Timing Chart At Alarm Occurrence (Mr-J5D_-_G_) - Mitsubishi Electric MELSERVO-J5 User Manual

Timing chart at alarm occurrence (MR-J5D_-_G_)

In the torque mode and continuous operation to torque control mode, the forced stop deceleration function
cannot be used.
When the servo motor is at a stop due to an alarm or other factors, commands from the controller are not
accepted. When restarting the operation in the cyclic synchronous position mode, confirm the position
command.
When connecting multiple MR-J5D_-_G_ to one MR-CV, set [Pr. PC46.2 Protection coordination multiple
connections selection] to "1".
When using the forced stop deceleration function (when MR-CV and MR-J5D_-_G_ are
connected one-to-one)
• When [Pr. PA04.3 Forced stop deceleration function selection] is set to "2" (Forced stop deceleration
function enabled).
• For a machine in which multiple axes are connected to each other, such as a tandem configuration, set [Pr.
PA04.3] to "0" (Forced stop deceleration function disabled). If an alarm occurs with the forced stop
deceleration function disabled, the servo motor will stop with dynamic brake.
■Stopping with forced stop deceleration function
When an alarm is detected, the servo motor stops using forced stop deceleration and MBR and ALM are turned off.
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.
