I have an error on a KRC4 robot: connection to power management board lost
I checked all the fuses and all the LED"s on the CCU board-Their status is normal as shown in the KRC4 manual
I still get that error, it also throws battery backup not possible PM13 and PM16 error.

On the board on right side in the controller you will see a black cable that has a USB B Connector on it ( like a printer connection ) check that connection as they come loose

Hi, thanks for the reply
I checked that connection it looks good, checked X305 looks good, checked the fuse (it is functional)
Battery is supplying 24V but those might be the suspect -
Right next is to follow the cable to the pc and try changing the usb port to another one
Power down.the controller first then swap it over -
Hi heidi
Finally how did you solve the problem about connection lost with power management ?
