  • Fanuc Robot Application Questions and Line Tracking

    Good morning All,

    I am working on a project that trying to save some cycle time. Currently there is lift going up and down to transfer the sled, once the sled is transferred to the down position, the robot will come in and drop the part.

    Currently I am trying to let the robot come in and drop the part on the sled while the sled is transferring by the lift from up position to down position. The lift is VFD controlled, no position feed back, we can probably calculate the speed but it is probably not very accurate. Since the robot EOAT is having the part, it is not possible to install distance sensor on the EOAT to monitor the distance between robot EOAT and the sled. I am not sure if line tracking will help in this case since it is moving vertically. Any idea is appreciated, thank you!

  • Robot Controller Powered SMC block Switched 24V Question

    Good morning all,

    I have a weird issue ongoing right now and wondering if anyone can help.

    The robot controller is R30 (tall one, forgot the exact model number), M-900ib/400L. We have an SMC bock powered/controlled by the robot controller, 2 sets 24V(unswitched, switched) going to the SMC block. On the SMC block output valve bank, we used 3 positions exhaust center valve for our suction cups.

    Since this morning, when entered the cell, the suction cup started to lose suction, I assume this 3 positions exhaust center valve will need the output on to maintain suction, if that is the case, what causes the switched 24V drops from the robot controller? one of the UOP signals or one of the safety over ethernet signals? If not what could be the problem, I already tried to replace the SMC output valve bank and valves, did not work.

    Thank you!

  • PRIO-104 Device is off line help

    Good morning all,

    I am having an issue with one of our robots with an R30IB controller, every cycle when the robot goes to the home position clears all the zoning signals then fault out before OR after the next PNS call.

    The fault is resettable, it is NOT happening every cycle. We are using ethernet IP, NO DeviceNet. When the fault happens, no other communication fault appears.

    Not sure what caused this fault exactly, IO is being called every cycle, it is a config error, and it should fault every cycle I imagine.

    Will Increasing RPI on the PLC side help?

    Thanks,

    older controllers:

    at R-30ibP controllers:

    ECHO via any modern browser -->http://robot_ip/FRH/jCGTP/ECHO.HTM

    I have r30ib not plus, it have i pendent option but not remote i pendant option

    TPIF-249 R843 Remote iPendant required.

    Cause: This operation requires R843 Remote iPendant option.

    Remedy: Load the Remote iPendant option R843

  • Fanuc Robot Space Function Question

    Quote from HawkME

    Adding on to the above post:

    1. There are multiple options for which comm protocol you just. For example, EthernetIP.

    2. Hardwired IO would be rack 1. Or the EE connector which uses RO/I.

    Thank you for the answers!

    But I am still a little confused here, yes, both robots will be talking to PLC, I can set up the space function for both robot and have DI and DO mapped into PLC.

    But what about priority level? Is this going to be a GI? If I have to define a space for each robot, how does the two spaces link to each other and know who have the higher priority?

    Thank you!

  • Fanuc Robot Space Function Question

    Good morning all,

    Having a quick question regarding the space function. Since space function has priority level and playing a role like traffic cop. My question is how does the space function information shared between robot controller?

    Example is I setup a space in RB1 controller giving a priority level 10, how do I setup RB2 to use the same space but different priority?

    Thank you!
