Baud rate setting

9.6.4 Baud rate setting
At the class 1 DP master, the desired baud rate is set. All masters at the bus must be set to the
same baud rate.
The parameters for the baud rate of the device are described below.
Details
The inverter detects the baud rate automatically.

Monitoring

The inverter can give a parameterisable response to various PROFIBUS errors.
The parameters for setting network monitoring functions are described below.
Details
The following table lists the PROFIBUS errors that can be set for a response.
Event
Communication to the PROFIBUS master is continuously interrupted.
Data exchange via PROFIBUS has been terminated.
The inverter has received invalid configuration data from the master.
An error has occurred during the initialisation of the PROFIBUS interface.
The process data received are invalid.

Info
Display of the active baud rate.
Automatic baud rate detection active.
Display of the current state of the watchdog state machine (WD-STATE).
The inverter (slave) is able to detect the baud rate automatically.
After detecting the correct baud rate, the inverter (slave) status changes
to BAUD_CONTROL, and the baud rate is monitored.
The DP_CONTROL state serves to the response monitoring of the master.

Info
Display of the watchdog monitoring time specified by the master.
• Monitoring starts with the arrival of the first telegram.
• When a value of "0" is displayed, the monitoring function is deactiva-
ted.
• A change in the watchdog monitoring time in the master is effective
immediately.
