ATV930D11N4

The Schneider Electric ATV930D11N4 is a variable speed drive belonging to the Altivar Process ATV900 series, designed for industrial process applications. It is rated for an 11 kW motor power on a 400-480 V three-phase supply.

This drive supports both asynchronous and synchronous motors and features an integrated braking unit and an EMC filter. It offers IP21 / UL Type 1 enclosure protection and is designed for wall-mount installation. Key electrical specifications include a rated supply voltage of 380-480V with a tolerance of -15% to +10%, a maximum output frequency of 599 Hz, and a continuous output current of 23.5 A at 4 kHz for normal duty applications.

Advanced features include multiple motor control profiles (variable torque, optimal torque, constant torque, permanent magnet motor, synchronous reluctance motor), 16 preset speeds, and adjustable linear acceleration/deceleration ramps. Integrated safety functions such as Safe Torque Off (STO) and Safe Stop 1 (SS1) are also included. Optional fieldbus expansion is available via Slot A, supporting protocols like Profibus DP V1, Profinet, DeviceNet, EtherCAT, and CANopen. The drive supports four-quadrant operation with DC injection braking.

Applications for the ATV930D11N4 include variable speed control of pumps, fans, and compressors in industrial settings, motor speed regulation in manufacturing automation, and safety-critical drive applications requiring certified safety functions.
