Connect it to the grounding terminal of the servo motor and to the protective earth (PE) of the
cabinet for grounding.
3.3.2 Power-on sequence
POINT
The output signal, etc. may be unstable at power-on.
(1) Power-on procedure
1) Always wire the power supply as shown in above section 3.1 using the magnetic contactor with
the main circuit power supply (L1/L2/L3). Configure up an external sequence to switch off the
magnetic contactor as soon as an alarm occurs.
2) Switch on the control circuit power supply (L11/L21) simultaneously with the main circuit power
supply or before switching on the main circuit power supply. If the control circuit power supply is
turned on with the main circuit power supply off, and then the servo-on command is transmitted,
[AL. E9 Main circuit off warning] will occur. Turning on the main circuit power supply stops the
warning and starts the normal operation.
3) The servo amplifier receives the servo-on command within 3 s to 4 s after the main circuit power
supply is switched on.

3.3.3 Wiring CNP1, CNP2, and CNP3
POINT
For the wire sizes used for wiring, refer to section 11.9.
When wiring, remove the power connectors from the servo amplifier.
Insert only one wire or ferrule to each wire insertion hole.
MR-J4-500B(-RJ) or more and MR-J4-500B4(-RJ) or more do not have these
connectors.
Use the servo amplifier power connector for wiring CNP1, CNP2, and CNP3.
