b39 / b40 (option card) S5 / S6 terminal MFIT Setting
Refer to b35 ~ b38
b42 Frequency UP / DOWN control (Motorized pot):
000 : Set frequency by this function will be stored when the inverter stops.
UP/DOWN function is not available in stop mode.
001 : Set frequency will be reset to 0Hz when the inverter stops.
002 : Set frequency will be stored when the inverter stops.
UP/DOWN function is available in stop mode.
1) b42 = 000, when a RUN command is ON, the inverter will accelerate to b45 then maintain
running at this set speed. When UP/DOWN terminal is ON, the inverter begins to
accelerate/decelerate until the signal goes OFF then it runs at this new speed etc.
When the RUN goes OFF, the inverter decelerates or coasts to stop according to the setting
of b92. The frequency at which the RUN signal is OFF will be stored in b45.
The UP/DOWN Key is not available at stop. The stored frequency cannot be changed by
UP/DOWN terminal, but can by changing the value of b45.
2) b42 = 001, the inverter will run from 0 Hz when run signal is applied.
UP/DOWN operation method is same as b45 = 000, but when next RUN signal is ON, inverter
will start from 0Hz.
3) b42 = 002. Same as when b45 = 001 but UP/DOWN is available while in stop mode.
