*1 The servo amplifier is shipped from the factory with P+ and D already connected. If using a regenerative option, refer to the following.
*2 Option cables are recommended for servo motor power cables and encoder cables. For selecting cables, refer to "Cable/connector sets"
in the following manual.
Rotary Servo Motor User's Manual (HK series)
*3 This circuit is a connection example of stopping all axes when an alarm occurs. If CALM (AND malfunction) output is disabled with a
servo parameter, configure a power circuit which switches off a magnetic contactor after detection of alarm occurrence on the controller
side.
*4 For connecting servo motor power wires, refer to "CONNECTION OF SERVO AMPLIFIER AND ROTARY SERVO MOTOR" in the
following manual.
Rotary Servo Motor User's Manual (HK series)
*5 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.
*6 For 1-phase 200 V AC to 240 V AC power supply, connect the power supply to L1 and L3. Leave L2 open.
*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 This is for the MR-J5W3-_G_ servo amplifier.
*9 Connecting a servo motor of the incorrect axis to the CNP3A, CNP3B, or CNP3C connector may cause a malfunction.
*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 204 Driving on/off of main circuit power supply with DC power supply [WG]
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.
*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.
