ATV930D90N4C: Rugged 90 kW Drive for Oil & Gas Applications

The ATV930D90N4C is a three-phase variable speed drive from Schneider Electric's Altivar Process ATV930 series, delivering 90 kW (125 HP) in normal duty and 75 kW (100 HP) in heavy duty. It operates on a 380...480 V supply and is a wall-mounting IP21/UL Type 1 unit without a built-in braking unit.

Engineered for demanding environments, this drive combines robust construction with advanced motor control. Its dual ND/HD rating provides flexibility for varying load profiles, making it suitable for mission-critical operations in oil and gas processing.

Key Features and Technical Specifications

• Supply voltage: 380...480 V three-phase (-15%/+10%), 50/60 Hz
• Motor power (ND): 90 kW (125 HP), 120% overload for 60 s
• Motor power (HD): 75 kW (100 HP), 150% overload for 60 s
• Output frequency: 0.1...599 Hz
• Integrated safety: STO function, SIL3 / Cat. PL e per IEC 61508 and ISO 13849-1
• Operating temperature: -15 to +50 °C standard, derating up to 60 °C
• Enclosure: IP21/UL Type 1 wall-mounting
• Communication: EtherNet/IP, Modbus TCP, Modbus RTU; optional fieldbus modules
• I/O: 3 analog inputs, 8 digital inputs, 2 analog outputs, 3 relay outputs
• EMC filter: Category C3 integrated

The drive's dual-port Ethernet switch simplifies network integration, while the STO safety function ensures safe torque off for maintenance. The integrated Category C3 EMC filter reduces installation complexity and ensures compliance with EN/IEC 61800-3.

Reliability in Harsh Oil & Gas Environments

This unit is built for demanding environments, with an environmental class of 3C3/3S3/3M3 (except frame size 7) per IEC 60721-3-3. This rating confirms resistance to humidity, vibration, and temperature variations common in oil and gas plants.

For maintenance engineers, the drive's design supports ease of service. The IP21 enclosure protects against dust and dripping water, while the operating temperature range of -15 to +50 °C (with derating up to 60 °C) accommodates diverse site conditions. Additionally, the drive's power dissipation is 2104 W in ND and 1549 W in HD, requiring a minimum air flow of 295 m3/h to maintain optimal cooling.

Regular inspection of cooling fans and heatsinks is recommended to prevent overheating. The drive's altitude derating (1% per 100 m above 1000 m) should be considered for high-altitude installations.

Installation and Setup

Wall-mounting This unit requires careful attention to clearance: 100 mm above and below, and 10 mm in front. Terminal tightening torque for frame 5 power terminals is 25 N·m. The drive's dimensions (922 x 290 x 325.5 mm) and weight (58.5 kg) necessitate proper lifting equipment.

For electrical connections, ensure the supply voltage matches the drive's rating (380...480 V). The integrated EMC filter simplifies compliance with category C3 requirements. When integrating into industrial networks, note that fieldbus modules may require additional configuration or gateways; consult PetroPartsOnline for application-specific guidance.

Integration with Control Systems

The drive includes built-in EtherNet/IP and Modbus TCP ports, plus a Modbus serial port. An option slot accepts fieldbus modules for PROFINET, PROFIBUS DP V1, CANopen, DeviceNet, EtherCAT, and POWERLINK. This flexibility allows seamless integration into existing control architectures.

For safety functions, the two STO inputs enable connection to safety relays or controllers. The drive's Achilles Level 2 certification ensures cybersecurity resilience for networked operations.

Frequently Asked Questions

What is the operating temperature range of This unit?

The drive operates from -15 to +50 °C without derating. Above 50 °C, derating is required up to 60 °C. Storage temperature ranges from -40 to +70 °C.
