hi friends to my robot kr125 / 3 bought to learn and play,
and wanted to add an external axis of kuka.
buy the motor as its 3 axles 4,5,6 and an identical driver to its original axis to not fail ...
After analyzing the connections, buy special wiring and hoses with a screen, mount everything,
connect the motor resolver to the back of the rdw robot. to its axis marked in 7 axis.
Mount the motor wiring with its brake to a 6-pin connector to the cabinet, from the cabinet with screen hose connect its 3 wires w v u. to the driver. the brake to the brake connector, to its 2 cables free of braking.
the bridge rj45 for the data from driver 6 to driver 7. everything perfectly connected.
if I add the external axis in the software I see robot + motor .. or loose motor.
the driver is activated and attempts to turn but gives tracking error on axis 7. and does not release the brakes of the robot or 7 axis.
If I turn off the 7 axis again by software, the robot works perfectly.
(The wiring has been checked by connecting the axis 6 of the robot from the rdw to the motor 6 and it works perfectly, discarding the wiring.
I think that the drw will have a configuration for 7 axis and it is not reading axis 7.
This is my robot on my YouTube:
