Hello people!
I want to build a device which allows one operator to RELEASE the brakes of the robot axes to allow fast manual movement in case of emergency.
For instance, one may unlock the A1 brake and move the robot out of intereference with the production line quickly and effortlessly.
This device is already available for fanuc robots and consists in a small panel with 6 buttons, each one releases one axis brake.
The panel is connected to the robot through the same connector of the controller (replaces the controller), but only the pins for the brakes are wired.
Today i did some electrical measurements on KUKA brakes and it turned out that they are released with a voltage applied of 27V, the current drawn by each brake is between 750 and 950 milliamps and the impedance varies a little between the 6 motors but it's between 35 and 27 Ohms, which is compatible with the current measurements.
I suppose that a simple 24V power supply may do the job to release the bakes.
Do you think it's possible?
