3.5.2 Wiring and signal of absolute value encoder
CN2 is a connecter located in the right center of the
front part of the drive system. This is used to
connect the drive system and servo motor encoder.
The right figure shows pin array viewed from the
user connector. Encoder signal varies slightly
according to the types of encoder.
(Note ) CN2 connector is an option item.
(Based on the soldered side of the user connector)
∗ Maker: 3M
∗ Case product name: 10320-52FO-008
∗ Connector (For soldering): 10120-3000VE
Wiring between CN2 and the FMA-series AC servo motor absolute value encoder is shown on the
following table.
