App. 11.1.3 Specifications
Dynamic brake which is built in 7 kW or smaller servo amplifiers is removed.
Take safety measures such as making another circuit for an emergency stop, alarm occurrence, and power
shut-off.
The following servo motors may function an electronic dynamic brake at an alarm occurrence.
Series Servo motor
HG-KR HG-KR053/HG-KR13/HG-KR23/HG-KR43
HG-MR HG-MR053/HG-MR13/HG-MR23/HG-MR43
HG-SR HG-SR51/HG-SR52
Setting the following parameter disables the electronic dynamic brake.
Servo amplifier Parameter Setting value
MR-J4-_B_-ED
MR-J4-_B_-RU
[Pr. PF06] _ _ _ 2
When [Pr. PA04] is "2 _ _ _" (default), the motor can be a state of forced stop deceleration at an alarm
occurrence. Setting "0 _ _ _" in [Pr. PA04] disables the forced stop deceleration function.

App. 11.2.3 Specifications
Indicates a servo amplifier of 11 kW to 22 kW that does not use a regenerative resistor as standard
accessory. When using any of these servo amplifiers, always use the MR-RB5R, MR-RB9F, MR-RB9T, MR-
RB5K-4, or MR-RB6K-4 regenerative option.
