Start-up procedure for Fanuc Alpha servo amplifiers.

Start-Up Procedure for Fanuc Servo Amplifier (Alpha Series) – Overview

Here is a quick guide overview to start your Fanuc Alpha servo amplifier after it has been replaced, removed, or repaired in your machine.  This is an excerpt from the official Fanuc maintenance manual.  For all Alpha Series Control Motor Amplifiers (servo amplifier units  A06B-6089-H*** and  A06B-6090-H***).

(NOTE: When maintaining or inspecting the servo amplifiers, keep the power supply switched off. Also, make sure that the “CHARGING” LED (red) beside the circuit breaker on the front panel of the servo amplifier is off as well.)

Do Your Servo Motors Look Like This: A Case for Standard Reconditioning

How Standard Reconditioning can vastly decrease the odds of a catastrophic breakdown

The machine environment can be a caustic one, with all kinds of opportunity for contamination to spew onto a servo motor.  Though your system and servo’s may be running fine, it’s only a matter of time before a buildup of contaminates (such as cutting fluids and metal shavings) will eventually creep inside the bearings and the stator and make a motor vulnerable to a catastrophic breakdown.  Contamination in the encoder and brake assembly due to improper maintenance is also common.
