2.2 Linear Servomotor Installation

2-25

Installation

4. After mounting the movable table provided by the customer on the linear

guide, transfer the movable table onto the moving coil and secure them

with bolts.

• Carefully lay wiring so that no cables are caught, and fix them to the movable

table.

• For the recommended tightening torque of the bolts for fixing the moving coil,

refer to Table 2.2 Moving Coil and Recommended Tightening Torque.

Note: Use hexagon socket head cap screws made of austenite stainless steel

(equivalent to the strength class A2-70.)

5. Remove the part made of resin between the moving coil and the

magnetic way. Be careful not to get your fingers or other objects caught

between the moving coil and the magnetic way because a strong

magnetic attraction is generated between them.

6. Perform several full strokes with the movable table, and make sure that

the table may not come into contact with the magnetic way. (The size of

the gaps is not specified.)
