I am wondering what considerations need to be taken into account when installing a severe duty motor. Do the conductors need to be larger, does the softstart need to be a certain percentage larger?
I am working for a client who is running a 150HP GE motor, and running it under severe conditions. He is powering it with 480V through an Altistart 48C21Yu. The softstart will power up the drive, and run for a given amount of time, than the softstart suddenly kicks off, and returns to rdy state, and does not provide an error code. Does anyone have experience with this problem? We are pretty sure it is a control voltage problem, because it kicks out and returns to the ready state, which is exactly what happens when you cut the control power, and turn it back on. Thanks!
