Setting 3
Combination setting
(1) Set Pr.00.02 = 8 to lock
the keypad first
(2) Long press the ENTER
key for 5 seconds, set
Pr.00.02 = 8 to unlock the
keypad and then set
password in Pr.00.09. After
the password is set, check
Pr.00.02 displayed as 00
(indicating that the
parameter is encrypted).
(3) Reboot the drive to finish
the combination setting. If
you only finish the setting
of Step 2, the keypad is
still not locked even though
you cannot check
parameters through the
keypad.
(1) Check other parameter values that
are displayed as 0.00 (according to
the original decimal places of the
parameters), which protects the
customer's parameters.
(2) You cannot change all parameters,
including frequency command (F)
and PID target value.
(1) If you need to
change the process
controlling
parameters such as
frequency command
(F) or PID target
value, long press the
ENTER key for 5
seconds to modify
these parameters.
But other parameters
are still displayed as
0.00 (according to
the original decimal
places of the
parameter) and
cannot be modified.
(2) To change other
parameters except
the above mentioned
in point 1, set
Pr.00.08 again.

Control Method
Default: 0
Settings
0: V/F voltage frequency control
1: Vector control
 Determines the control mode of the AC motor drive.
 V/F voltage/ frequency control:
The V/F control is a constant value control mode. It stops the main problem of frequency
decreasing and magnetic field increasing. However, the magnetic field is not constant, an
insufficiency of motor’s torque in a weaken low frequency magnetic field may happen as the
frequency decreases. Set Pr.07.02 (Torque Compensation) properly to compensate the torque
for the best operating performance.
Applications: water pumps, conveyors, compressors and treadmills.
 Vector control:
Eliminate the related effect between the filed current vector and the armature flux. It auto-tunes
the torque compensation and slip compensation to increase the dynamic response of the motor
drive.
Applications: textile equipment, printing equipment, crane equipment and drilling machinery.
Related parameters: Pr.07.02 Torque Compensation
