Unlocking Kuka motors

[federgarrido]

Hi all,
Does anyone know if it's possible lo 'unlock' the Kuka motors so we can move the robot arm without power?
Thanks in advance!

That is a question for the KUKA manual, which says:

The following options are available for moving the manipulator without drive energy after an accident or malfunction:
> Release device (optional)
The release device can be used for the main axis drive motors and, depending
on the robot variant, also for the wrist axis drive motors.
> Brake release device (option)
The brake release device is designed for robot variants whose motors are
not freely accessible.
> Moving the wrist axes directly by hand
There is no release device available for the wrist axes of variants in the low
payload category. This is not necessary because the wrist axes can be
moved directly by hand.
