Schneider Electric (Square D) ATV212HU22N4 VFD

Optimized for building fluid management, the Schneider Electric Square D ATV212HU22N4 Altivar 212 VFD is a high-performance variable speed drive engineered for 3HP 460V 3-phase asynchronous motors. As a technical SEO anchor in HVAC variable frequency drive solutions, this unit is purpose-built for centrifugal pumps, fans, and blowers, delivering substantial energy savings by matching motor speed to load demand. It features a built-in Class C2 EMC filter and supports multiple communication protocols including BACnet, Modbus, and METASYS N2, ensuring seamless integration into building management systems without additional hardware.

The ATV212HU22N4 VFD operates with a rated output current of 5.1A and is housing in an IP21 enclosure designed for vertical panel mounting. Technicians will appreciate the harmonic mitigation technology which reduces current distortion without the immediate need for line chokes. With a frequency range of 0.5 to 200 Hz and specialized V/f quadratic control profiles, this drive provides precise fluid control while protecting equipment through integrated thermal and short-circuit monitoring. For building automation systems, its compact footprint and LED status indicators simplify both initial commissioning and routine field maintenance.

• Broad Compatibility: Native support for METASYS N2, APOGEE FLN P1, and BACnet for industrial 3-phase systems.
• Energy Efficiency: Potential for up to 70% reduction in energy consumption compared to traditional motor starters.
• Harmonic Suppression: Integrated technology reduces the need for external DC chokes or line reactors in standard HVAC installs.
• Space-Saving Design: Compact IP21 frame (4.21" W x 5.63" H x 5.91" D) fits tight control panels.
• EMC Compliance: Integrated C2 filter ensures electromagnetic compatibility for commercial building environments.

Can the ATV212HU22N4 operate a 1-Phase motor?
No, this VFD is strictly designed for 3-phase asynchronous motors. Attempting single-phase operation will cause phase-loss faults.

What should I check if the drive displays 0.0Hz on start-up?
Verify the CMOd parameter for terminal control and check for 24Vdc at terminal F. Ensure the run permissive is satisfied and a speed reference is present.

Does this unit require an external display for programming?
While it includes a basic LED display, the optional VW3A1101 remote keypad is often preferred for more complex parameter tuning and fault history review.
