Diagnosis Using the Fieldbus Monitor Parameters
The MOVITRAC
®
31.. frequency inverter provides a large amount of diagnostic information for
fieldbus operation. In addition to the fieldbus parameters, diagnostic tools also include menu range
P070 - P079, which contains the fieldbus monitor parameters. These parameters allow simple
diagnosis of the fieldbus application from the inverter.
This section will primarily explain the fieldbus monitor parameters. The fieldbus parameters will only
be given again for the sake of completion, since they are to be regarded in direct connection with the
fieldbus monitor. Further information regarding parameters P560 - P572 can be found in the previous
sections.
The following table illustrates the adjustable fieldbus parameters (P560 - P572) as well as the fieldbus
monitor parameters (P070 - P079).

Diagnosis of Process Output Data
Faulty operation of the inverter can normally be traced back to a faulty application program. This
means that false control information or setpoints are occasionally sent to the inverter from the
higher-level control. As a result, it is often helpful to know what control information and setpoints
the inverter is receiving. User-friendly fieldbus master interface connections, e.g. rows of LEDs on
the front cover, offer simple facilities for diagnosis of individual fieldbus process data.
