Description

estopModify	See MPIAxisEstopModify.
inPosition	See MPIAxisInPosition.
master	This field defines the source of the position and velocities used as the master for cam motion. See Master Position Source.
masterCorrection	Specifies which axis provides the master position correction. A value of -1 stops any stops master corrections from being used. See Camming: Correctional Moves.
filterMap	bitmap indicating which Filter objects are mapped to the Axis. See MPIObject for more details.

Description

userLabel - consists of 16 characters that are used to label the axis object for user identification purposes. The userLabel field is NOT used by the controller.
*FeedbackDeltaPtr - Pointer to the position feedback delta, which is the difference in the feedback position between two sample periods, calculated by the controller.
PreFilter - an internal controller firmware structure that contains configurations for a command trajectory pre-filter for an axis.
Gear - an internal controller firmware structure that contains configurations for electronic gearing. Only servo axes (not steppers) are supported by electronic gearing.
GantryType - typedef enum { MEIXmpAxisGantryTypeNONE = 0, MEIXmpAxisGantryTypeLINEAR = 1, MEIXmpAxisGantryTypeTWIST = 2 } MEIXmpAxisGantryType; MEIXmpAxisGantryTypeNONE - is the default. No gantry enabled. MEIXmpAxisGantryTypeLINEAR - is used to add the axis' two feedback values. MEIXmpAxisGantryTypeTWIST - is used to subtract the axis' two feedback values. To see how to configure a gantry, please see gantry.c.
