Lenze Americas: Potentiometer option
Lenze-AC Tech’s Potentiometer Option for SMVector NEMA 4X Inverter models is built right into the terminal cover, providing direct front-panel access.
Lenze-AC Tech calls it robust and easy to maneuver. 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. Suitable for use in hands-on applications where speed must be ramped up/down, such as conveyer applications or food/beverage process applications, especially if operators are wearing gloves. It uses just the right amount of control without the user having to use the keypad. The SMVector inverter drive provides 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. Designed to be a global product, with an input voltage ranging from 120VAC 1-phase to 600 VAC, 3-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 seconds. Integral disconnect option for quick and easy motor maintenance available.
