3-3-2 Installation
The FHA-C series actuator is a high precision servo mechanism and great care is required for proper installation.
Install the actuator taking care not to damage accurately machined surfaces. Do not hit the actuator with a hammer.
Note that actuators are equipped with a glass encoder, which may be damaged by impact.
• Procedure
(1) Align the axis of rotation of the actuator and the load mechanism precisely.
Note 1:
Very careful alignment is required especially when a rigid
coupling is applied. Slight differences between centerlines
will cause failure of the drive-end of the actuator.
Note 2:
If needed, carefully use a wooden hammer for coupling installation.
(2) Fasten the flange of the actuator with flat washers and high strength bolts.
Use a torque wrench when tightening the fasteners.
The recommended tightening torque is shown in the table below:

(3) Refer to the HA-655 or HA-675 driver manual for cable installation.
(4) Motor cable and encoder cable
Do not pull the cable with strong force, which may damage the connection. Install the cable with slack not to apply tension
to the actuator. Keep the minimum bending radius more than 40mm, when the cable will be bent and stretched.
Do not apply torque, load or thrust to the sleeve directly.
The sleeve is adhered to the output flange, the adhered sleeve may
become detached from the output flange by the illegal torque or load.
Do not disassemble and re-assemble the actuator.
The Harmonic Drive LLC does not guarantee the actuator that has been
reassembled by others than the authorized persons by the Harmonic Drive LLC.
