■Stopping with dynamic brake
When an alarm is detected, MRB and ALM are turned off, and the servo motor stops using the dynamic brake and
electromagnetic brake.
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.
When the all-axis stop alarm occurs in the MR-J5D2-_G_ or the MR-J5D3-_G_, all axes will be in the operation status
explained in this section.
For details on the corresponding axis stop alarm and the all-axis stop alarm, refer to "List of alarm No./warning No." in the
following manual.
