memorized frequency
Range: 0.00Hz-Maximum frequency Default:0.00Hz
The starting frequency output when inverter runs in UP/DW control mode. It is enabled only
[F-07]
LED ten digit
has been set for 1 or 2 .
When the
[F-07]
LED ten digit sets for 1,
[F-71]
parameters will memorize the last UP and DOWN control
momentary frequency. User can review and modify the last stop momentary frequency via
[F-71]
in stop status.
When the
[F-07]
LED ten digit sets for 2, the starting frequency can be preset via
[F-70]
parameters in UP/DW
control.
8.3. Special Function Parameters
User define V/F curve:
User can define 1st, 2nd , 3rd , 4th , 5th point of V/f curve percentage for output voltage reference, corresponding to
F1/F2/F3/F4/f frequency point separately. User also can define1st, 2nd , 3rd , 4th , 5th of frequency point to
correspond V1,V2, V3, V4, V5.
