*For (-E) models.
nAdjusting Analog Frequency Reference Using Parameters
The frequency reference is input from the control circuit terminals using analog voltage and current.
If using frequency reference terminal A1 as an input terminal, perform adjustments using parameters H3-02
and H3-03. If using multi-function analog input terminal A2 as a frequency reference terminal, perform
adjustments using H3-10 and H3-11.
