The duty ratio is the operating rate shown as the actuator's operating time during one cycle,
expressed as a percentage.

Ambient temperature and duty ratio
A push motion is a function that pushes the slider against workpiece, etc. and holds it like an air cylinder..
Make sure to confirm the method of use and precautions stated below before using it..
•The “Correlation between Push Force and Current Limit” shows lower guidelines for push force for each current limit value.
•Individual differences in the motor and variations in machine operation may cause the push force lower limit to be exceeded by around
40%, even if the current limit value is the same.
This is especially true when the current limit value is 30% or lower, and the push lower limit could be exceeded by 40% or more.
Notes
[Adjustment of the push force]
•The force of the push motion (push force) can be adjusted by changing the “Push
Force (%)” of the ELECYLINDER.
•To select the most suitable model, confirm the push force at the “Correlation
between Torque and Current Limit” of each product page.
[Method of lead selection]
Select a lead whose desired push force is within the recommended area of the
current limit value (colored area in the graph).
Taking the EC-(D)WS10 type in the right graph as an example, when the desired
push force is 100N, Lead 6 is appropriate. If Lead 3 is selected, the adjustment area is
limited.
[Precautions]
When a push motion is performed using a slider type, it is necessary to consider the
dynamic allowable moment of the guide. Limit the push current so that the reaction
moment generated by the push force does not exceed the dynamic allowable
moment (Ma and Mb) specified in the catalog.

The duty ratio is the operation rate in % of the actuator operating time in one cycle.
For ELECYLINDER types, the duty ratio is limited as shown below.
The duty ratio for operations at the maximum speed and acceleration/deceleration is as follows.
