10. Maximum Speed
The maximum speed of the actuator is limited to prevent resonance of the ball screw shaft and also in
consideration of the restrictions on motor speed.
Observe the maximum speed limits specified below.

Caution:
If the maximum speed limit is exceeded, noise may increase or vibration may occur
due to resonance of the ball screw shaft, in which case the service life of the actuator
may be significantly reduced.
If multiple actuators are used together, with each actuator operating independently,
create programs where each actuator does not exceed the applicable maximum
speed (see the table above). If operations of multiple actuators are synchronized,
programs should be based on the lowest maximum speed among the combined
actuators.
Create appropriate program by checking the maximum speed of each actuator.
