0.00Hz
○
When the frequency upper limit for analog or PULSE setting, F0-13 as the offset of set value, the
offset frequency and F0-11 set frequency upper limit value superposition, as the final frequency upper
limit set value.
F0-14
Frequency Lower
Limit
0.00Hz~frequency upper limit F0-12
0.00Hz
○
When frequency instructions is lower than the frequency lower limit of F0-14 set, inverter can stop,
running at frequency lower limit or zero speed, what running mode can be through the F1-17 (set
frequency is lower than the frequency lower limit running mode) set.

●
The parameter used to determine all the resolution of the function code associated with the
frequency.
When frequency resolution is 0.01Hz, the maximum output frequency of VD520 is 600.00Hz.

◎
This parameter is only valid when frequency source for the digital setting.
Used to determine the keypad key
▲,▼ or terminal UP/DOWN action, adopt what way correction set
frequency, namely the target frequency is increase or decrease based on the running frequency, or
increase or decrease base on the set frequency.
The difference between two kinds of settings, evident when inverter in the deceleration process,
namely if the running frequency of inverter is different with the set frequency, the parameter different
selection difference is very big.

○
The function is only valid when frequency source for the digital setting.
“No memory” refers to the frequency inverter after downtime, digital set frequency values revert to
F0-09 (preset frequency) value, keypad key
▲,▼or terminal UP/DOWN to correct the frequency is
zero.
“Memory” refers to the frequency inverter after downtime, digital set frequency keep set frequency for
the last moment downtime, keypad key
▲,▼or terminal UP/DOWN to correct the frequency is remain
valid.

Acceleration time refers to the time required that frequency inverter from zero frequency acceleration
to acceleration/deceleration reference frequency (F0-21), as show in figure 6-1 in the t1.
