What makes the ATV930D22N4 a dependable choice for oil and gas duty?
Downtime on a pump or compressor skid often traces back to a drive that cannot handle the real load profile. The Schneider Electric ATV930D22N4 is a three-phase variable speed drive rated 22 kW (30 HP) in normal duty and 18.5 kW (25 HP) in heavy duty, operating from a 380...480 V supply. It is part of the Altivar Process ATV930 series and includes a built-in dynamic brake transistor.
Schneider Electric unit is built for demanding environments where continuous uptime matters. Its dual ND/HD rating lets one frame serve two load profiles, so engineers can standardize spares across a site.
Key specifications and ratings
- Supply voltage: 380...480 V three-phase (-15%/+10%), 50/60 Hz.
- Normal duty power: 22 kW (30 HP), 120% overload for 60 s.
- Heavy duty power: 18.5 kW (25 HP), 150% overload for 60 s.
- Output frequency: 0.1...599 Hz.
- Operating temperature: -15 to +50 °C standard, derating up to 60 °C.
- Protection rating: IP21/UL Type 1.
- Dimensions: 545.9 x 211 x 235 mm (H×W×D).
- Weight: 14.300 kg (31.526 lb).
The operating temperature window of -15 to +50 °C covers most outdoor skid enclosures without extra cooling. Above 50 °C, output derating applies up to 60 °C per the catalog.
How does the drive handle motor control and braking?
Motor control supports asynchronous motors in open-loop sensorless flux vector and closed-loop with encoder. Synchronous PM and synchronous reluctance motors are also supported in open and closed-loop vector control. A built-in dynamic brake transistor handles regenerative energy, but an external braking resistor is required, with a minimum value of 15 Ω.
Integrated STO safety (SIL3 / Cat. PL e) supports safe torque off without main contactor cycling. This reduces wear on contactors and supports faster restart sequences in mission-critical processes.
I/O and communication for plant integration
Integrated I/O includes 3 analog inputs, 8 digital inputs at 24 V DC, 2 analog outputs, 3 relay outputs, and 1 assignable pulse train output. Up to 3 additional I/O modules can be added for larger signal counts.
Built-in Ethernet dual-port switch and Modbus serial port provide EtherNet/IP and Modbus TCP connectivity. One option slot accepts fieldbus modules such as PROFINET, PROFIBUS DP V1, CANopen, DeviceNet, EtherCAT, or POWERLINK. Achilles Level 2 certification supports cybersecurity requirements in networked plants.
Integration note: Wiring into a fieldbus network may require an external gateway or connection module. Confirm cable and gateway compatibility with the supplier before commissioning.
Installation and environmental considerations
Mount the drive with 100 mm clearance above and below and 10 mm in front for adequate airflow. Required minimum air flow is 215 m3/h. Power terminal tightening torque is 2.5 N·m for frame sizes 1-3. The environmental class is IEC 60721-3-3 3C3 / 3S3 / 3M3, and the drive carries UL 508C, UL61800-5-1, EN/IEC 61800-3, and SEMI F47-0706 certifications.
Altitude derating applies above 1000 m: derate nominal current by 1% per additional 100 m up to 3000 m. Relative humidity tolerance is 5 to 95% non-condensing.
Why specify This unit for harsh environments?
Oil and gas operations demand rugged, field-proven equipment. This unit combines a wide operating temperature range, dual power rating, and integrated safety in one frame. Its IP21/UL Type 1 protection suits wall-mounting in controlled enclosures. For reliable sourcing of mission-critical spares, PetroPartsOnline offers application-specific selection guidance to match the drive to your load profile.
