maximum value is 8.
The data description is as following. 

Store parameters (1010h) 

Save the value of the object into the relevant parameter by writing a specific signature to 1010-03h. So that, the servo can load the value of the parameter to the relevant object as an initial value.
The signature is saved. 

The relationship between Index and Parameter State by saving is described as below. 

 

In the case of 1010-03h, the data description is as following. 

NOTE: Commands that save objects to FRAM can only be executed when it is not in Servo ON state. Save Autonomously means you do not need to write save to the object when the slave saves the object value to FRAM.

The major version identifies a specific CANopen over EtherCAT (CoE) behaviour. If the CoE functionality is expanded, the major version has to be increased. The minor version number identifies different versions with the same behaviour.
(2): Serial number is not used (always 0).

 

13.2 PDO Mapping Objects
The CANopen over EtherCAT (CoE) protocol allows the user to map objects to process data objects (PDOs) in order to use the PDOs for real-time data transfer. 

Objects can be combined in PDO data via PDO Mapping and PDO Assignment.
The data description of PDO Mapping Objects is as following. 

The objects mapped to PDOs can be changed only when the EtherCAT (CoE) Network Module is in the PreOperational state.
There are 4 receiving PDOs (RxPDOs) and 4 transmit PDOs (TxPDOs). Each PDO Mapping can be assigned up to 8 objects, and the total assignment is not more than 32 bytes.
The procedure of PDO mapping is as following:
1. Disable the assignments between the Sync Manager and PDOs:
Set subindex 00h in objects 1C12h and 1C13h to 0.
2. Disable the assignments of PDOs:
Set subindex 00h in objects (1600h to 1603h) and (1A00h to 1A03h) to 0.
3. Set all of the mapping entries for the PDO mapping objects:
Set objects (1600h to 1603h) and (1A00h to 1A03h).
4. Set the number of mapping entries for the PDO mapping objects:
Set subindex 00h in objects (1600h to 1603h) and (1A00h to 1A03h).
5. Set the assignments between the Sync Manager and PDOs:
Set subindex 01h in objects 1C12h and 1C13h.
6. Enable the assignments between the Sync Manager and PDOs:
Set subindex 00h in objects 1C12h and 1C13h to 1.
