Caution
The emergency stop command forcibly stop the motor with the inverter unit key operation even if the
command mode is not set to panel operation mode. This command cannot be prohibited with the
command mode selection. When executed, the emergency stop will be regarded as a trip and will be
recorded as a past fault.
