2.4 CN2 wiring and signal explanation
CN2 is the connector located on the bottom right side of the front cover of the servo drive. This
connector is used for connecting the servo drive and the encoder of the servo motor. The PIN
arrangement shown from the connector in the user’s point of view is as follows. The encoder
signals may differ depending on the type of encoder.
2.4.1 Incremental encoder
◆ Connector for CN2 is optional.
- Manufacturer : 3M, CASE product name : 10320-52F0-008,
- Connector (For soldering) : 10120-3000VE
The 15 line type incremental encoder arrangement of CN2 and FMA-Series AC servo motor is
shown as the following table.
