Perhaps those drives have failed due to a problem with the switchmode power supply.

Take a look to Aid 34911 ....

 

Hope this helps…

If it doesn't recover after some power cycles, then it need to be repaired.  :smileysad:

 

Here some notes taken from another *old* thread:

 

On some early PF4 and PF40 drives there were some components that were affected by heat a bit more than expected and this problem showed up. Only certain models of PF4 and PF40 drives had this issue, and only up to a certain date. Drives manuafactured after October 2005 have the improved design.


If it is determined that your drives fall into the date and catalog number range, as determined by your distributor, then these drives will be repaired.

 

Hope this helps…

About the leds over your drive... see the User Manual for the communication module you're using, troubleshooting chapter, to get infos.

 

See this LINK to get the right manual....

 

Hope this helps…

Found the manual but no explanation for that combination of lights, have tried ringing Allen Bradley tech but all they want to do is send out and engineer and won't just let me speak to an engineer!!!

Effectively the amber leds flashing is quite strange... and not documented.

 

I think the drive has to be repaired / replaced, anyway it is important you may have the opportunity to talk with a Tech Support guy to discuss the issue before / instead of sending an engineer, as this can be unnecessary.

 

Unfortunately I cannot help you on that... my suggestion is to call your Rockwell representative to ask them interact with the support ...
