Need Suggestion for Control Position of AC Motor Using Inverter

  1. Jul 14, 2009 #1
    Hi, I'm new in this forum. Nice to meet you all.

    I'm currently working on a project that uses AC motor. The goal is to make a position control system for the motor. Currently I'm using the Altivar 16 Square D inverter to control the speed of the motor. It uses a logic voltage to control the directoin of the AC motor and a DC voltage as the input and gives an AC voltage with a corresponding frequency that will be feeded to the motor to achieve a certain speed.

    What becomes my concern is what sensors should I use? I'm thinking of a rotary encoder, but is it enough? And I'm also concerned about the torque, is it okay if I suddenly change the direction of the motor? How to calculate or check this?

    Thanks for the help. :smile:
