7-3 Basic Functions (Group A)
7
• Setting the lower limit causes the inverter to output the frequency set in the 1st/2nd Frequency Lower
Limit (A062/A262) when 0 V or 4 mA is input to the frequency reference via analog input.
• When a frequency is input to the auxiliary frequency reference input (voltage reference) terminal FE
via positive/negative analog input, the lower limit on the forward/reverse side is judged as follows.
• When RUN Command Selection (A002) is set to 01 (Control circuit terminal block)

*1. To enable the switching to the 2nd/3rd control, allocate one of the Multi-function Input S1 to S8 Selection (C001
to C008) to 08 (SET) or 17 (SET3) and turn ON that terminal.
