Clear this fault with a Reset Fault block, set to Reset 1394.
Important: Do not use an Equation block to clear this fault. The Reset
Fault block not only resets this variable to zero, it also resets
the Drive OK Relay inside the 1394 system module. This
relay must be reset before the System Bus can be reapplied.
In the Tag Explorer, select both Axis System Variables and the desired
physical axis, then select Axis_power_fault_1394 in the Tag Window.
Axis Bus Loss Fault 1394
Axis_bus_loss_fault_1394 is a logical (Boolean) variable, with a value
of:
• 1 (true) if an enabled 1394 axis module detects that the bus voltage
level has fallen below acceptable limits, and
• 0 (false) if not.
When Axis_bus_loss_fault_1394 = 1,
Axis_module_hard_fault_1394 = 1, and Drive_hard_fault_1394 = 1.
Clearing this fault clears Drive_hard_fault_1394.

ATTENTION: A hard fault is a serious condition! Be
certain to correct the underlying cause of this fault,
before clearing the fault and reactivating the drive.
