Adjust the relationship between the extemal frequency oonmand and th€ inverrer oulput frequency.
: Voltage command (O,L)
: Cunent command (OI-L)
This function is factory set to tie appropriate posilion. lfahis setting is changed unnecessarily, th€
correct relationsbip between the ertemal ftequency command and output frequency is no longer
mainlained. This will result in poor control perfom nce. Adjust the setting oI this filnction only
when lhe output frequency dlfs not conform to the extemal command.
