2. SIGNALS AND WIRING
Note 1. Always connect P1 and P. (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. Connect the regenerative resistor. When using a regenerative option for the MR-J3-
B-RJ006 servo amplifier, refer to chapter
11 of the MR-J3-
B-RJ006 Servo Amplifier Instruction Manual.
The regenerative resistor is not attached to the servo amplifiers of MR-J3-11KB(4)-RZ006 to MR-J3-22KB(4)-RZ006 as those of
MR-J3-11KB(4)-PX to MR-J3-22KB(4)-PX. Therefore, when using the regenerative option for MR-J3-
B-RZ006 servo
amplifier, refer to section 11.2 (4) (d) MR-J3-11KB(4)-PX to MR-J3-22KB(4)-PX (when using the regenerative options) of the
MR-J3-
B Servo Amplifier Instruction Manual.
3. The use of optional cable is recommended for the connection between the servo amplifier and servo motor. For the selection of
the cable, refer to chapter 11 of the MR-J3-
B Servo Amplifier Instruction Manual.
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. Cooling fan power supply of the HA-LP11K2 servo motor is 1-phase. Power supply specification of the cooling fan is different
from that of the servo amplifier. Therefore, separate power supply is required.
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.
