Password Setting
DZB300 inverter provides password protection for users. When F3.00 is not zero, that is the user password,
and the password protection function is valid once exiting the function code editing status. If the user
"
presses PRG again, the inverter shall display
------ , and the user can only enter the menu after
inputting the user password. Otherwise, the user cannot enter.
If the user wants to cancel the password protection function, F3.00 should be set 0.

Auto Tuning of Motor Parameters
(Refe r to F1.11)
：
Note This function is invalid for DZB200 Series.
Before running the inverter that has sele cted the vector control mode, accurate motor nameplate
parameters must be input to the inverter correctly. DZB300 inverter will configure the standard motor
paramet ers according to the nameplate parameters. Vector control mode is highly dependent on the
motor pa rameters and corre ct parameters must be acquired for achieving good control performance.
Motor auto tuning procedures:
Firstly set the comma nd source (F0.01) as the operation panel command channel.
Then input the following parameters according to the actual parameters of motor:
：
；
F1.01 Rated power of motor
：
；
F1.02 Rated freque ncy of motor
：
；
F1.03 Rated speed of motor
：
；
F1.04 Rated voltage of motor
：
。
F1.05 Rated current of motor
If the motor is disconnected from the load completely, select
press RU N in keypad, the inverter will calculate the parameters below automatically:
：
；
F1.06 Stator resistance
：
；
F1.07 Rotor inducta nce
：
；
F1.08 Leakage inductance
：
；
F1.09 Mutual inductance
：
；
F1.10 Excitation current with no load
Motor tuning is finished automatically.
If the motor cannot disconnect from its load, set F1-11 to
The inverter will measure the stator resistance, rotor resistance and leakage inductance in sequence, but
it will not calculate the mutual inductance and the excitation current with no load, and the user can use
the nameplate parameters that are rated voltage U, rated current I, rated frequency f and power factor
η
to calc ulate these two pa rameters:
The calc ulation methods of the motor current with no load and the mutual inductance are described as
follows.

Chapter 5 Function parameters list
DZB300series inverter function parameters, which are grouped by functions, have F0-F6 total 7 groups.
Each function group includes a number of function codes, which adopts three-stage me nu, for instance,
"
"
F4.08
means the 8th function code of F4th function.
For the convenience of setting function code by using operation panel, the function group number is
corresponding to Stage 1 menu, the function code is corresponding to Stage 2 menu and the function code
parameter is corresponding to Stage 3 menu.
1. The column of function table is described as follows:
"
"
The 1st column
Function Code
is the function parameter group and parameter code.
"
"
The 2nd column
Name
is the complete name of the function pa rameter.
"
"
The 3rd column
Setting Range
is the effective setting value ra nge of the function parameter,
shown on the opera tion panel LCD.
"
"
The 4th
Default
is the original factory setting value of this function parameter.
"
"
The 5th
Modification
is the modification perf ormance of the function paramete r (i.e. whether
or not it is permitted to modify and t he modification c onditions), explained as follows,
"※"
: indicat es that the setting value of this parameter can be modified when the inverter is
either in stop or ope rating status;
"●"
: means that the setting value of this parameter cannot be modified when the inverter is in
operating status;
" "
**
: means that this parameter is a test value which cannot be modified.
(Inverter has done the automatic detection restriction to the modification performance of each parameter,
helping user to prevent mis-modific ation.)
"
"
The 6th column
Serial No
is the number of function code at the storage inside.
"
"
2. Default
indicates the value of the function c ode after it is refreshed while doing the manipulation of
restoring the factory parameters; but the actually dete cted parameters or record values cannot be refreshed.
3.In order to effe ctively protect the parameters, the inverter provides the cryptoguard for the function code.
'
'
Af ter the user s password is set up (i.e. user s password F3.00 parameter is not 0), when the user press PRG
button to enter function code edit status, the system first enters the user s password ve rification status,
"
"
displaying
----- , and the operator must input correctly the user s password, otherwise it is impossible to
enter. At the state that the cryptogua rd is not locked, the user s password can be modified at any time, and the
'
one finally input will be the user s password. If F3.00 is set as 0, the user s password can be cancelled; when
the power is on, if F3.00 is not 0, parameters are protected by password.
4. When modify parameter using serial communic ation, usage of user password also abide above principle.
