The potentiometer option for SMVector NEMA-4X inverters is built into the terminal cover, providing direct front-panel access. The potentiometer knob takes the place of up/down buttons on the drive keypad, giving the operator manual speed control over a 0 to 10-V analog output.
The SMVector inverter drive provides four modes of operation — V/Hz, Enhanced V/Hz, vector speed, and torque — as well as high starting torque, auto-tuning, advanced low-speed control, and dynamic speed regulation. Input voltage range is from 120-Vac one-phase to 600-Vac, three-phase, plus the Electronic Programming Module, a removable chip that serves as the drive’s memory and lets customers program multiple drives in seconds.
