Independent brake signal for external axis

  • We have and IRB1660ID with 2 external axis, M7 and M8. In order for this system to work as needed, we need to have one of the external axis with the brake applied while the other is running a routine with the robot. Basically, we need the brake applied to the external axis until activated, either by program or by jog operations. ABB Service has talked about an Axis Selector option (this is the first time I've heard about it), and they can't provide enough info for us to be able to validate if it would work or not. so, does anybody know anything about this option? or else, do you know if we could map an "axis activated" signal through a safety relay in order to bypass the brake voltage individually?


    Any help here would be extremely appreciated.

  • I was able to Google 3HAC040148 and view the Motor Units Gear Units (MUGU) manual. In that manual it points to a circuit diagram manual for the product MUGU. Google was not able find a viewable version from ABB. So once again perhaps Lemster can post that manual?


    It's ABB article number 3HAC039887-001. The various configurations of the axis selector option are on display.
