Input device on/off
Each input device can be switched on/off via communication. However, when the device to be switched off is in the external
input signal, switch off the input signal as well. The on/off states of all devices in the servo amplifier are the states of the last
received data. Therefore, when there is a device which must be kept on, transmit data which turns the device on every time.
Transmit the command [9] [2] + data No. [6] [0] + data.
The bit is the same as that of [1] [2] + [0] [0].
