The FMS object “Min Tsdr” can then be used to read or write the min TSDR bus parameter directly.
Table 12 shows the definition of the min TSDR object. When changing min TSDR remember that
when the drive inverter is powered up again (mains supply and 24 V supply ON/OFF), however, the
min TSDR default value will again be operative.

Important
Changing min TSDR can cause major malfunctions across the entire PROFIBUS network and
should therefore only be done by PROFIBUS experts. As a rule, the default setting according to DIN
19245, which is set using the DIP switch on the option pcb, is more than adequate. These DIN
19245 default values guarantee stable operation of the PROFIBUS network.
4.2.4 “DP Station Diagnosis” Object
The diagnostic messages of the drive inverter in DP mode are stored in this object. The DP master
can retrieve these diagnostic data using the DP service DDLM_SlaveDiag. An FMS master can
retrieve these diagnostic messages via this communications object using the FMS service Read.
Table 13 provides a definition of this communications object.
