text: <s>[INST] Powerflex 400 Summary: Motor high current/failureI have a Powerflex 400 Drive that is controlling a 30 HP motor and have had 2 motor failures in less than 1 month. There is no line reator installed and I don't know if it would help or not. The motor has a 1.15 service factor and I have used it numerous time without issues at other plants. The motor is loacted about 200 feet from the drive. It consistantly runs at a high current even with no load on the motor. FLA on the motor is 38 and though I initionally had about 20 amps of load; the load has increased overnight by 15. The conditions have not changed. Any idea as to why this motor may be failing? There are about 30 motors on this line and they have been running with no issues. I have now replaved the motor twice, the power cables once, and the VFD once. [/INST] I have a couple questions for you, what is the voltage of the drive and motor? What is the application you are performing with the drive and motor? A service factor rating in a motor is a rating similar to that of the OL rating on a drive, and the PF400 has an OL rating of 110% for one minute. Is there any output filtering between the drive and the motor? What type of cabling are you using? Is the motor VFD rated? Have a look at Chapter 5 of this guide; http://literature.rockwellautomation.com/idc/groups/literature/documents/in/drives-in001_-en-p.pdf It should help you to understand better what my questions are about. \\n </s>
