Aerotech recommends that you do not use this parameter because it decreases system safety.

HARDWARE: This parameter does not apply when used with the GI4, the GL4, or the XL4s.

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.

Before you use the FaultMaskDisableDelay parameter, you must configure the parameters that follow:

Enable the BrakeSetup Parameter.
Set the BrakeDisableDelay Parameter to a nonzero value.

The FaultMaskDisableDelay parameter specifies the fault conditions that obey the BrakeDisableDelay parameter. The FaultMaskDisableDelay parameter is a bit mask where each bit corresponds to a specific axis fault.

By default, if an axis is disabled because of a fault condition, the BrakeDisableDelay parameter is ignored and the axis is disabled at the same time that the brake is engaged. If this behavior is not applicable for a given fault, you can set the corresponding bit in the FaultMaskDisableDelay parameter. When you set the corresponding fault bit, the axis fully engages the brake and then delays by the interval that is specified for the BrakeDisableDelay parameter. Then the axis disables.

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.
3	0x00000008	AxisFault.CcwEndOfTravelLimitFault	CCW/Negative End-of-Travel Limit Fault	The axis encountered the counter-clockwise (negative) end-of-travel limit switch.
4	0x00000010	AxisFault.CwSoftwareLimitFault	CW/High Software Limit Fault	The axis was commanded to move beyond the position specified by the SoftwareLimitHigh Parameter parameter.
5	0x00000020	AxisFault.CcwSoftwareLimitFault	CCW/Low Software Limit Fault	The axis was commanded to move beyond the position specified by the SoftwareLimitLow Parameter.
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.
9	0x00000200	AxisFault.HallSensorFault	Hall Sensor Fault	The drive detected an invalid state (all high or all low) for the Hall-effect sensor inputs on this axis.
10	0x00000400	AxisFault.MaxVelocityCommandFault	Maximum Velocity Command Fault	The commanded velocity is more than the velocity command threshold. Before the axis is homed, this threshold is specified by the VelocityCommandThresholdBeforeHome Parameter. After the axis is homed, this threshold is specified by the VelocityCommandThreshold Parameter.
11	0x00000800	AxisFault.EmergencyStopFault	Emergency Stop Fault	The emergency stop sense input, specified by the EmergencyStopFaultInput Parameter or SoftwareEmergencyStopInput Parameter, was triggered, or the controller detected a fault condition in the Safe Torque Off (STO) hardware.

17	0x00020000	AxisFault.MotorTemperatureFault	Motor Temperature Fault	The motor thermistor input was triggered, which indicates that the motor exceeded its maximum recommended operating temperature.
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.
19	0x00080000	AxisFault.EncoderFault	Encoder Fault	The encoder fault input on the motor feedback connector was triggered.

24	0x01000000	AxisFault.MarkerSearchFault	Marker Search Fault	The distance that the axis moved while searching for the marker exceeded the threshold specified by the MarkerSearchThreshold Parameter parameter.

30	0x40000000	AxisFault.InternalFault	Internal Fault	The drive encountered an internal error that caused it to disable. The Internal Fault cannot be acknowledged. You must reset the controller to clear this fault. For information, use the Global Technical Support Portal to contact Aerotech Global Technical Support.
