5 SDO service
5.1 General
The device supports 1 SDO server (Expedited read/write, segmented read)
5.2 Save/load parameters
The device supports saving parameters to a non-volatile memory.
5.2.1 Save
Writing “save” to 0x1010-x saves the corresponding objects to the non-volatile memory. After a reset or power-on, the
parameters are loaded from the non-volatile memory. The SDO request to 1010h-x is answered after saving.
5.2.2 Load
Writing “load” to 1011h-x restores the corresponding objects. The parameters are restored after a reset or power-on.
5.2.3 Safe non-volatile operation
To ensure safe non-volatile operation, the time between access object 1010h-x or 1011h-x and a reset or power-on has
to be at least 600 ms.
5.2.4 Side effect
Save/Load operations interrupt the updating of position.

6 PDO Service
6.1 General
The device supports TPDO1 and TPDO2. PDOs are only transmitted in NMT operational mode.
6.2 PDO transmission types
The following transmission types are supported (object 180x-2):
Synchronous transmission (1-240)
Asynchronous transmission (255)
Manufacturer transmission (254)
Both PDOs support all transmission types.
Transmission type 255 and 254: The PDO is transmitted timer driven. The time interval between 2 PDOs can be
adapted in the object 180xh-5
Transmission type 1-240: The PDO is transmitted after the n-th sync frame.
Transmission type 1: The PDO is transmitted after one sync frame.
Transmission type 2: The PDO is transmitted after two sync frames.
etc.
6.3 COB-ID
The COB-ID for both PDOs is changeable (in Object 180xh-1)
The format of the TPDO is:

where P is the actual position value in 0.1mm or other scale (depending on the resolution settings) and the suffixes ’a’
and ’b’ refers to channels ’a’ and ’b’ respectively.
Interpretation example
Considering a resolution of 0.1mm:
P0 = 0x10, P1 = 0x27
It means P = 0x00002710 (10000 decimal) = 1000mm
The channel ’b’ is represented in a similar way (but typically in a reverse order so, in the zero position, channel ’b’ is
4700mm and at FS his value is 0).

7 Emergency Service
7.1 General
If there is an error on the device, the device commits an emergency message and sets the corresponding bits in the error
register (Object 1001h).
Error codes are accessible by the error field (object 1003h-x). A history of maximal 8 error codes is stored in the error
field.
7.2 COB-ID
The COB-ID for the emergency message can be modified in object 1014h.
Default Value: 80h + node ID
Changes will be applied immediately.
The COB-ID is stored internally as a difference to the default COB-ID. Example:
Node ID: 4 COB-ID Emergency: 84h (Default value)
COB-ID Emergency: 87h (Changed by user)
Node ID: 9 COB-ID Emergency: 89h (Adapted automatic)

Communication errors are indicated if the internal CAN message buffers are overflowed or there are malformed CAN
frames on the bus. After a communication error the device changes to pre-operational mode.
7.4.2 Generic error
A generic error is indicated for all other errors.
An encoder specific alarm or warning will also cause a generic error.
