Timing chart of alarm occurrence

• [G] [WG]
In the torque 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.
• [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 with the forced stop deceleration, and MBR and ALM are turned off.
