4 Installation
4.1 Design and selection
Warning
• Do not apply a load in excess of the actuator specification.
A product should be selected based on the maximum work load and
allowable moment.
If the product is used outside of the operating specification, the eccentric
load applied to the guide will become excessive and have adverse
effects such as creating play in the guide, reduced accuracy and
reduced product life.
• Do not exceed the speed limit of the actuator specification.
Select a suitable actuator by the relationship of allowable work load
and speed.
Noise or reduction of accuracy may occur if the actuator is operated in
excess of its specification and could lead to reduced accuracy and
LEFB 32 reduced product life.
• Do not use the product in applications where excessive external
14
force or impact force is applied to it.
48 - 1500
This can lead to premature failure of the product.
48
Caution
• Do not operate by fixing the table and moving the actuator body.
An excessive load will be applied to the table, which could lead to
damage to the actuator and reduced accuracy and reduced product life.
• Belt drive actuator cannot be used for vertically mounted
□ 56.4
applications.
• • • • In the case of the belt driven actuator, vibration may occur during
operation at speeds within the actuator specification, this could be
caused by the operating conditions. Change the speed setting to a
52
speed that does not cause vibration.

4.2 Mounting
(900) 1000
• Keep the flatness of mounting surface to within 0.1 mm or less.
1.97 2.10
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.
(900) 1000 (1200) (1500) (1800) (2000)
• When mounting the workpiece or other device to the actuator
3.77 4.00 4.46 5.15 5.84 6.30
tighten the fixing screws with adequate torque within the specified
0.19
torque range.
Tightening the screws with a higher torque than the maximum may
(900) 1000 (1200) (1500) (1800) (2000)
6.16 6.5 7.18 8.2 9.22 9.9 cause malfunction, whilst tightening with a lower torque can cause the
displacement of the mounting position or in extreme conditions
0.35
detaching of the work piece.

LEF*16 M4 x 0.7
LEF*25 M5 x 0.8
LEF*32 M6 x 1
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.
• When mounting the actuator, use screws with adequate length and
tighten them with adequate torque and use all of the 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.

• When mounting the actuator, leave a gap of 40 mm or more to allow
for bending of the actuator cable.
