MPI_RESULT
   mpiMotorFeedbackRatio(MPIControl  control,
                         long        motorNumber,
                         long        feedbackNumber,
                         MPIRatio    *ratio);

Description

mpiMotorFeedbackRatio reads the feedback scaling from the controller and writes it into the structure pointed to by ratio. The feedback ratio can be configured with mpiMotorConfigSet. Feedback ratio scaling is useful for reducing feedback resolution to match previous machine configurations or when comparing multiple drive/motor combinations.

control	A handle to a control object.
motorNumber	An index to a motor.
feedbackNumber	An index to a feedback for the specified motorNumber.
*ratio	A pointer to a structure containing the feedback ratio
