*1 P3 and P4 are connected from the factory. If using a power factor improving DC reactor, remove the short-circuit bar between P3 and
P4, then connect the power factor improving DC reactor. Additionally, the power factor improving DC reactor and a power factor
improving AC reactor cannot be used together.

*2 Connect P+ and D terminals. P+ and D are connected from the factory. If using a regenerative option, refer to the following.
Page 269 Regenerative option
*3 Option cables are recommended for servo motor power cables and encoder cables. For selecting cables, refer to "Cables/connector
sets" in the following manual.
Rotary Servo Motor User's Manual (For MR-J5)
*4 If ALM (Malfunction) output is disabled with a servo parameter, configure a power circuit which switches off a magnetic contactor after
detection of an alarm occurrence on the controller side.
*5 For connecting servo motor power wires, refer to "CONNECTION OF SERVO AMPLIFIER AND ROTARY SERVO MOTOR" in the
following manual.

*6 Use the magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of
80 ms or less. The bus voltage may drop depending on the main circuit power supply voltage and operation pattern, causing a dynamic
brake deceleration during a forced stop deceleration. If dynamic brake deceleration is not required, delay the time to turn off the
magnetic contactor.
*7 If wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.

*8 Connecting the servo motor for an incorrect axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
*9 For 1-phase 200 V AC to 240 V AC power supply, connect the power supply to L1 and L3. Leave L2 open.
*10 If operating the on switch and off switch of the main circuit power supply with a DC power supply, do not share the 24 V DC power
supply for interface with the magnetic contactor. Use the power supply designed exclusively for the magnetic contactor. Refer to the
following for the magnetic contactors that can be used.
Page 334 Driving on/off of main circuit power supply with DC power supply (1-axis servo amplifier)
Operating the on switch and off switch with the DC power supply meets IEC/EN 60204-1 requirements. Also, change the configuration of
the part inside the dotted line as follows.
Servo motor
Malfunction overheat protection
RA1 RA2
Emergency stop switch
24 V DC
*11 When connecting a linear servo motor that has a thermal protector, add a contact that interlocks with the thermal protector output of the
linear servo motor.
*12 For MR-J5-500_ and MR-J5-700_ servo amplifiers, the CNP1 connector is divided into two: CNP1A connector (L1/L2/L3) and CNP1B
connector (N1/P3/P4).
*13 Even if the control circuit power supply is separated from the main circuit power supply using an uninterruptible power supply (UPS) or
insulation transformer, do not ground L11 and L21.
