MOTION CONTROL: Lenze-acTech recently released the Potentiometer Option for SMVector NEMA 4X Inverter models.The Potentiometer option is built right into the terminal cover, providing direct front panel access. Steve Dextraze, Inverter Product Manager at Lenze-AC Tech, calls it robust and easy to maneuver and states that the potentiometer knob takes the place of the up/down buttons on the drive keypad, giving the operator manual speed control over a 0-10V analog output.
Dextraze says the SMVector inverter drive provides 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. ” Dextraze further comments that the SMVector is designed to be truly a global product, with an input voltage ranging from 120V ac 1-phase to 600V ac, three-phase, plus the 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; the SMVector NEMA 4X also offers an integral disconnect option for quick and easy motor maintenance.
