2.2.1 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.
