Data range
The data is located in byte 4 to byte 7 of the parameter channel. This means up to 4
bytes of data can be transmitted per service. The data is always entered with right-jus-
tification; that is, byte 7 contains the least significant data byte (Data LSB) whereas byte
4 is the most significant data byte (Data MSB).
Incorrect execu-
tion of a service
The status bit in the management byte is set to signal that a service has been executed
incorrectly. If the received handshake bit is identical to the transmitted handshake bit,
the drive inverter has executed the service. If the status bit now signals an error, the
error code is entered in the data range of the parameter telegram. Bytes 4 through 7
provide the return code in a structured format (
