5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
◼ Forward rotation/reverse rotation selection “DIR”
Only when F02 = 1 external signal, it is possible to change the run command direction with the “forward
rotation/reverse rotation “DIR” signal assigned to the digital input terminal.
◼ Self-hold selection “HLD”
Self-hold can be applied to “FWD” and “REV” with the “Self-hold selection “HLD”” signal assigned to the digital input
terminal. When “HLD” is ON, the inverter self-holds the “FWD” or “REV” signal, and when OFF, the hold state is
released.
◼ 2-wire operation
Two types of 2-wire operation can be configured regardless of whether “DIR” is used.
Forward rotation/stop: [FWD]
Reverse rotation/stop: [REV]
Run/stop: [FWD]
Forward rotation/reverse rotation: [DIR]
