2. Reading from sub-index
Subindex (Read)
Byte 0 1 2 3 4 5 6 n
ACK 00 Parameter figure
Contents
Parameter number +
data set x 1000
NAK 00 Error code undefined
After parameter number, data set and parameter value have been written per SDO
Write, the corresponding sub-index is read back with SDO Read.
In the reply in the reading of sub-index, the frequency inverter states whether the
writing process was successful (ACK) or whether an error occurred (NAK). If an error
occurred, a corresponding error code is reported.
SEL = 2
ENQ = 5
ACK = 6
NAK = 15
Access to a parameter figure is done by stating the parameter number and the data
set.
Example: Parameter number = 370, data set = 3
Byte 0/1 = 370 + 3*1000
Byte 0/1 = 3370
8.6.2 Error code list
Read/Write
Error code Meaning
1 Inadmissible parameter value
2 Inadmissible data set
3 Parameter not readable
4 Parameter not write-capable
5 Reading error, EEPROM
6 Writing error, EEPROM
7 Check sum error EEPROM
8 Parameter cannot be changed while
the drive mechanism is running
9 Values of the data sets differ
10 Parameter has the wrong type
11 Unknown parameter
15 Unknown error
Note: If the ID ENQ or SEL is not stated in SDO Write, the report is done with
NAK and error code = 0.
