. (Factory-wired.) When using the power factor improving DC reactor, refer to chapter 11 of the MR-
J3- B Servo Amplifier Instruction Manual.
2. When using the regenerative option, refer to chapter 11 of the MR-J3- B Servo Amplifier Instruction Manual.
3. For the encoder cable, use of the option cable is recommended. Refer to chapter 11 of the MR-J3- B Servo Amplifier
Instruction Manual for selection of the cable.
4. If deactivating output of trouble (ALM) with parameter change, configure up the power supply circuit which switches off the
magnetic contactor after detection of alarm occurrence on the controller side.
5. For the sink I/O interface. For the source I/O interface, refer to section 3.7 of the MR-J3- B Servo Amplifier Instruction Manual.
6. For connection of the servo amplifier and linear encoder, a cable compatible with the linear encoder of a manufacturer to be
used is required. For selection of the cable, refer to chapter 3.
7. For details of connection of the servo amplifier and servo motor, refer to section 3.10 of the MR-J3- B Servo Amplifier
Instruction Manual.
8. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
9. A cooling fan is attached to the HA-LP6014 and the HA-LP701M4 servo motors. For power supply specification of the cooling
fan, refer to section 3.10 of the MR-J3- B Servo Amplifier Instruction Manual.
