Uxbridge, MA Lenze-AC Tech released higher power, enhanced SMVector NEMA1 drives. According to company officials, with its price, flexibility and power range now extended to reach 30 hp, the drive offering excels in traditional VFD applications as well as in environments where inverter technology was once considered too costly. The company says increased capabilities include an additional programmable digital input, terminals for RS-485 communications, and an enhanced keypad.
Deb Kling, Lenze-AC Tech marketing manager, says the drive carries all the features required by demanding applications, including four modes of operation — V/Hz, enhanced V/Hz, vector speed, and torque — plus high starting torque, auto-tuning, advanced low-speed control, and dynamic speed regulation. Kling describes the SMVector as designed to be truly a global product, with an input voltage ranging from 120 Vac 1-phase to 600 Vac, 3-phase. “Last but not least,” she concludes, “the drive includes our Electronic Programming Module or EPM, a removable chip that is the drive’s memory and allows a customer to program multiple drives in just seconds.”
