Byte 2: subindex
Additional addressing via the subindex is required for those codes that have a subcode (see
code table).
Example:
Code C0012 / subcode 2 addresses motor 2 acceleration time
Byte 3 / 4: index
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8
Service Subindex Index
High byte
Index
Low byte
Data 4 /
Error 4
Data 3 /
Error 3
Data 2 /
Error 2
Data 1 /
Error 1
The parameters or the Lenze codes are selected with these two bytes according to the
formula:
Index = 24575 - Lenze code number
Example:
The parameter C0012 (acceleration time) is to be addressed:
24575 - 12 = 24563 = 5FF3
hex
The entries for this example would be:
ƒ Byte 3: Index high byte = 5F
hex
ƒ Byte 4: Index low byte = F3
hex
Byte 5 - 8:
Parameter value (data) or error information (error)
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8
Service Subindex Index
High byte
Index
Low byte
Data 4 /
Error 4
Data 3 /
Error 3
Data 2 /
Error 2
Data 1 /
Error 1
The status of the (”status”) bit 7 in byte 1 (”service”) determines the meaning of this data
field:
Meaning of bytes 5 - 8 if
bit 7 = 0
bit 7 = 1
Parameter value (data 1 - 4 ) Error information (error 1 - 4) for an invalid access.
