3 BASIC FUNCTION
3.14 Alarm function
Timing chart at alarm occurrence
• MR-J5-_G_/MR-J5W_-_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.
• MR-J5-_A_
In the torque mode, the forced stop deceleration function cannot be used.
When using the forced stop deceleration function
When [Pr. PA04.3 Forced stop deceleration function selection] is set to "2" (Forced stop deceleration function
enabled).
■
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.
*1 The model speed command is a speed command generated in the servo amplifier for forced stop deceleration of the servo motor.
