Control Mode
Default: 0
Display 0 V/F Control
1 Vector Control
Determines the control method for the AC motor drive.
V/F Control: (Voltage/Frequency Control)
The V/F control is a constant value control mode. In this control mode, frequency decreasing and magnetic
field increasing are under control. But as the frequency decreases, a problem rises: the insufficiency of motor’s
torque in a weaken low frequency magnetic field. To solve this problem, set Pr.07.02 Torque Compensation to
compensate torque then to have the best operating performance. Common applications are water pumps,
conveyors, compressors and treadmills.
Vector Control:
The vector control mode can eliminate the relationship between the field current vector and the armature flux,
and auto-tune the torque compensation and slip compensation to increase the dynamic response of the motor
drive. Common applications are textile equipment, printing equipment, crane equipment and drilling machinery.
