Maximum number of synchronized axes in each PLC type
There are limit on the minimum cycle time for each PLC type and limit on the number of servo drives can be connected for each PLC type based on the cycle time configured. Adapt the cycle time or PLC type accordingly to avoid error messages during program download.

The table shows the maximum allowed possible axes that can be configured in Automation Builder.
However, the actual number of axes usable in a specific real application can be lower based on:
-
PLC load created by the axis type
-
PDO configuration
-
application/motion program
-
other EtherCAT parameters
These limits are based on the EtherCAT master cycle time configured in the EtherCAT master. The “Number of axes” is counted in Automation Builder are based on the axis configured, therefore PTO axis also counted in case if configured in the AC500-eCo Pro PLC.
More axis can be used by:
-
Increasing the EtherCAT cycle time to accommodate a higher “Number of axes” in the same PLC type.
-
Choosing a higher PLC type.
The “Motion Solution” window can be used to see how many axes are supported and how many are already used for the particular PLC type for the EtherCAT master cycle time configured by checking the slider at the bottom of the “Motion Solution Wizard” overview page:
