Can I use an inverter and AC induction motor in a positioning application?
That depends on the required precision, and the slowest speed the motor will must turn and still deliver torque. The SJ100 inverter will deliver full torque while turning the motor at only 0.5 Hz (15 RPM). DO NOT use an inverter if you need the motor to stop and hold the load position without the aid of a mechanical brake (use a servo or stepper motion control system).
