Details of Functions
•
Normal Mode
This mode allows you to assign up to 350 bytes of input data.
The assigned input data (except for I/O data) are divided and refreshed in order across more than
one cycle.
•
Detection Level Speed Priority Mode
This mode allows you to assign up to 108 bytes of input data.
All assigned input data are refreshed every cycle.
The refresh cycle depends on the number of Sensors, amount of assigned data, and whether
input filters and Dummy Sensors are used.
The refresh cycle for data in the Sensor Communications Unit for each mode is given in the
following table.
•
Free-Run Mode
•
DC Mode
The refresh cycle is the same as the output cycle of the Sync0 signal.
The PDO communications mode is set through SDO communications.
The applicable index is 300C hex.
For the set values, refer to the description of object index 300C hex (TxPDO Mapping Mode) in "A-1
Object Dictionary" on page A-2.
