8.3.1.11 Programming of write requests
Procedure
1. Define the user data range of the controller (define the location of the user data in
the host system).
Observe manufacturer−specific data.
2. Enter the code of the desired parameter into the "code" field (output data).
3. Enter parameter value into the "Data/Error" field.
4. Job identification / service = write request
5. Check whether index and subindex correspond with the job and whether the job
identification is
Ø 0:
– If the criteria are fulfilled, the desired master data from the field "Parameter
value" are accepted by the controller.
– If these criteria are not fulfilled, the response identifier is negative (high nibble of
byte 1 = 7
hex
). In this case, the error information can be read out from the entry in
the low word.
Example:
The controller acceleration time (C0012) is to be set to 20 s.
ƒ Job identification (high nibble in byte 1)
Transmit simple parameter value: "1"
ƒ Code: (low nibble in byte 1 and byte 2)
C0012: 12 = 0C
hex
ƒ Lenze subcode (byte 3):
Subindex = 0, as there is not subindex under code C0012.
ƒ Bytes 5 ...8: Data
Data 1 ... 4 = 20 s x 10000 = 200000 = 00030D40
hex
Result:
ƒ Request telegram from master to drive:
