power, Output torque, DC bus voltage, PID setpoint, PID feedback, Input terminal status, Output
terminal status, AVI value, ACI value, current segment of multi-speed, setting torque, the
function code F3.05 can decide these parameters wether to display by bit. Pressing the key
SHIFT can switch the display of the selected parameters regularly.
If the inverter is powered on again after power-off, the parameters displayed are defaulted as
those selected before the power-off.
4.4 Password Setting
ACD320 inverter provides password protection for users. When F3.00 is not zero, that is
the user password, once exiting the function code editing status, the password protection function
is valid if there is no operation within one minute. If the userpresses PRG/ESC again, the inverter
shall display “0.0.0.0.0.”, 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.
4.5 Auto Tuning of Motor Parameters(Referto F1.11)
Before running the inverter that has selected the vector control mode or open loop torque mode,
accurate motor nameplate parameters must be input to the inverter correctly. ACD320 inverter
will configure the standard motor parameters according to the nameplate parameters. Vector
control mode is highly dependent on the motor parameters and correct parameters must be
acquired for achieving good control performance.
Motor auto tuning procedures:
Firstly set the command 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 frequency 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 1 (complete tuning) in F1.11, and
press RUN in keypad, the inverter will calculate the parameters below automatically:
F1.06 Stator resistance
F1.07 Rotor resistance
F1.08 Leakage inductance
F1.09 Mutual inductance
F1.10 Excitation current with no load
