9-3-3 HS-SF202 type
With the HS-SF202 type, the amplifier section, encoder section and motor can be separated. The
procedures for replacing the amplifier section and encoder section are shown below.
(1) Removing the amplifier unit
1) Wait at least 10 minutes after turning
the power OFF, and then remove the
connector.
2) Remove the four hexagon socket bolts
installing the amplifier and encoder
unit.
3) Pull the amplifier unit out from the
back.
4) Disconnect the connector connecting
the encoder and amplifier.
5) Disconnect the connector connecting
the motor and amplifier.
(2) Removing the encoder
6) Remove the four pan-head screws, and
remove the encoder.
(3) Installing the encoder.
7) Align the Oldham's coupling on the
encoder side with the hub on the motor
side.
8) Install the encoder onto the motor, and
tighten the four screws. Set the encoder
installation angle as shown in the upper
right photograph.
(4) Installing the amplifier unit.
9) Replace the O-ring. (If the motor has
been used, the O-ring may be
expanded because of oil, etc. Thus,
always replace the O-ring when
replacing the amplifier.)
10) The motor leads are curled when
delivered. If they are uncurled, curl
them again.
11) Connect the connector between the
encoder and amplifier.
12) Connect the connector between the
motor and amplifier.
13) Assemble the motor and amplifier unit
so that the motor lead wraps half way
around the encoder periphery and the
encoder lead fits in at a position
opposite the motor lead. (Refer to lower
right photograph.) Take special care to
prevent the wires from catching.
14) Fix with the four hexagon socket bolts.
