Notes:
1. The above connection diagram applies only to the MR-J2S-A type.
Refer to “MR-J2S-MB SERVO AMPLIFIER INSTRUCTION MANUAL” for
details on the MR-J2S-B type.
2. When using the dynamic brake, change parameter No.1 (for MR-J2S-A type).
Refer to “MR-J2S-MA SERVO AMPLIFIER INSTRUCTION MANUAL” for
details.
3. This is for the 400V. The 200V does not require a step-down transformer.

Compressed terminal width: 7.2mm (0.283 inch) max.
● Dynamic brake
When using a 11kW or larger servo amplifier, use these dynamic brakes if the servomotor must be suddenly stopped during a power failure or
when the protection circuit functions.
● Junction terminal block (MR-TB20)
All signals can be wired to this junction terminal block without a connection to CN1.
