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 param-
eter 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. Select-
ing 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 possi-
ble. When the Fieldbus starts working again
the control is automatically switched back to
the Fieldbus. There is a 10 second delay before
it is possible to controlling the motor.
