According to the company, these high-performance VFDs support four control modes, including V/Hz, slip compensation, sensorless vector, and torque control, and come in a variety of voltage and horsepower ratings.
The ACN/ACNND series drives can control 230VAC three-phase motors up to 20 hp when powered with 230VAC three-phase, and up to 10 hp when powered with 230VAC single-phase. The 460VAC models support motor sizes up to 30 hp when powered with 460VAC three-phase, and up to 15 hp when powered by 460VAC single-phase.
All models include ample built-in I/O and support Modbus RTU. Additional I/O is supported with option cards as well as Ethernet communications that allow the drive to be controlled and monitored over Modbus TCP or EtherNet/IP.
VFD Suite, a free, user-friendly software package, allows for configuration of the ACN/ACNND drive, programming of the sequence controller, and other advanced features, such as trending.
These IronHorse ACN and ACNND drives have an 18-month warranty.
