Does anyone have any suggestions on how to fix a 2187 Communication error with TP or OP or MP error code on a RC5 controller?
I've tried the remedies suggested in the manual but with no luck. I have tried a different pendant but it didn't help, I even tried the dummy pendant and no pendant. However I don't have access to denso service.
On boot up the robot gets stuck "loading the project" and is unresponsive. I can download the error log using wincaps and find the 2187 error. Unfortunately it won't let me upload anything successfully.
I suspect I damage the mainboard as I had to replace a brake relay on it recently, however I cannot see anything obvious. Also if there are any schematics of the internals of the controller that would be greatly appreciated.
From the error code book:
Message: Communication error with TP or OP or MP
Description: A communication error has occurred between the teach pendant and the controller. Possible causes are: 1. Pendant cable broken, short-circuited, or loosely connected. 2. Teach pendant defective.

he DENSO Robot Service Section. 1. The pendant cable is correctly connected, without damage or short-circuit. 2. The teach pendant is not broken or damaged.
