    I physically removed the J1 motor from the robot and left it electrically connected. When I ran it in either direction it would make a grinding sound and jerk instead of spin smoothly. So, I sent it out to be inspected/repaired and the bearings were bad. I guess the combined torque of turning the robot (X1-2) and bad bearings were enough to cause the immediate collision detect error.

    I don't think it's any of those things and here is why:

    I physically removed the motor from j1 and can turn the axis by hand and it is smooth.

    J1 and its gear reducer were full of clean grease.

    I left the brake and the encoder plugged in and turned power on. Then I held the deadman switch and pressed <Shift> and tapped <X1> to apply power to the brake.

    It was just as hard to turn the motor shaft as without power.

    Next, I put a meter on the terminals of the brake wires while it was plugged into the motor and only read 41 volts DC.

    The side of the motor has a label that reads DC90V BRAKE FOR ROBOT.

    So, I'm thinking there is a problem from the controller.

    I've been tasked with refurbishing our training station. I was basically handed a box of parts and said, "Make it work".

    After putting all the parts together I've discovered that it's a LR Mate 200iC connected to a R-30iA Mate controller. At first J1 was moving back and forth fine, but now it instantly quits and throws up a SRVO-050 Collision detect alarm. I'm wondering what would typically cause this before I start pulling the mechanical unit apart.

    This is what's really happening. They either only want trained people using their manuals, or it's a huge wall to get people to spend money on training to get a manual whenever they need it. Either way I recommend you send at least one person to FANUC training.


    I need a copy of: FANUC Robot LR Mate 200iC Mechanical Unit Maintenance Manual so that I can tear down our LR Mate 200iC Type: A05B-1139-B204 NO. 7513604 As it's turning on it's X axis about half way it clunks and trips for a collision detect.


    William, unfortunately, we are not able to send or sell a maintenance manual to users that have not gone through the mechanical disassembly class. -------------------------- Regards, Mike ----- FANUC Technical Support has Closed this TSL, if for any reason you feel a solution has not been provided please reply to this e-mail and we will continue to assist you until the problem is solved =========================================================================== FANUC is in the process of transitioning to a new ERP system that will allow us to better serve our valued customers.
