514 Fault Variables
You can directly clear an AxisLink failure on a virtual axis using a Reset
Fault block or by assigning a value of 0 to the appropriate
AxisLink_failed variable using an Equation block. However, this does not
automatically re-enable the virtual axis.
Drive Fault / Motor Thermal 1394
Drive_Fault applies to Compact, Integrated, and Basic controllers.
Motor_Thermal_1394 applies to 1394 controllers. Although the Terminal
Window or other display will continue to display Drive_Fault, even for
1394 controllers, the fault is actually a Motor_Thermal_1394 fault. The
information about Drive_Fault also applies to the Motor_Thermal_1394
fault.
Drive_fault is a logical (Boolean) variable which has values of:
• 1 (true) if the drive fault input for the specified axis was activated
• 0 (false) if not
In the Tag Explorer, select both Axis System Variables and the desired
physical axis, then select Drive_fault in the Tag Window.
When evaluated in an expression, the value of the Drive_fault variable
indicates whether a drive fault has occurred.
When Drive_fault = 1, Axis_fault = 5, Axis_status = 11, and Global_fault
= 5 if no other faults of higher priority are active.
A Drive_fault can only occur if the Compact, Integrated, or Basic motion
controller is configured to use the drive fault input.
A Motor_Thermal_1394 fault can only occur if the 1394 controller is
configured to use the motor thermal input.
See the Setup section of the Installation and Setup manual for your
motion controller for more information on configuring the drive fault and
motor thermal inputs.
