SLC Fault Code
When a fault occurs within the SLC interface, the SLC_fault_code
variable determines the type of fault, as follows:
These faults apply to the 1394 Turbo, and do not apply to the SLC 500
CPU.
Resolver Loss Fault 1394
A resolver loss fault occurs when the 1394 motion controller detects that
one or more of the resolver signals, associated with the specified axis, is
missing.
In the Tag Explorer, select both Axis System Variables and the desired
physical axis, then select Resolver_loss_fault_1394 in the Tag Window.
Fault
Code
Type Description
0 No fault When no SLC faults have occurred, the variables SLC_fault
and SLC_fault_code both = 0
1 SLC process fault Occurs when the dedicated SLC process fault bit is set to 1
by the SLC application program. This allows the SLC
application program to generate a fault condition in the
1394 Turbo.
2 Power failure in
an SLC rack Occurs when one of the external SLC racks has a power
failure. Unlike the other faults, this fault is automatically
cleared when SLC rack power is restored
3 SLC interface
hardware fault Occurs when the SLC interface circuitry has failed power-up
diagnostics and is non-recoverable. If this fault persists after
power-cycle, the 1394 Turbo must be repaired.
