14 - 6
14.3 Protocol
14.3.1 Transmission data configuration
Since up to 32 axes may be connected to the bus, add a station No. to the command, data No., etc. to
determine the destination servo amplifier of data communication. Set the station No. to each servo amplifier
using the parameters. Transmission data is enabled for the servo amplifier of the specified station No.
When "*" is set as the station No. added to the transmission data, the transmission data is enabled for all
servo amplifiers connected. However, when return data is required from the servo amplifier in response to
the transmission data, set "0" to the station No. of the servo amplifier which must provide the return data.
