7. Electric actuators / Common precautions
7.1 Design and selection
Warning
1. 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, eccentric load applied to the guide will
become excessive and have adverse effects such as creating play at the guide, reduced accuracy
and reduced 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. If using in a stopper application, please select the LEYG series "slide bearing".
When used as a stopper, select the LEYG series ‘‘Sliding bearign’’ for a stroke of 30mm or
less.
4. If using in a stopper application, fix the body with the guide attachment.
("Upper mounting " or "Lower mounting")
/ See 7.3 Mounting [LEYG series] on p.45
If the body is fixed at the end of the actuator (end mounting), excessive load will act on the
actuator body, which may adversely affect the operation and life of the product.
7.2 Handling
Caution
1. INP output signal
1) Positioning operation
When the product comes within the set range by
step data
[In positon]
, output signal will be turned
on. Initial value: Set to [0.50] or higher.
2) Pushing operation
When the pushing force exceeds the [TriggerLV] value the INP ( In position) output signal is turned
on.
Please set the [Pushing force] and the [TriggerLV] within the specified range.
a. To ensure that the actuator pushes the workpiece by the inputted [pushing force], it is
recommended that the [TriggerLV] is set to the same value as the [pushing force].
b. When the [TriggerLV] and [pushing force] are set to be less than the lower limit of the specified
range, there is the possibility that the INP output signal will be switched on from the pushing
operation start position.
[Pushing force] and the [Trigger LV] within the limitation range
