POINT
The on/off status of all devices in the servo amplifier are the status of the data
received at last. Therefore, when there is a device which must be kept on,
transmit data which turns the device on every time.
Each input device can be switched on/off. However, when the device to be switched off is in the external
input signal, also switch off the input signal.
