Fieldbus Operation When
Fault
This parameter is accessible only if Fieldbus Control is previously set to On.
In case of fieldbus malfunction, for instance due to power loss or a broken cable,
this parameter allows for different (operations in case of a fault) reactions to the
fault.
Setting
Fieldbus fault reaction to trIP will make the softstarter trip on a fieldbus
fault. Selecting trIP makes reset of the fault necessary, in case of a tripping event.
When LocC is selected, the control of the softstarter will automatically switch from
fieldbus control to local control. The switch to local control will make
hard-wire
control possible. When the Fieldbus starts working again the control is automati-
cally switched back to the Fieldbus. There is a 10 second delay before controlling
the motor is possible.
