Instruction Manual PSx3xxPN

Response identifier (drive

IO controller):
Response
identifier Function
0 No response
1 Transfer parameter value (word)
2 Transfer parameter value (double word)
4 Transfer parameter value (array, word)
5 Transfer parameter value (array, double word)
6 Transfer number of array elements
7 Cannot process request (with error number)
Subindex IND:
For requests and responses which refer to array elements, the field IND contains the
array subindex.
Parameter value PWE:
This field contains the numerical value which belongs to the related parameter.
When a request cannot be completed successfully (e.g. response identifier AK = 7),
the drive reports an error code according to the following table:
Error
code Meaning
0 Illegal parameter number
1 Parameter value cannot be modified
2 Minimum/maximum limit exceeded
3 Faulty subindex
4 No array
5 Incorrect data type
6 Setting not allowed (resetting only)
17 Request cannot be processed due to operating
state
18 Other error
When a write request is being completed successfully (e.g. request identifier AK = 2,
3, 7 or 8) the response contains the same data as a read request of this parameter.
The response identifier then is one of the values 1, 2, 4 or 5, depending on the data
type. The parameter number PNU, the index IND and the parameter value PWE are
the same as given in the request. Hence it is possible to check again that the drive
actually took over the requested values.
