Transmission data configuration

Up to 32 axes can be connected to the bus. Therefore, to determine the destination servo amplifier of data communication, a
station No. is added to the command, data No., etc. Set one station number to one servo amplifier using servo parameters.
Transmission data is enabled for the servo amplifier of the specified station No.
When "*" is set as the station No. to be added to the transmission data, the transmission data is enabled for all servo
amplifiers being connected. However, when return data is required from the servo amplifier in response to the transmission
data, set "0" as the station No. of the servo amplifier which must provide the return data.
