What must be done before replacing a failed motor in a FANUC robot?

Before replacing a failed motor in a FANUC robot, removing all the hardware from the old motor shaft is essential. This step is crucial because the components that are connected to the motor, such as gears, couplings, or other attachments, must be detached to facilitate the proper installation of the new motor. If these components are not removed, it can hinder the replacement process, lead to misalignment, and prevent the new motor from operating correctly.

Moreover, ensuring that the old motor's shaft is clean and free of any attachments guarantees that the new motor can be fitted seamlessly, promoting efficient operation and reducing the likelihood of future problems. While running diagnostics checks and calibrating the new motor are also important steps, they are performed after the physical replacement of the motor to ensure that everything is functioning as intended. Much of the preparatory work lies in successfully detaching the old motor's hardware.
