■Stopping with dynamic brake
When connecting multiple MR-J5D_-G_ to one MR-CV, set [Pr. PC46.2 Protection coordination multiple
connections selection] to "1".
• When an alarm that is subject to the converter main circuit stop occurs
When an alarm is detected, MBR and CVST are turned off, and the servo motor is stopped using the dynamic brake and
electromagnetic brake.
When an alarm that is subject to the converter main circuit stop occurs in an MR-J5D_-_G_, the other MR-J5D_-_G_
connected with the protection coordination cable also stops the servo motor.
For the alarms that are subject to the converter main circuit stop, refer to "List of alarm No./warning No." in the following
manual.
