Nice work! You managed to revive it from the robot graveyard.

Hi All,

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.

Thanks everyone.

From the error code book:

Code: 2187

Message: Communication error with TP or OP or MP

Level:4

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.

Remedy:

Check the following, reconnect the teach pendant, and restart the controller. If the error persists, contact t
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.

Hi Mate, Thanks for sharing. I'm in a similar boat but with a different robot. For sure it's a challenge but its rewarding when you make some progress or learn something new. Good luck with your project.

I was just trying to use the TP screen as a simple HMI and not have a PC connected. But yes you're right everything can be done in wincaps.

Hi, I have an old rc5 controller but with only the mini pendant not the full size pendant. If I plug in a monitor to the vga port I can see the same screen as on a full size teach pendant. And when I plug in an ps2 keyboard I can navigate most of the controller using a function key, f1, f2 etc. However I cant click on buttons that aren't mapped to a function key.

I've tried connecting a ps2 mouse to the controller but it does nothing. There is no cursor although the mouse does power up.

Is there a way to get a mouse to work? Or another way to access all the buttons? I thought about a touch screen but not sure if this would work or how to connect it.

Thanks
