NOTE 1: When MD0 is set and the input terminal SFT is turned ON, the data of all functions is locked. When MD2 is
set (stored), the data of all the functions is locked. During locking, no data can be changed. MD1, MD3
can set only the output frequency.
NOTE 2: Electronic thermal characteristic free setting current and frequency depends on the inverter rating.
