Note 1. Always connect P1 and P2. (Factory-wired.) When using the power factor improving DC reactor, refer to chapter 11 of the MR-
J3-
B Servo Amplifier Instruction Manual. Use only one of power factor improving DC reactor or power factor improving AC
reactor.
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 3.7.3 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. A cooling fan is attached to the HA-LP601 and the HA-LP701M servo motors. For power supply specification of the cooling fan,
refer to section 3.10 of the MR-J3-
B Servo Amplifier Instruction Manual.
9. Configure the circuit to shut down the main circuit power supply simultaneously with the turn off of forced stop (EM1) using the
external sequence.
10. Be sure to use a magnetic contactor (MC) with an operation delay time of 80ms or less. The operation delay time is the time
interval between current being applied to the magnetic coil until closure of contacts.
