For applications, in which the running frequency cannot be too low, define the
low limit frequency running mode when the output frequency is lower than
[E0.10] 'Output frequency low limit'.
●
[E0.15] = 1: Run with low limit frequency
Fig. 12-16: Run with low limit frequency
A hysteresis band is set by E0.16. If actual setting frequency is higher than
[E0.10] + [E0.16] again, the output frequency will accelerate from [E0.10] to the
setting frequency according to the actual acceleration time.
If [E0.10] < [E0.16], [E0.16] will be set as [E0.10] automatically.
12.4.5 Frequency Setting Saving
With the 'Frequency setting saving' function, unexpected data loss of commis-
sioning or actual application engineering process can be avoided.

By default, the setting frequency configured by <▲> / <▼> or digital inputs will
not be saved either at power off or frequency converter stop during fine tun-
ing of the setting frequency in the actual application engineering process.
To avoid unexpected data loss of commissioning or actual application engi-
neering process, one of the following three options may be set according to
the actual application conditions:
●
1: Not saved when powered off; saved when stopped
●
2: Saved when powered off; not saved when stopped
●
3: Saved when powered off or stopped
●
4: Not saved when powered off; memorized when stopped
