IMPORTANT: The controller generates an axis fault only if you set the corresponding bit in the FaultMask Parameter. When an axis fault is generated, you can configure what the axis does by changing the state of the corresponding bit in the FaultMaskDecel Parameter, the FaultMaskDisable Parameter, and the FaultMaskDisableDelay Parameter.

The FaultMask parameter specifies the axis fault conditions that the controller can detect. This parameter is a bit mask where each bit corresponds to a specific axis fault.

For most faults, the controller reports the fault condition only if the axis is enabled. But the controller can report the Emergency Stop fault when the axis is disabled. If you set the Feedback Fault Reporting setting of the FaultSetup Parameter to Always, then the controller can also report the FeedbackInput0 and FeedbackInput1 faults when the axis is disabled.

You can configure what the axis does for each fault condition by using the settings in the table that follows.

Table: Axis Fault Behavior

Fault Behavior	Parameter Settings
Not monitored	In FaultMask, clear the corresponding fault bit. FaultMaskDecel is not applicable. FaultMaskDisable is not applicable.
Decelerate to a controlled stop	In FaultMask, select the corresponding fault bit. In FaultMaskDecel, select the corresponding fault bit. In FaultMaskDisable, clear the corresponding fault bit.
Disable immediately	In FaultMask, select the corresponding fault bit. In FaultMaskDecel, clear the corresponding fault bit. In FaultMaskDisable, select the corresponding fault bit.
Decelerate to a controlled stop, then disable	In FaultMask, select the corresponding fault bit. In FaultMaskDecel, select the corresponding fault bit. In FaultMaskDisable, select the corresponding fault bit.

If an axis is in a fault condition, the axis completes the action that you specify in the FaultMask, FaultMaskDecel, and FaultMaskDisable parameters. Before normal operations can continue, you must recover from the axis fault by doing the steps that follow:

Correct the condition that caused the controller to generate an axis fault.
Acknowledge the fault condition by doing one of the steps that follow in the Configure tab of Automation1Studio:

Click the Acknowledge All button or issue an AcknowledgeAll() function to clear all the axis faults on the controller.
Issue the FaultAcknowledge() function to acknowledge the axis faults on the axis that you specify.

Examining Axis Faults

For more information about an axis fault that the controller generates, do one of the options that follow:

Look at the axis fault in the Axis Dashboard or the Studio notification bar. The faults show in red text.
In your AeroScript program, use StatusGetAxisItem($axis, AxisStatusItem.AxisFault) to read the values of the Axis Fault.
For advanced diagnostics information about the axis fault, use the Fault tab in the Status Utility.

For more information about axis faults, refer to Fault and Error Functions.

Fault Mask Bit Descriptions

Table: Axis Fault Bit Descriptions

Bit	Value	AeroScript Constant	Name	Description
0	0x00000001	AxisFault.PositionErrorFault	Position Error Fault	The absolute value of the difference between the position command and the position feedback exceeded the threshold specified by the PositionErrorThreshold Parameter.
1	0x00000002	AxisFault.OverCurrentFault	Over Current Fault	The average motor current exceeded the threshold specified by the AverageCurrentThreshold Parameter and AverageCurrentTime Parameter.
2	0x00000004	AxisFault.CwEndOfTravelLimitFault	CW/Positive End-of-Travel Limit Fault	The axis encountered the clockwise (positive) end-of-travel limit switch.

6	0x00000040	AxisFault.AmplifierFault	Amplifier Fault	The amplifier for this axis exceeded its maximum current rating, the bus voltage exceeded the BusOvervoltageThreshold Parameter on a PWM drive, the BusOvervoltage hardware signal was triggered, or the amplifier had an internal error.
7	0x00000080	AxisFault.FeedbackInput0Fault	FeedbackInput0 Fault	The drive detected a problem with the feedback device specified by the PrimaryFeedbackType Parameter and FeedbackInput0 Parameter . Or, the drive detected an invalid position feedback configuration.
8	0x00000100	AxisFault.FeedbackInput1Fault	FeedbackInput1 Fault	The drive detected a problem with the feedback device specified by the AuxiliaryFeedbackType Parameter and FeedbackInput1 Parameter. Or, the drive detected an invalid velocity feedback configuration.

18	0x00040000	AxisFault.AmplifierTemperatureFault	Amplifier Temperature Fault	The amplifier temperature is not within the operating range. For most HyperWire drives, this fault occurs at temperatures greater than 75 °C. On the iXA4 and XA4, this fault occurs at temperatures greater than 100° C. If the temperature sensor reading is invalid or below 0° C, the drive reports a temperature of 1000° C. This reading usually identifies a defective sensor that must be repaired at the factory. On the iXC6e and XC6e, this fault also indicates when the calculated shunt resistor temperature based on the ShuntNormalizedTemperatureFactor Parameter and the ShuntThermalTimeConstant Parameter is more than 200 °C.

You must reset the controller to clear this fault. For information, use the Global Technical Support Portal to contact Aerotech Global Technical Support.
