3. MR-J2S- B4 SERVO AMPLIFIER
(d) MR-J2S-15KB4 22KB4
NFB
3-phase
380 to 480VAC
Note 1. When using the external dynamic break, refer to section 6.1.4.
2. For the power supply for the servo motor cooling fan, refer to section 2.6.2 (2).
3. When the U/V/W cable is wired to TE1 in the MR-J2S-22KB4, the crimping terminal may make contact with the PE terminal screw
depending on the orientation of the crimping terminal. Wire the cable, paying attention to the orientation of the crimping terminal.

5. Make sure to connect required number of regenerative resistors. For using the regenerative option, refer to section 6.1.1.
6. Configure the power supply circuit to shut off the magnetic contactor after detecting an alarm occurrence on the controller side.
7. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
