Physical dimensions and sizes need to be converted into the device internal units, requiring a number of different factors. This chapter describes how these factors influence the system, how they are calculated and which data is needed to build them.
8.1Relationship between Physical and Internal Units
The factors defined in the factor group determine a relationship between the Elmo drive internal units and the application physical units. The factors are a result of the calculation of two parameters – called dimension index and notation index – which are defined Appendix A and Appendix B. One parameter indicates the physical dimensions, and the other indicates the decimal exponent for the values. These factors are directly used to normalize the physical values.
The
8.2Functions and Limits
Factors cannot be set while the drive is in OPERATION ENABLE state.
Divisors cannot be set to 0. An abort message with abort code 0609 0030 will be transmitted.
Values are truncated to the nearest integer.
