Intended Use

Designed for general-purpose machine-level variable-speed control applications. PowerFlex 70 drives run conveyors, pumps, fans, mixers and machine axes up to 50 Hp with sensorless vector control, optional encoder feedback and DPI communication adapters, in panels on packaging, material-handling and process equipment. Conformal coating suits corrosive or high-humidity atmospheres (ANSI/ISA 71.04 G3), such as pulp and paper, wastewater, chemical and coastal sites. Safe Torque Off lets the drive sit in the machine's safety circuit without an external contactor.
