3-2 Transmission of cyclic data
3-2-1 Cyclic transmission area
Use bytes 2 to 7 in command/response data block or bytes 24 to 31 in the 32-byte mode, as cyclic transmission area for
real-time data such as command position and feedforward data.
Use bytes 12 to 15 (Command_Data3) in command data block as cyclic transmission area by using Pr.7.35 (RTEX
command setup 1). For details, refer to 7-7.
Use bytes 8 to 15 (Reponse_Data2/3) in response data block, or bytes 20 to 23 (Sub_Response_Data1) in the 32-byte
mode, as cyclic transmission area by using Pr.7.30 to Pr.7.32 (RTEX monitor select 2/3/4). For details, refer to 4-3-1.
There is no special transmission procedure for the cyclic command area data. The servo driver will reflect the received
cyclic command data in the control at once, and will return the latest value of the cyclic response data.
