Selecti on of inverter frequency command i nput channels. There are 7 main frequency set ting channel s:
0: Keyboard
Ac complish keyboa rd frequency set ting by me ans of modifying t he value of function code F0.07
Keyboard freque ncy sett ing
.
1: VI
2: External terminal AI
This means that the freque ncy is set up through analog input terminals. DZB seri es invert er provides 2
analog input channel. AVI is 0-10V voltage input mode , whi le ACI i s 0 (4)-20mA input.
The 100.0% set ting of analog input is corresponding to the maxi mum frequency (Funct ion Code F 0.04),
and -100.0% i s corres ponding to maximum reverse fre quency (Function Code F0.04).
3:Reserved
4:Multi-s peed operation
The inverter is operated i n t he mode of mult i-speed onc e thi s frequency setting mode is chosen. It is
needed to s et up the parameters of F2 Group and F4 Group
Multi -speed control group
to determine the
coi ncidence relation bet ween given pe rcentage and given frequency.
5
PID control
Selecti on of this parameter means that the operation mode of inverter i s PID control mode.In this c as e,
it is required to set up F4 Group
PID control group
. The operati on frequency of i nverter is the frequency
val ue which PID gives. Please refer to the description of F4 Group
PID functi ons
for t he definition of
PID s etpoint source, assigned value, fee dback source and so on.

It is us ed to set up t he maximum out put frequency of inverter. P leas e note that, it is the ba sis of frequency
setting and acceleration/de cel eration speed.
It is the upper li mit of inverter output frequenc y, w hich should be less t han or equal to the maxi mum
output frequency.
The l ower l imit of inverter output frequency.
If setpoint frequency is lower than lower limit frequency whe n startup, inverter c an not run.operate at

Accel erati on t ime means the time t1 required for i nvert er to accelera te t o the ma ximum output
frequency (F0.04) from 0Hz.
D ecele rat ion ti me is the time t2 requi red for inverte r to decelerate to 0Hz from t he maximum out put
frequency (F0.04).
It is indi cated by following figure

0: Val id, and the inverter memorizes when power down. Able to set up frequency command, and memorize
thi s set frequency when the invert er is power down. When the power is back,automatically combine it with
current frequency sett ing.
1: Val id, and the inverter does not memori ze when power i s down. Able to set up frequency,but when the
inve rte r power is down, thi s frequency setti ng i s not memorized.
2: Invalid. The frequency set through keyboard and terminal UP/DOWN is autom atical ly cleared,and the
settings through keyboard and terminal UP/DOWN are i nvalid.
Note: After the user restor es t he defaul t val ue s of inverter function paramete rs, th e frequency
val ue, set through keyboard and termi nal UP/DOWN, is automat icall y cl eared.
