modes using MFIT
000: When using the Up / Down command, the set frequency will be
stored after the inverter stops.
The Up / Down function is not available in stop mode.
001: When using the Up / Down command, the set frequency will be
reset to 0Hz after the inverter stops.
002: When using the Up / Down command, the set frequency will be
stored after the inverter stops.
The Up / Down function is available in stop mode.
1) C40=000: When the RUN signal is ON, the inverter will accelerate to the value set by F28 then
continue to run at the set commanded speed. When Up / Down terminal is activated, the inverter
begins to accelerate/decelerate until the Up / Down command is removed. The inverter then runs
at that set speed.
When the RUN signal is OFF, the inverter decelerates to STOP (or coasts to stop) according to
the setting of (F09) and the last output frequency, will be stored in (F28).
The Up / Down Key is
unavailable
in stop mode. The stored frequency can not be changed by at
The Up / Down terminal, but can be changed by the content of F28 via the keypad.
2) C40=001: The inverter will run from 0Hz when the run signal is applied. The Up / Down
operation is same as C40=000, except when restarted, the inverter always ramps up from 0Hz.
3) C40=002: Same as for C40=001 except the Up / Down is available while in stop mode to adjust
the set frequency.
