The servo amplifier could be
damaged if the optional regeneration
unit or power factor improvement DC
reactor is incorrectly connected.
Always disconnect the
connection across P-D
when connecting the
optional regeneration
unit externally.
Always disconnect
the connection
across P1-P2 when
using the FR-BEL.

Notes:
1. When using the 1-phase 230VAC (MR-J3-70A or smaller), connect the power supply to L1 and L2. Do not connect anything to L3.
2. Do not reverse the diode’s direction. Connecting it backwards could cause the amplifier to malfunction that signals are not output, and emergency stop and other safety circuits are
inoperable.
3. Use the 24VDC±10% 300 to 900mA power supply. Note that the power capacity differs according to the number of input/output points in use. Refer to “MR-J3-MA SERVO AMPLIFIER
INSTRUCTION MANUAL” for details.
4. EMG (emergency stop) contact (normally closed contact) must be installed. If it is not installed, operation will be impossible.
5. Signals with the same name are connected inside.
6. Malfunction signal (ALM) is turned on during normal operation when no alarms have been triggered.
7. Connect the shield wire securely to the plate inside the connector (ground plate).
8. Max. 3m (9.84ft) is possible in a good noise environment.
9. Refer to “MR-J3-MA SERVO AMPLIFIER INSTRUCTION MANUAL” for details on the connection. Change the parameter No. PC22 when using the 4-wire cable (MR-EKCBL30M-H/-L to
MR-EKCBL50M-H) for the HF-KP series.
10. In the final axis, connect between TRE and RDN.
11. For the motor with an electromagnetic brake. The power supply connected to the electromagnetic brake is not related to the polarity.
12. A personal computer can also be connected with the RS-422/RS-232C conversion cable (refer to “Introductory Parts” in this catalog).
13. This is for sink wiring. Source wiring is also possible. Refer to “MR-J3-MA SERVO AMPLIFIER INSTRUCTION MANUAL” for details.
