POWERFLEX 700S doesn't move the motor
Fernando Teniente posted a topic in Allen Bradley / Rockwell Automation
Well, i'm working with a powerflex700S and it has a long time with us, we solve the faults that it had in that moment, but nowadays when we start the drive it shows RPM at the display, but the voltage output stays at 0. We tried with and without load and still the same problem, the display doesn't shows any alarm or fault, it just doesn't move the motor. We're trying to replicate the same conditions at the factory, but it just doesn't work. I suppose the motor is to small for the drive cause it works originally with an 800hp motor and we are working with an 50hp motor, but the employer wants to see the drive working before make any test at factory, Any idea you can give me to solve this problem... Thanks in advance
