External Axis Brake

matt.r.murray

Hi,

I have a system with a robot on an external axis (axis 7, coordinated motion) that requires a brake to be applied every time the axis stops at a position, even though the robot can continue motion. The brake is to then be released for subsequent axis 7 motions. The brake is controlled through a digital output and is not required for safety. Ideally, the motor servo control will stay active for accuracy when the brake is applied.

What would be a suitable way to implement this? I have tried connecting the digital outout to the DRV1BRAKE using cross connections to the digital output, but this is only good for releasing the brake, and does not engage the brake at motion stop points. I have used both MoveJDO and a TriggIO interrupt to handle this but am looking for a more streamlined solution, as operators may forget to call the brake function during operation. 

Any thoughts?
