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 | |
| MPIMotorMessagePOSITION_FEEDBACK_OFFSET_UNSUPPORTED | |
| MPIMotorMessagePOSITION_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);
