1.3 Operating conditions
1.3.1 Available Conditions for Operation
When selecting a desired model of shaft-type linear servo actuator, you must ensure that the
selected actuator satisfies the following two conditions.
[Condition 1]
The thrust required for acceleration must not exceed the maximum thrust of the shaft-type linear
servo actuator.
[Condition 2]
The thrust during continuous operation must not exceed the rated thrust of the shaft-type linear
servo actuator.
The above conditions are explained by using a trapezoid operation as an example.
