MarkerSearchThreshold Parameter
Default Value: 0.0
Minimum Value: 0.0
Maximum Value: None
Units: distance
Type: double
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.
IMPORTANT: This parameter applies only during homing and when you use a HomeType Parameter setting that includes the encoder maker.
Use the MarkerSearchThreshold parameter to define the maximum distance that the axis is allowed to travel while it searches for the marker during a home cycle. If the motion of the axis exceeds this distance then a marker search fault is generated.
This parameter is intended to prevent unexpected behavior or damage to the system in the event of a missing marker signal. For a rotary axis with unlimited travel, you should set this parameter to slightly more than one revolution, because the marker signal should occur for every revolution. For a linear axis or a limited-travel rotary axis, you should set this parameter to slightly more than the distance between the end-of-travel limit and the marker location.
IMPORTANT: If you set the value of this parameter to zero, it will disable the marker search fault.
When you reference this parameter in an AeroScript program, the parameter value is in the units specified by the unit mode of the task. If the task is in primary units mode, this parameter is in primary units. If the task is in secondary units mode, this parameter is in secondary units.
