safe Torque Off), Modbus RTU, and CANopen communication. It provides closed-loop vector control for precise speed regulation without encoder feedback.

Technical specifications:

• Part number: ATV320U40N4B
• Manufacturer: Schneider Electric
• Series: Altivar Machine ATV320
• Power: 4 kW
• Supply voltage: 380-500V AC, 3-phase, 50/60Hz
• Format: Book

• Safety: STO (Safe Torque Off, SIL2/PLd) built-in
• Communication: Modbus RTU + CANopen built-in
• Ingress protection: IP20
• Standards: IEC/EN 61800-5-1, CE

Features and benefits:

• Wide voltage range 380-500V - covers standard 400V and 480V three-phase motor supplies
• Book format - very narrow width for side-by-side mounting of multiple drives in high-density panels
• STO built-in - SIL2/PLd safe torque off without external safety relay for IEC 62061 and ISO 13849 machine safety

Applications:

• Machine builder variable speed applications: conveyors, hoists, packaging, and material handling
• Multi-axis machine panels requiring Modbus RTU or CANopen network integration
• Machines requiring IEC 62061 or ISO 13849 safety compliance via built-in STO function
