Parameter Adjustment Return Codes
If parameters are adjusted incorrectly, different return codes are sent back from the drive inverter
to the parameterizing master, providing detailed information about the cause of the error. These
return codes are generally structured according to EN 50170 V2 / 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 Profile User Manual and are not part of
this documentation. However, the following special cases can arise in connection with a PROFI-
BUS-FMS/DP:
5.1
Incorrect Service Code in the Parameter Channel
An incorrect service was specified when setting the inverter parameters via the parameter channel.
Only the READ and WRITE services are supported. The following table shows the return code for
this special case.
Error rectification:
Check bits 0..2 in the management byte of the parameter channel. Only the entries 001
bin
for the
READ service and 010
bin
for the WRITE service are permitted.
5.2
Incorrect Specification of the Data Length in the Parameter Channel
When setting parameters via the parameter channel a data length not equal 4 data bytes was spec-
ified in the READ or WRITE service. The following table shows the return code.
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.
