mpiMotorPositionFeedbackOffsetGet

Declaration

	mpiMotorPositionFeedbackOffsetGet(MPIMotor motor, double *offset)
	Required Header: stdmpi.h

Description

mpiMotorPositionFeedbackOffsetGet retrieves the value stored in the encoder associated with motor and puts in the location pointed to by offset.

NOTE: If you are using an S200 drive, it requires an FPGA C0FE0036_0400_02_08 or later.

Return Values
MPIMessageOK
MEIMotorMessagePOSITION_FEEDBACK_OFFSET_UNSUPPORTED
MEIMotorMessagePOSITION_FEEDBACK_OFFSET_UNINITIALIZED

Sample Code

This code retrieves the offset value previously stored in a motor’s encoder and uses it to set the origin position for an axis.

/* creation of axis and motor objects assumed */
double offset;
mpiMotorPositionFeedbackOffsetGet(motor, &offset);
mpiAxisOriginSet(axis, offset);
