External Axis

  • Hello
    I am tying to connect my positioned to ABB irb 1400 m97a


    Is it possible to connect non Abb motors
    Has anybody had an experience of how to do it?
    link of the motor:

    And the last question:
    I want to find out what is the power of the motor but I don't know how to encrypt the abbreviation on the motor
    I and talking about Abb robot motors


    Thank you!

  • Is it possible to connect non Abb motors

    You can connect non ABB motor if it have suitable resolver, brake and electrical specifications.

    It is a complicated job and you must be know all motor specifications for non ABB motors.

    You can find motor spec on ABB website with part number. The part number format is "3HACXXXX-X". You can see on motor label.

  • I'm sure there's a lot more information available i the forum if you'd search :justice:
    ...but this is a pretty good thread https://www.robot-forum.com/ro…s-did-i-hook-it-up-right/



    Personally I wouldn't bother going with a 3rd party motor unless you absolutely have to, i.e. the ABB's are too big or too small for your application. Unless your time is free you're going to spend a lot more money in time, screwing around trying to get it to work, than you would buying an ABB motor. The motor you show (while I can't find much on google) looks very similar to an ABB MU10/100 motor.

  • I posted the External Axis Users Guide and the Motor Unit Product manual for 4.0 in the manuals section. There are good explanations for connecting and for a lot of the parameters. This should answer some of your questions.

  • Thank you for your replies


    I want to connect DC2T rectifier instead DC0
    And connect 2d SMB to Measurement System 2


    I have read the information about minimal configuration of external axis
    So as I understand - I should install config files for DC2T (drive system 1 ) and 2d SMB (measurement system 2)
    and fill minimal configuration


    But I have some questions
    1)
    Choose Types: Joints and specify, under parameter Logical axis, the logical number of the axis in the RAPID program. Example: Logical axis 10 will then correspond to the field eax_d in a data of the type robtarget.


    The information about logical axis is already included in Config files, so don't quite understand what I should type in this field
    2)Should I change my transformer if I connect external axis? (with the motor on the photo)


    3)Should the key disk have any information about External Axis?


    4)Are values Kp, Kv and Ti optional?


    5) If I connect motor (or configure software) non correctly will the system prevent the damage? (for example if the transformer give more load)


    Thank you

    Correct



    2)Should I change my transformer if I connect external axis? (with the motor on the photo)


    I don't remember 100% (because most of the robots we worked on had ext_axis already.
    But I don't think you need to upgrade the transformer, only the rectifier and drives.



    3)Should the key disk have any information about External Axis?


    Only if you want to be able to reboot in in silent mode, but as long as you query all then you should be OK.



    4)Are values Kp, Kv and Ti optional?


    Not really, Kv and Kp are gain factors for Velocity and Position and Integration factors, they're what you use (among other things) to tune your external axis to perform at it's best.



    5) If I connect motor (or configure software) non correctly will the system prevent the damage? (for example if the transformer give more load)


    NO! As with everything else, do it incorrectly and you might ruin something ;)
    Once set up correctly you have more safe guards for over torque and thing like that, but if you're starting blind you can easily burn up a motor....

    You may already have the larger transformer. Check the part # on the transformer against the chart in the electrical prints page that shows the transformer.
    Even if you have the smaller transformer, there should be plenty of capacity to handle the DC2T & smaller motor you intend to use.
