V/f characteristic control for asynchronous motor (VFC open loop)
The V/f characteristic control is a motor control for conventional frequency inverter applications. It is based on a simple and robust control mode for the operation of
asynchronous motors with a linear or square-law load torque characteristic (e.g. fan). Because of the minimal parameterisation effort,
such applications can be commissioned easily and quickly.
Preconditions
–
The V/f characteristic control is only suitable for asynchronous motors.
–
If you want to actuate a drive with a square-law V/f characteristic: Please always check whether the corresponding application is suitable for operation with a
square-law V/f characteristic!
square-law V/f characteristic!
–
Set the motor data according to the information on the nameplate of the motor.
