2 HP, Serial V7

The V7 was a low cost, high performance compact drive, operable in V/f or Open Loop Vector mode. In addition to good speed regulation, open loop vector control also provided higher torque at lower speeds. The V7 was ideally suited for applications such as conveyors, grinders, centrifuges, pumps, fans,blowers, machine tools, packaging, food processing, and commercial laundry.
