SAFETY INSTRUCTIONS (Please read the instructions carefully before using the equipment.) To use the equipment correctly, do not attempt to install, operate, maintain, or inspect the equipment until you have read through this manual, Installation guide, and appended documents carefully. Do not use the equipment until you have a full knowledge of the equipment, safety information and instructions.
[Installation/wiring] CAUTION ● To prevent injury, transport the products correctly according to their mass. ● To prevent injury, do not touch the sharp edges of the linear servo motor with bare hands when handling the linear servo motor. ● On linear servo motors, the permanent magnet on the secondary side makes the magnetic bodies generate attraction force.
Handling of Linear Servo Motor Structure of linear servo motor Linear servo motor has the primary side which consists of the iron core and coil, and the secondary side which consists of the mounting part (yoke) and permanent magnet. (excluding coreless type LM-U2P_) Primary side Laminated core Molded resin...

The magnetic fluxes generating from the permanent magnet disperse in the air from the magnet face side (facing the primary side), and most of them do not leak to the mounting part (yoke) surface side for its structure. Because of this, a magnetic attraction force occurs on the magnet face side of the secondary side, not on the mounting part (yoke) surface side.
Notes on handling • Handling must be done by the engineers who have a full knowledge of this product. • One who uses a medical device like a pacemaker must keep away from the product and equipment. • Do not wear metals such as watch, pierced earring, necklace, etc. •...
Handling of Linear Servo Motor • MR-J5-_G_-RJ and MR-J5-_A_-RJ will be available in the future. The linear servo motor uses a strong magnet on the secondary side. Incorrect handling is extremely dangerous and may cause serious accidents. Please read this chapter and thoroughly understand the contents beforehand, and handle carefully.

• Make the moving parts as light as possible, and make the base parts heavier and sturdier. • When loading works or others on the table, make the center of gravity to be as low as possible. Additionally, position of the center of gravity should be between the two linear guides.
Stopper As shown in the following figure, arrange for the table attached to the primary side to hit the stopper. Table Stopper Contact Primary side surface LINEAR ENCODER Oil proof and dust proof measures for the linear encoder is required, more so than for the linear servo motor. Contact each linear encoder manufacturer for details.

whether they can work in such environment. • On the packing condition (cardboard) shipped from our company, although the magnet on the secondary side does not have any serious impact on the outside, do not place the magnetic parts (including the primary side, other secondary side, and tools) close to the secondary side until the linear servo motor is assembled to the machine.
Secondary side (magnet) As shown in the following diagram, for lifting the secondary side, attach eyebolts to the secondary side mounting screw hole. When lifting the secondary side, to avoid the danger due to the magnetic attraction force, make the magnet face side upward, and set the lifting points in four or more points.
Storage method • Correctly store the linear servo motor in the package. Product Shock-absorbing material Package • When storing the secondary side, put a display such as "Handle with care - Strong magnetic field" on the package or storage shelf, and also take measures in drawing attention to the surrounding. •...
INSPECTION The linear servo motor functions as motor when mounted in the equipment (built-in). The IP rating is IP00. Perform the following inspections and cleaning. Precautions • The linear servo motor is structurally unrepairable. If the linear servo motor is damaged, it must be replaced. •...
Inspections on secondary side (magnet) Attachment of water and oil Check that the primary and secondary side of the linear servo motor are not wet with water or oil. When the linear servo motor is wet, the insulation on the primary side deteriorates, and may cause a malfunction. Establish the mechanical structure in which water and oil are not attached to the linear servo motor.
REPLACEMENT OF LINEAR SERVO MOTOR IN THE ABSOLUTE POSITION DETECTION SYSTEM Replacement of primary side (coil) or secondary side (magnet) After replacing the primary side or the secondary side, carry out the magnetic pole detection again. Replacement of linear encoder After replacing the linear encoder, carry out the magnetic pole detection and homing.

CONNECTION OF SERVO AMPLIFIER AND LINEAR SERVO MOTOR Precautions • Insulate the conductive parts of the terminals. • The performance is not guaranteed if the specified servo amplifier and linear servo motor are not combined. If used with unspecified combination, the servo amplifier or linear servo motor may be damaged or may operate unexpectedly. •...
Precautions for wiring Precautions • To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier and the linear servo motor. • To prevent a malfunction, do not connect AC power supply directly to the linear servo motor. For grounding, connect the grounding lead wire from the servo motor to the protective earth (PE) terminal of the servo amplifier, and then connect the wire from the servo amplifier to the ground via the protective earth of the cabinet.
