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.

(2) I/O signals

(a) Input signal

Signal	Symbol	Connector Pin	Function/Application	I/O Division
		No.
			Disconnect EM1-SG to bring the servo motor to a forced stop	DI-1
Forced stop	EM1	CN3	state, in which the servo is switched off and the dynamic
		20	brake is operated.
			In the forced stop state, connect EM1-SG to reset that state.

(b) Output signals
