    Do you know if your EE port has power, because mine doesn't!

    Maybe I need to wire something in the controller to get power to the EE port?

    This is for the FANUC CRX 10iA/L Robot. The robot comes with a R30ib mini plus controller.

    No EE always has power. Did you check the proper pins in the EE?

    Check the fuse in the servoamplifier, could be burned.

    Also check the cabling RP1 between robot (EE socket) and controller (the biggest connector in the servoamplifier) - could be broken.

    What type of robot and controller do you have? Then I could tell you where to check it: pins in EE and fuse.

    In most cases in EE (24 pins type):

    0V - pin 8 and 23

    24V - pin 17, 18, 19, 20

    Check it.

    Sorry I forgot to mention, it's the new FANUC CRX cobot.

    This robot has an 8 pin connector -

    If still no power check the fuse or cables.

    Hm... the CRX has some extra options here that the CRs don't. I think you have to set some system variables to get power to that socket.

    Looks like $TLIF. There are several sub-variables that have different effects.

    $TLIF.$POWER_VOLT is defaulted to 0 (Off). You can select 1 (12V) or 2 (24V).

    Be careful -- there's also $TLIF.$VOLT_2A, which if activated will change the DO1 and DO2 into a higher-amperage power source. $TLIF.$DO_MODE can change the DOs between Unused, Sinking, Sourcing, and Push-Pull -- it would be easy to short something using the wrong mode.

    $TLIF.$POWER_MODE defaults to 1 (Digital Output Mode), but can be changed to 2 (2A supply mode, interacts with $VOLT_2A), and 3 (2-pin power supply mode).

    The fuse for the EE power is Fuse 4, but if it were blown, you should get an error message on the pendant (SRVO-228).

    Hey SkyeFire Do you happen to know where some documentation is on this? Im trying to find it in all the fanuc manuals for my crx because i believe i do not have power coming form my ee connector either. I see my $TLIF.$POWER_VOLT was 0 (changed it to 2 with no luck.

    I am trying to fix a HOST-425 Tool communication error (20) alarm. I do not see any notes on the (20) part and Fanuc support had no answer basically. I have a SCHUNK gripper that needs 1.44A which i set my tool i/f to 2A supply mode, enabled, 24v, increased timeout with no luck. Has anyone setup a CRX and EGU gripper?

    i never wanted to be an electronics therapist

    I have installed an EGU 60 on a CRX. just download the schunk plugin and it will select the correct setting for you

    Thank you but the SCHUNK wasn't the issue. I had a short across the 24v and 0v on my EE connector run which caused my fuse #11 to consistently blow every power on. I had to have a FANUC rep come and find what section of the harness was the issue. They replaced the bad run and the SCHUNK 'plugged in' smoothly.

    Found it by checking if i had power to the ee port, checked fuses, checked pinout (or quicker by isolating it to just the robot by disconnecting the robot from the controller). Unplugged the robot and turned on the controller and the fuse didnt blow indicating the short was isolated to the robot.
