Rotation direction
The rotation direction of the actuator is defined as a clockwise (CW) rotation as viewed from the output
shaft when a FWD rotation command is given to an FHA-C mini series actuator from a Mitsubishi
Electric servo amplifier. The rotation direction of the Mitsubishi Electric servo amplifier can be switched
with the parameter “PA14: Rotation direction selection/Moving direction selection” setting.

Shock resistance
The shock acceleration when applying a impact in the up/down and left/right directions with the center
shaft of the actuator installed horizontally is as follows.
Shock acceleration: 294 m/s
2
Direction: top/bottom, right/left, front/back
Repeating times: three each
However, never apply a direct impact to the output shaft.
1-12
Resistance to vibration
The resistance to vibration of the actuator is as follows, and this value is the same in up/down,
left/right and front/rear directions: Vibration acceleration: 24.5 m/s
2
(frequency: 10 to 400Hz)
This specification does not have a warranty period and terms against fletting wear of mechanical parts
due to micro-vibration.
