3. LESYH series electric slide table / Common precautions
3.1 Design / selection
Warning
1. Do not apply a load in excess of the actuator specification.
A product should be selected based on the maximum pay load and allowable moment. If the
product is used outside of the operating limit, eccentric load applied to the guide will become
excessive and have adverse effects such as creating play at the guide, degraded accuracy and
shortened product life.
2. Do not use the product in applications where excessive external force or impact force is
applied to it.
This can lead to premature failure of the product..
3.2 Handling
Caution
1. For thrust control, make sure to set it to "torque control mode", and operate within the
"pushing speed" range of each model.
Do not hit the workpiece or the stroke end with the piston in the "position control mode", "speed
control mode" or "positioning mode". The lead screw, bearing and internal stopper may be
damaged, causing malfunction.
2. Normal/reverse torque limit value is set to 100 % as a default.
It is the maximum torque (the limit value) in the "position control mode", "speed control mode" or
"positioning mode". When the product is operated with a smaller value than the default,
acceleration when driving can decrease. Set it upon confirmation with the actual equipment used.
3. Actual speed of the product can be changed by load.
When selecting a product, check the catalog for the instructions regarding selection and
specifications.
4. Do not apply a load, impact or resistance in addition to a transferred load during return to
original position.
Otherwise, the original position can be displaced since it is based on detected motor torque.
5. The table and guide block are made of special stainless,
but there can be rust on the product in an environment exposed to water drops.
6. Do not dent, scratch or cause other damage to the body and table mounting surfaces.
It may cause a loss of parallelism in the mounting surfaces, looseness in the guide unit, an
increase in sliding resistance or other problems.
7. Do not dent, scratch or cause other damage to the surface over which the table and guide
will move.
increased sliding resistance and Play can result.
8. When attaching work piece, do not apply strong impact or over moment.
If an external force over the allowable moment is applied, it may cause looseness in the guide
unit, an increase in sliding resistance or other problems.
9. Keep the flatness of mounting surace 0.02mm or less.
Insufficient flatness of a work piece or base mounted on the body of the product can cause play at
the guide and increased sliding resistance.
Do not place work and do not transform the clamp
face by a crowded installation etc.
10. Do not move the main body with the table fixed.
