Parameter Data Transfer - Lenze i55AE125B Manual

Parameter data transfer

For configuring and diagnosing the EtherCAT devices, the parameters are accessed by
•
means of acyclic communication.
Parameter data are transferred as SDOs (Service Data Objects).
•
The SDO services enable the writing and reading access to parameters, EtherCAT objects
•
and CiA 402 objects.
Objects
•
^ 388
Device profile CiA 402
•
The transfer of parameter data is usually not time-critical.
•
Parameter data are, for instance, operating parameters, motor data and diagnostic infor-
•
mation.
SDO return values
If an SDO request is evaluated negatively, a corresponding error code is output:
Index Description
0x00000000 No fault.
0x05030000 The state of the toggle bit has not changed.
0x05040000 SDO protocol time-out.
0x05040001 Invalid or unknown specification symbol for the client/server command.
0x05040005 The space in the main memory is not sufficient.
0x06010000 Unsupported access to an object.
0x06010001 Read access to a write-only object.
0x06010002 Write access to a read-only object.
0x06020000 An object is not available in the object directory.
0x06040041 An object cannot be mapped into the PDO.
0x06040042 The number and/or length of the mapped objects would exceed the PDO length.
0x06040043 General parameter incompatibility.
0x06040047 General internal incompatibility in the device.
0x06060000 The access has failed due to errors in the hardware.
0x06070010 The data type or the parameter length do not match.
0x06070012 Wrong data type: The parameter length is too big.
0x06070013 Wrong data type: The parameter length is too small.
0x06090011 A subindex is not available.
0x06090030 The value range for parameters is too big (only in case of write access).
0x06090031 The parameter value is too high.
0x06090032 The parameter value is too low.
0x06090036 The maximum value is smaller than the minimum value.
0x08000000 General fault.
0x08000020 Data cannot be transferred to the application or saved in the application.
0x08000021 Due to local control, the data cannot be transferred to the application or saved in the application.
0x08000022 Due to the current device state, the data cannot be transferred to the application or saved in the application.
0x08000023 The dynamic object directory generation has failed or no object directory is available.
