For installation in the horizontal direction, it is recommended to set the
connector section downward.
HA-LH
HA-LFS (Flange type)
May be installed in any
direction.
HA-LF
HA-LFS (Flange
leg type)
Horizontal direction with
the legs downward.
Use either the legs or flange for installation.
When the servo motor with electromagnetic brake is installed with the shaft end at top, the brake plate
may generate sliding sound but it is not a fault. Refer to section 5.3 for the installation orientation of the
servo motor with reduction gear.
2.3 Load remove precautions
POINT
During assembling, the shaft end must not be hammered. Doing so can
cause the encoder to fail.
(1) When mounting a pulley to the servo motor shaft provided with a keyway, use the screw hole in the
shaft end. To fit the pulley, first insert a double-end stud into the screw hole of the shaft, put a washer
against the end face of the coupling, and insert and tighten a nut to force the pulley in.

(2) For the servo motor shaft with a keyway, use the screw hole in the shaft end. For the shaft without a
keyway, use a friction coupling or the like.
(3) When removing the pulley, use a pulley remover to protect the shaft from impact.
(4) To ensure safety, fit a protective cover or the like on the rotary area, such as the pulley, mounted to
the shaft.
(5) When a threaded shaft end part is needed to mount a pulley on the shaft, please contact us.
(6) The orientation of the encoder on the servo motor cannot be changed.
(7) For installation of the servo motor, use spring washers, etc. and fully tighten the bolts so that they do
not become loose due to vibration.
(8) For the HC-AQ series, use spring washers and apply Screw Lock to mount the servo motor. In
addition, use Helisert screws when the flange for mouthing the servo motor is made of aluminum.
