Communications 7-9
Reference/Feedback The SMC-Flex does not offer the analog Reference feature. The
analog Feedback feature is supported and will provide Parameter 1,
Current in Phase A, automatically as the feedback word.
Parameter Information A complete listing of the SMC-Flex parameters is located in
Appendix B.
Scale Factors for PLC
Communication
The parameter values stored and produced by the SMC-Flex through
communication are unscaled numbers. When reading or writing
values from a PLC image table, it is important to apply the proper
scaling factor, which is based on the number of decimal places.
Read Example
Parameter 11; Power Factor — The stored value is 85. Since this
value has two decimal places, the value should be divided by 100. The
correctly read value is 0.85.
Write Example
Parameter 46; Motor FLC — The value which is to be written to
the SMC is 75 A. Since this value has one decimal place, the value
should be multiplied by 10. The correctly written value is 750.
