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.
