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.
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.
Trip on fieldbus fault or
automatically move to local
control on fieldbus fault
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:
• If HAnd is selected - The motor will stop and manual
reset is required.
• If Auto is selected - The motor will stop and automatic
reset is performed.
This parameter is accessible only if trIP is previously
selected for the parameter fieldbus Operation When
Fault.
Hand require manual reset of
fieldbus fault while Auto will
perform the reset automatically.
