11. Notes on Operation
11.1 Loads Received by the Actuator
11.1.1 Loads applied to RA2AC, RA2AR, RA2BC and RA2BR actuators
Align the shaft center of the rod with the moving direction of the load.
Application of a lateral load may cause actuator damage or malfunction.
If the rod receives a lateral load, provide a guide, etc., in the moving direction of the load.
Do not apply a rotational torque to the rod. If the rod receives a rotational torque, actuator damage or
malfunction may occur.
(Caution)
When installing the load, clamp the width across flats to prevent the rod from turning.
11.1.2 External force in thrust directions
Do not apply an excessive external force to the rod.
With low-lead types, the rod will not move even when an external force is applied.
If an excessive external force is applied, the nut may be damaged.
To move the rod, use the jog function or turn the slit on the shaft end using a screwdriver, etc.
Be careful not to apply in thrust directions any external force or impact load exceeding the allowable
value. If an external force or impact load exceeding the allowable value is applied, the internal parts
may be damaged.
