Rk05 Annual Procedure

This document outlines the annual maintenance procedure for the RKO5 disk drive. The primary purpose is to perform cleaning, inspection, and verification of proper drive alignment to ensure correct operation and power supply compliance.

Key components of the procedure include:

• Prerequisites: Detailed requirements including tools (oscilloscope, multimeter, etc.), safety precautions regarding electrical shorts and powerful servo motors, and environmental cleanliness.
• Cleaning & Inspection: Procedures for replacing the absolute filter, cleaning components with Texpads, inspecting the spindle drive belt, and checking linear positioner bearings.
• Servo System Adjustments: A comprehensive technical section describing the use of the ALIGNX diagnostic program and an oscilloscope to adjust various parameters, including Sine/Cosine Amplitude and Offset, Velocity, and Limit signals.
• Postrequisites: Final administrative steps, including surrendering work authorizations and filing reports for any outstanding issues.
• Attachments: A reference table defining potentiometer functions and a guide for the RKO5 alignment program.

The document emphasizes that this procedure should be performed in conjunction with the RKO5 Quarterly Procedure (CMP-63591-016).
