3. SIGNALS AND WIRING

3.2.2 Signal explanations

For the I/O interfaces (symbols in I/O column in the table), refer to Section 3.4.2.

(1) Connector applications

Connector

Name

Function/Application

CN1A

Connector for bus cable from preceding axis.

Used for connection with the controller or preceding-axis

servo amplifier.

 

 

CN1B

Connector for bus cable to next axis

Used for connection with the next-axis servo amplifier or

for connection of the termination connector.

 

 

CN2

Encoder connector

Used for connection with the servo motor encoder.

 

Communication connector

Used for connection with the personal computer.

CN3

Serves as an I/O signal connector when the personal

(I/O signal connector)

 

computer is not used.
