FAQs
Begin with confirming a 460 V supply and the drive’s 10 HP rating (approximately 22.1 A). Mount the ACS320 in a compliant enclosure, wire the motor to the drive per ABB installation guidelines, and connect the BACnet MS/TP network for BMS access. Configure basic parameters (voltage, frequency, ramp rates) and perform a thorough functional test to ensure smooth speed control, protection features, and safe lockout sequences.
Yes. The ACS320 includes built-in BACnet MS/TP support, allowing direct communication with modern building management systems. Configure device addressing, network topology, and BACnet objects to enable centralized control of pumps and fans, reducing commissioning time and enabling real-time monitoring and fault diagnostics from the BMS console.
The device is a 10 HP HVAC microdrive designed for 460 V three-phase systems and answers to 22.1 A nominal current. It is UL-listed for electrical safety and intended for OEM pump and fan applications in HVAC. The compact ACS320-03U-15A6-4 supports precise speed control and integration with standard 460 V HVAC motors.
Best suited for booster pumps, exhaust and condenser fans, and supply/return fans in commercial and industrial HVAC installations. The embedded BACnet MS/TP enables direct BMS integration, while the 10 HP at 460 V capability supports modest to mid-size motor loads. The drive’s energy-saving capabilities and compact form factor make it a strong choice for OEM equipment upgrading.
ROI benefits come from reduced energy consumption due to precise speed control, decreased commissioning time via built-in BACnet, and improved reliability from UL-listed safety features. Maintenance is simplified by a compact, service-friendly design and clear parameterization. Over the equipment lifecycle, operators can expect lower energy bills, fewer spares needs, and longer motor life due to smoother operation.
