Timing chart for alarm occurrence

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.
