All of the products manufactured by Power Electronics® have similar programming and the event codes are also very similar across the Micro-Speed® Product Lines.
The first thing to do is check the fuses and Event Codes on your unit. If the fuses are blown, do not just replace them with new fuses. Just replacing them may make a problem worse or damage the drive. Check for wiring or other shorts first. When a problem arises, such as excessive current draw, often the unit will protect itself by shutting down, then displaying and recording an Event Code. The code reveals information about the most recent condition. See the FAQ named What is typical behavior of a PE® drive when a trip event occurs? for more information.
If the fuses are okay and the drive can power up (display is on), check for an Event Code to be displayed on the screen and check the Event Code FAQ’s below, as well as the troubleshooting steps listed in your manual. If you do not have an F-code displayed, check the “E1-E4” parameters to see the Event Codes which may have recently been displayed. To do this, press and hold the “SCROLL” button until “E” is displayed, then let go of the “SCROLL” button. “E1” will be displayed briefly, then it will display the most recent F-code recorded (newer models – Version 2.1 and higher – will also display a number in front of the F-code, indicating the number of times that particular trip has occurred). To view the previous Event Codes (in order of occurrence), tap the scroll button to read the next three recorded Event Codes at E2, E3 and E4 respectively. The presence of F-codes does not necessarily mean that the unit has been damaged.
Refer to the Event Code list below to help diagnose and troubleshoot issues with your system.
To exit from the “E” parameters, press and hold the scroll button again until “cOFF” or “rOFF” is displayed then let go. If you have an Event Code on the display, also see How can I reset my drive after an event code is displayed?
