Settings
When start frequency is higher than the min. output frequency, drives' output will be from start
frequency to the setting frequency. Please refer to the following diagram for details.
Fcmd=frequency command,
Fstart=start frequency (Pr.01-09),
fstart=actual start frequency of drive,
Fmin=4th output frequency setting (Pr.01-07/Pr.01-41),
Flow=output frequency lower limit (Pr.01-11)
Fcmd>Fmin and Fcmd<Fstart:
If Flow<Fcmd
If Flow>=Fcmd, drive will run with Fcmd firstly, then, accelerate to Flow according to
acceleration time.
The drive's output will stop immediately when output frequency has reach to Fmin during
deceleration.
