Thank you for purchasing the single-axis robot RSH1/RSH2/RSH3. Before using this robot, read the following notes and set the origin position. The RSH1/RSH2/RSH3 single-axis robots use an incremental type or absolute type position detector. The absolute type does not require an origin search (return-to-origin) after turning the controller power back on.

Periodic inspection and maintenance are essential to ensure safe and efficient operation of MISUMI robots. This chapter describes periodic inspection items and procedures for the RSH1/RSH2/RSH3. Before beginning work, read the precautions below and also in Chapter 1 "Using the Robot Safely" and follow the instructions.
Page 46
4-1 Before beginning work When applying grease to the ball screw and linear guide, take the following precautions. WARNING PRECAUTIONS WHEN HANDLING GREASE: • INFLAMMATION MAY OCCUR IF THIS GETS IN THE EYES. BEFORE HANDLING THE GREASE, WEAR YOUR SAFETY GOGGLES TO ENSURE THE GREASE WILL NOT COME IN CONTACT WITH THE EYES.
(not dry). Apply grease if necessary. Standard robots: Albania No. 2 (Shell) Daphne Eponex No. 2 (Idemitsu) Clean room robots: LG-2 (NSK) CAUTION Failing to use MISUMI-recommended grease can shorten the life of the ball screw and the linear guide.
6 months. CAUTION Failing to use MISUMI-recommended grease can shorten the life of the ball screw and the linear guide. 4-2-4 Three-year inspection Check the following points every 3 years or more often if the robot is used frequently.
4-3 Applying grease Applying grease When applying grease to the ball screw according to periodic inspection, follow the procedure below. Grease can be applied to the guide sliding section using the grease nipples. Prepare a grease gun in this case. 1) Make sure that the power to the controller is off.
4-4 Replacing the motor Replacing the motor CAUTION A positional shift occurs by replacing the motor. It is therefore necessary to perform return-to-origin and set point data again after replacing the motor. When removing the parts, note their positional relation and assembly order. 1) Turn off the controller power.

(return-to-origin) is complete. (See the figure below.) NOTE The RSH1/RSH2/RSH3 robots use an absolute type position detector. There is no need to perform an origin search each time the robot controller is turned on and readjust the machine reference value. If for some reason the machine reference adjustment becomes necessary, please contact us.

Moment of inertia calculation CAUTION The robot must be operated with correct tolerable moment of inertia and acceleration coeffi cients according to the manipulator tip mass and moment of inertia. If this is not observed, premature end to the life of the drive units, damage to the robot parts or residual vibration during positioning may result.
