VD120 Series Inverter User Manual Parameter Description
-
69
-
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 VD120 is 600.00Hz.
F0-16
Frequency Command
UP/DOWN
Reference in Running
0: Running frequency
1: Set frequency
0
◎
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.
Deceleration time refers to the time required that frequency inverter from deceleration/deceleration
reference frequency (F0-21) deceleration to zero frequency, as show in figure 6-1 in the t2.

VD120 provide 4 groups acceleration/deceleration time, user can use digital input terminal DI switch
selection, 4 groups of acceleration/deceleration time through following function code to set:
The first group: F0-18, F0-19; The second group: Fb-03, Fb-04;
The third group: Fb-05, Fb-06; The forth group: Fb-07, Fb-08;
