5. 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.
Default value
LooC
6. Type of Operation for Reset of Fieldbus Fault
Select what operation shall be asserted if a fieldbus communication fault occurs. Manual or automatic options
are available. HAnd is the default value for reset of Fieldbus Fault:
Default value
HAnd

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 automatically
switched back to the Fieldbus. There is a 10 second delay before it
is possible to controlling the motor.
Setting range

• If HAnd is selected - The motor will stop and manual
