• When an alarm that is not subject to the converter main circuit stop occurs
When connecting multiple MR-J5D_-G_ to one MR-CV, set [Pr. PC46.2 Protection coordination multiple
connections selection] to "1".
When an alarm is detected, MBR is turned off, and the servo motor is stopped using the dynamic brake and electromagnetic
brake.
When an alarm that is not subject to the converter main circuit stop occurs in the MR-J5D_-G_, the servo motor stops only for
the axis where the alarm occurred. Operation of other MR-J5D_-_G_ connected with the protection coordination cable can
continue.
When the corresponding axis stop alarm occurs in the MR-J5D2-_G_ or the MR-J5D3-_G_, only the axis on which the alarm
occurred will be in the operation status explained in this section. Operation of the axes where no alarms are occurring can
continue.
For the alarms that are subject to the converter main circuit stop and the corresponding axis stop alarms, refer to "List of
alarm No./warning No." in the following manual.
