4-2 Function Mode •Below is the hysteresis of the frequency arrival signal: ON: (Set frequency - 1% of the maximum frequency) (Hz) OFF: (Set frequency - 2% of the maximum frequency) (Hz) 4 „ Constant Speed Arrival Output (01: FA1) •Outputs a signal when the output frequency has reached the level set in the frequency setting (F001, A020, and A220) or multi-step speed reference (A021 to A035). Functions Output frequency f on f off Set frequency f on :1% of the max. frequency f off :2% of the max. frequency (Example)(Max.
