5-4-5 Multiple PDO Mapping
*1 A maximum of 10 objects in total can be mapped to the Receive PDO mapping.
*2 A maximum of 11 objects in total can be mapped to the Transmit PDO mapping.
Precautions for Correct UsePrecautions for Correct Use
• The communications cycle you can set varies depending on the total size of mapped objects.
Refer to A-1-3 Communications Cycles and Corresponding Modes of Operation on page A-5
for details.
• If the size of the mapped objects exceeds the maximum total size, a Function Setting Error
(Error No. 93.4) will occur.
• If the number of the mapped objects exceeds the maximum allowed number, a Function
Setting Error (Error No. 93.4) will occur.
