Scaling Overview

Scaling refers to converting the transducer feedback into meaningful units. The RMC100 uses the Scale and Offset parameters to convert the transducer Counts into measurement units (position, pressure, force). For example, the counts returned by an analog position transducer must be converted to positions in order to be useful for control. In order to correctly convert the transducer feedback to useful units, the Scale and Offset must be calculated. RMC100 provides Scale/Offset Calibration utilities to assist you.

Calculating the Scale and Offset

The method of calculating the scale and offset parameters depends on the transducer type. See the scaling topic for the module you are using:

• MDT Scaling

• Quadrature Scaling

• SSI Scaling

• Analog Transducer Scaling

• Stepper Scaling

• Resolver Scaling

Scale/Offset Calibration Utilities

The following Scale/Offset Calibration utilities assist you in calculating the scale and offset parameters:

• Position Scale/Offset Calibration Utility

• Pressure Scale/Offset Calibration Utility

• Differential Force Scale/Offset Calibration Utility

• MDT Scale/Offset Calibration Utility

• SSI Scale/Offset Calibration Utility

• Quadrature Calibration Utility

Special Scaling Techniques

For specialized scaling techniques, see the Advanced Scaling topic. These techniques include scaling an axis such that speeds are expressed in minutes rather than seconds.
