3) When you use a brake unit and a power regenerative converter for 7 kW
The lead wire of built-in regenerative resistor connected to P+ terminal and C terminal should
not be connected.
Brake unit, power regenerative converter or power regenerative common converter should be
connected to P+ terminal and N- terminal. (Refer to section 11.3 to 11.5.)
4) The power factor improving DC reactor should be connected between P3 and P4. (Refer to
section 11.11.)

Note. Always disconnect between P3 and P4 terminals.
(2) I/O signal wiring
(a) The I/O signals should be connected correctly.
Use DO forced output to forcibly turn on/off the pins of the CN1 connector. This function can be used
to perform a wiring check. In this case, switch on the control circuit power supply only.
Refer to section 3.2 for details of I/O signal connection.
(b) 24 V DC or higher voltage is not applied to the pins of the CN1 connector.
(c) SD and DOCOM of the CN1 connector is not shorted.

4.1.3 Surrounding environment
(1) Cable routing
(a) The wiring cables should not be stressed.
(b) The encoder cable should not be used in excess of its bending life. (Refer to section 10.4.)
(c) The connector of the servo motor should not be stressed.
(2) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
