Schneider Electric ATV930D22N4 22 kW Process Drive IP21

ATV930D22N4: 22 kW Altivar Process ATV900 drive with braking unit

The ATV930D22N4 is a Schneider Electric variable speed drive listed in the datasheet as: Variable Speed Drive, Altivar Process ATV900, ATV930, 22kW, 400 to 480V, with braking unit, IP21. The ATV930 is the high-performance member of the ATV900 process family. It is built for heavy-duty industrial lines that need accurate torque, regenerative-energy handling and a choice of safety and communication options. The 22 kW normal-duty size is a mid-power, wall-mounted frame with a braking unit built in. Seven Star LLC supplies the ATV930D22N4 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: ATV930 is the product range, D22 the 22 kW rating, and N4 the 400/480 V three-phase supply. The datasheet title lists the braking unit and IP21, and the variant row lists both standard and braking-chopper versions, so quote the full reference when ordering.

Technical specifications of the ATV930D22N4

Motor, supply and output ratings of the ATV930D22N4

The rated motor power is stated as 22.0 kW normal duty; 18.5 kW heavy duty. The nominal output current is 46.3 A. Continuous output current figures: 46.3 A 4 kHz normal duty; 39.2 A 4 kHz heavy duty. The supply voltage range is 380 to 480 V. Phase information from the datasheet: 3 phase.

Overload capability: 55.6 A 60 s normal duty; 58.8 A 60 s heavy duty. Motor control profiles: Variable torque standard. Switching frequency: 2 to 16 kHz adjustable; 4 to 16 kHz with derating factor. Line short-circuit rating: 50 kA.

Control, communication and safety functions of the ATV930D22N4

Communication protocols listed: Modbus serial; EtherNet/IP; Modbus TCP. Optional modules: Slot A communication module Profibus DP V1; Slot A communication module PROFINET; Slot A communication module DeviceNet. EMC filter: Integrated; With EMC plate option. Discrete inputs: 10. Analogue inputs: 3. Relay outputs: 3. Braking: By DC injection. Typical features of the ATV900 platform are modular option slots for fieldbuses, I/O and encoder feedback, plus safety functions that can be extended by a safety module. Select the options before ordering because they are not interchangeable by software.

Normal duty versus heavy duty on the ATV930D22N4

A drive of this class has two ratings on the same frame. In normal duty it delivers 22 kW with a higher continuous current but a lower overload margin; in heavy duty the rating drops to 18.5 kW with a larger overload for a limited time. The datasheet lists both sets of numbers, and a machine with frequent starts under load should be sized on heavy duty.

The built-in braking chopper only helps if an external braking resistor is added. Resistor power must be sized from the braking energy of the application: a fan with high inertia and a quick stop produces far more regenerative energy than a pump. Do not guess; compute the duty cycle.

Installation, wiring and commissioning of the ATV930D22N4

The ATV930 is wall-mounted in IP21 form and needs the clearances and mounting rules of the installation manual. Use the EMC plate and the screened motor cable, as the datasheet lists an integrated EMC filter with a plate option. Connect the braking resistor to the dedicated terminals and fit its thermal protection into the fault chain.

Commission with the keypad or the commissioning software: nameplate data, motor auto-tuning, then the ramp, current limit and fieldbus. Store a parameter backup. In Gulf plants keep the cabinet below the datasheet temperature limit and inspect the cooling fans every maintenance cycle.

Typical applications of the ATV930D22N4 in Oman and the GCC

Typical uses are larger centrifugal pumps, compressors, extruders and conveyors in process plants, and water-treatment or desalination auxiliaries where the drive must communicate by Ethernet. Where the motor runs in a hot region, check the derating curve before quoting the frame size.
