Replacing The Unit; Hs-Mf23** Type; Hs-Fr43/73, Hs-Sf52/53/102/103 Type - Mitsubishi MELDAS HS Series Specifications And Instruction Manual

9-3 Replacing the unit

9-3-1 HS-MF23** type

With the HS-MF2** type, the amplifier/encoder section and motor section cannot be separated. The
motor and amplifier must be replaced together.

9-3-2 HS-FR43/73, HS-SF52/53/102/103 type

With the HS-FR43/73, HS-SF52/53/102/103 types, the amplifier and encoder section can be
separated from the motor section. The procedures for replacing the amplifier and encoder section are
shown below.
(1) Removing the amplifier and encoder
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 and encoder unit
out from the back.
4) Disconnect the connector connecting
the motor and amplifier. If brakes are
provided, also disconnect the brake
connector.
(2) Installing the amplifier and encoder
unit
5) 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.)
6) The motor leads are curled when
delivered. If they are uncurled, curl
them again.
7) Connect the connector connecting
the motor and amplifier. If brakes are
provided, also connect the brake
connector.
8) Align the Oldham's coupling on the
encoder side with the hub on the
motor side.
9) Assemble
amplifier and encoder unit while
taking care to not catch the leads.
10) Fix with four hexagon socket bolts.
