8. Do not apply aload ,impact or resistance in addition to the transferred during return to
origin.
9. Do not den
’t ,scratch or cause other damage to the body and table mounting surfaces.
10. Do not hit the table with the workpiece in the positioning operation and positioning range.
11. There is a type where grease is applied to the dust seal band for sliding.When wiping off
the grease remove foreign matter,etc.,be sure to apply grease again.
12. For bottom mounting, the dust seal band may be deflected.
6.3 Mounting
Caution
1. Keep the flatness of mounting surace to within [0.1mm or less for length 500mm].
Insufficient flatness of the work piece or the surface onto which the actuator body is to be mounted
can cause play in the guide and increased sliding resistance.
2. When mounting the workpiece or other device to the actuator tighten the fixing screws with
adequate torque within the specified torque range.
Tightening the screws with a higher torque than the maximum may cause malfunction, whilst
tightening with a lower torque can cause the displacement of the mounting position or in extreme
conditions detaching of the work piece.
Use screws with adequate length, but with length less than the maximum thread depth.
The use of screws that are to long can touch the body and cause malfunction.
3. When mounting the actuator, use screws with adequate length and tighten them to the
adequate torque. And use all mounting holes to maintain the catalogue performance.
Tightening the screws with a higher torque than recommended may cause malfunction, whilst the
tightening with lower torque can cause the displacement of mounting position or in extreme
conditions the actuator could become detached from its mounting position.
4. When mounting the actuator, leave a gap of 40mm or more to allow for bending of the
actuator cable.
6.4 Precaution on maintenance
Warning
1. Turn off the power supply before maintenance and replacement of the product.
