1.3 Wiring check
Using options or peripheral equipment
■Regenerative option
• Check that the lead wire between terminal P+ and terminal D has been removed.
• Check that the wire of the regenerative option is connected to terminal P+ and terminal C.
• Check that twisted wires have been used for connecting the regenerative option to the servo amplifier.

■Power factor improving DC reactor
• Check that a power factor improving DC reactor is connected between P3 and P4.
Page 209 Power factor improving DC reactor
*1 Remove the wire between P3 and P4.
I/O signal wiring
• Check that I/O signals are 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 page for information on
connecting I/O signals.
Page 40 Example I/O signal connections
• Check that a voltage exceeding 24 V DC has not been applied to the pins of the CN3 connector.
• Check that the plate and DOCOM of the CN3 connector have not been shorted.
