Using options or peripheral equipment
■Regenerative option
• The lead wire between the P+ terminal and D terminal should not be connected.
• The wires of the regenerative option should be connected to the P+ terminal and C terminal.
• Twisted wires should be used for connecting the regenerative option to the servo amplifier.

I/O signal wiring

• The I/O signals should be connected correctly. If the DO forced output mode is used, the pins of the CN3 connector can be
forcibly switched on/off. This mode is used to check the wiring. In this case, switch on the control circuit power supply only.
Refer to the following for details on I/O signal connection.
Page 28 I/O signal connection example
• A voltage exceeding 24 V DC should not be applied to the pins of the CN3 connector.
• The plate and DOCOM of the CN3 connector should not be shorted.
