Stop
Turn off the servo-on command after the servo motor has stopped, and then switch the power off.
If any of the following situations occurs, the servo amplifier suspends the running of the servo motor and brings it to a stop.
Refer to the following for the servo motor with an electromagnetic brake.

Servo Amplifier Instruction Manual (Troubleshooting)
CC-Link IE Field Network connection
■Network disconnection procedure
Always make the servo-off status before turning off the system power and disconnecting the servo amplifier from the network.
Otherwise, [AL. 8D] may occur. For the detection conditions of [AL. 8D], refer to [Pr. PN06].
■Network configuration change
If the network configuration in the same network as the servo amplifier is changed, such as adding or disconnecting a slave
station, and adding a hub, all connected slave stations may be disconnected. Always make the servo-off status before
changing the network configuration. Otherwise, [AL. 8D] may occur or the servo amplifier may not be reconnected.

Stopping condition
The base circuit is shut off and the servo motor coasts.
The base circuit is shut off and the dynamic brake operates to bring the servo motor to a stop.
The servo motor decelerates to a stop with the command.
The servo motor decelerates to a stop with the command. With some alarms, however, the dynamic
brake operates to bring the servo motor to a stop.
Page 280 TROUBLESHOOTING
The servo motor decelerates to a stop with the command. [AL. E6 Servo forced stop warning] occurs.
EM2 has the same function as EM1 in the torque mode.
The base circuit is shut off and the dynamic brake operates to bring the servo motor to a stop.
Restrictions
Not compatible.
Not compatible.
Not compatible.
Not compatible. If the link start/stop function is used, [AL. 8D] may occur.
When the servo amplifier is set as a reserved station, [AL. 8D] will occur.
Even if the servo amplifier is set as a temporary error invalid station, [AL. 8D] may occur when the servo
amplifier is disconnected from the network. When setting the servo amplifier as a temporary error invalid
station, make the servo-off status.
Not compatible.
