558 Fault Variables
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_bus_loss_fault_1394 in the Tag Window.
Axis Motor Over Temp Fault 1394
An axis motor over temp fault occurs when the 1394 controller detects
that the thermal fault switch input to the control has opened. This
condition can occur when the motor gets too hot.
Axis_Motor_over_temp_fault_1394 is a logical (Boolean) variable, with
a value of:
• 1 (true) if the 1394 controller detects that the thermal fault switch
input to the control has opened (i.e., the motor gets too hot), and
• 0 (false) if not.
When Axis_Motor_over_temp_fault_1394 = 1, Global Fault = 5.
Clearing this fault clears Global Fault.
Clear this fault with Clear Axis Fault, set to clear Motor Thermal Fault.

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.
