Introduction

The YAMAHA YK120X and YK180 series robots are SCARA type industrial robots developed based on years of YAMAHA experience and achievements in the automation field as well as efforts to streamline our in-house manufacturing systems.

The SCARA robots have a two-joint manipulator consisting of an X-axis arm and a Y-axis arm, and are further equipped with a vertical axis (Z-axis) and a rotating axis (R-axis) at the tip of the manipulator. The YK120X and YK180 series robots can be used for a wide range of assembly applications such as installation and insertion of various parts, application of sealant, and packing operations.

This owner's manual describes the safety measures, handling, adjustment and maintenance of YK120X series robots for correct, safe and effective use. Be sure to read this manual carefully before installing the robot. Even after you have read this manual, keep it in a safe and convenient place for future reference.

This owner's manual should be used with the robot and considered an integral part of it. When the robot is moved, transferred or sold, send this manual to the new user along with the robot. Be sure to explain to the new user the need to read through this manual.

This owner's manual explains the YAMAHA industrial robots YK120X series standard models (YK120X, YK150X), clean room models (YK120XC, YK150XC), and YK180X series (YK180X, YK220X).

Some descriptions ofYK120XC andYK150XC are not listed in this manual when they are the same as standard models. Refer to the descriptions of standard models. For information on difference between the clean room model and standard model, refer to the description on the next page.

For details on specific operation and programming of the robot, refer to the separate "YAMAHA robot controller owner's manual".
