Parameter Adjustment Return Codes
If parameters are adjusted incorrectly, different return codes are sent back from the drive inverter
to the higher level automation system, providing detailed information about the cause of the error.
These return codes are generally structured according to DIN 19245 Part 2. A distinction is made
between the following elements
• Error class
• Error code
• Additional code
These return codes are described in detail in the Fieldbus Communications Profile Manual and are
not part of this documentation. However, the following special cases can arise in connection with a
PROFIBUS-FMS/DP:
5.1
Incorrect Service Code in the Parameter Channel
An incorrect service was specified for the management and reserved bytes when parameterizing
the drive inverter via the parameter channel. Table 17 shows the return code for this special case.
Table 17: Return code in the case of incorrect coding of bits 0 and 1 in the parameter channel
Error rectification:
Check bits 0 and 1 in the parameter channel.
5.2
Incorrect Specification of the Data Length in the Parameter Channel
When parameterizing via the parameter channel a data length not equal 4 data bytes was specified
in the Read or Write service. Table 18 shows the return code.
Table 18: Return code for incorrect length in the parameter channel (length
≠
4)
Error rectification:
Check bit 4 and bit 5 for the data length in the management byte of the parameter channel. Both
bits must be 1.
