5.11.5 Monitoring functions
For safe operation of the MOVITRAC
®
frequency inverter via communication interfaces,
additional monitoring functions have been implemented that trigger an operator-defined
drive function in the event of a bus fault. Two individual parameters are available for
each communication interface.
• Timeout interval
• Timeout response
This parameter defines an application-specific drive behavior in case of a communica-
tion error.
Timeout error mes-
sage / timeout
interval / timeout
response
The frequency inverter generates a timeout if no new data is received via the bus system
within a preset time frame (timeout interval). The timeout response can be set and de-
fines the malfunction (fault/warning) and the fault response of the drive.
