ATV930D18N4 — Schneider Electric Altivar 930 High Performance Process Drive
The Schneider Electric Altivar 930 is Schneider Electric's flagship high-performance process drive, covering 0.75 kW to 800 kW on 380–480 V three-phase supply, combining the process industry reliability of the Altivar 680 platform with an enhanced motion control capability targeting demanding torque and speed regulation applications across oil and gas, petrochemical, metals, and power generation industries. The ATV930 delivers sub-1 ms torque response in closed-loop flux vector mode, speed regulation of ±0.001% with high-resolution encoder feedback, and a multi-motor drive capability that allows a single ATV930 to sequentially or simultaneously control two different motor configurations without hardware changes — a unique capability for redundant pump applications and standby motor installations.
The ATV930 integrates Schneider Electric's most comprehensive process control function library: cascaded PID with decouplers, model predictive control (MPC) for temperature and pressure loops, advanced motor diagnostics including bearing frequency analysis via drive current signature analysis, and a built-in oscilloscope with 32-channel recording. The drive's active front end as standard on frames above 37 kW achieves less than 3% THDi at full load without external filtering, satisfying ARAMCO and SABIC engineering standards across the full power range without additional harmonic mitigation measures. All major DCS fieldbus protocols — PROFIBUS DP, PROFINET, EtherNet/IP, Foundation Fieldbus H1 — are supported via plug-in cards.
In Saudi Arabia, the Altivar 930 KSA represents the top specification for process-critical VFD applications at major industrial complexes. ARAMCO's gas compression and liquid transfer facilities specify the ATV930 for compressor antisurge and gas turbine auxiliary drives where sub-millisecond torque response prevents process trips. SABIC's advanced polymer and specialty chemical plants use the ATV930 for extruder and reactor agitator drives where model predictive control improves product uniformity. The SEC power generation fleet uses ATV930 for boiler feedwater pump and turbine auxiliary drives.
Razz Middle East supports ATV930 projects from specification to commissioning, providing ARAMCO DEP compliance documentation, Foundation Fieldbus integration support, MPC configuration, and 24/7 technical helpdesk coverage for process-critical ATV930 installations across Saudi Arabia.

Key Features & Benefits
- Sub-1 ms torque response in closed-loop flux vector mode enables compressor antisurge control and turbine auxiliary drive applications where standard drives with 5–10 ms response cause process trips.
- Active front end standard on frames above 37 kW achieves less than 3% THDi at full load, meeting ARAMCO DEP and SABIC engineering harmonic limits across the full power range without additional filters.
- Model predictive control (MPC) algorithm for temperature and pressure loops reduces process variability by anticipating load changes before they affect the controlled variable, improving product quality in polymer and chemical processes.
- Current signature analysis diagnostic function detects bearing defect frequencies in the motor's drive current without vibration sensors, providing advance warning of bearing failure in inaccessible motor installations.
- Multi-motor capability allows a single ATV930 to sequentially or simultaneously control two different motor configurations, enabling redundant standby motor switching without a second drive unit.
- Foundation Fieldbus H1 communication card option integrates the ATV930 into ARAMCO and SABIC DCS installations using FF H1 as the field device protocol, eliminating the need for protocol converters.
- 32-channel oscilloscope with time-stamped recording captures transient process events and drive responses simultaneously, providing definitive root-cause evidence for process trips and quality incidents.
Industrial Applications in Saudi Arabia
- Gas compression train antisurge control drives at ARAMCO's Haradh, Hawiyah, and Khursaniyah gas processing plants, where sub-millisecond torque response prevents compressor surge during gas load transients.
- Advanced polymer extruder main and melt pump drives at SABIC specialty chemicals facilities in Jubail, where model predictive control reduces melt temperature variability and improves product molecular weight distribution.
- Boiler feedwater pump drives at SEC power generation stations, where active front end harmonic performance satisfies the utility's own IEEE 519 requirements without additional harmonic mitigation equipment.
- Turbine generator lube oil and cooling water pump drives at independent power producer (IPP) facilities in Saudi Arabia, where redundant drive capability maintains cooling system availability during scheduled maintenance.
- Refinery crude charge pump and vacuum distillation overhead condenser pump drives at ARAMCO refineries, where current signature diagnostics provide predictive bearing maintenance data to the asset management system.
- Aluminium cell bus duct and pot room crane hoist drives at Ma'aden Aluminium in Ras Al Khair, where closed-loop torque control maintains precise current loading on reduction cells during anode change operations.
- High-pressure water injection pump drives at ARAMCO offshore platforms and onshore water injection facilities, where the drive's process control capability eliminates separate PID controller hardware.
