Selection of the correct operating mode

4.2 Selection of the correct operating mode
The control mode of the controller can be selected via the operating mode. You can select between
l
V/f characteristic control
l
Vector control
l
Sensorless torque control
Selection of the correct operating mode
V/f characteristic control is the classic operating mode for standard applications.
The vector control provides a better control performance than the V/f characteristic control due to:
l
a higher torque over the whole speed range
l
a higher speed accuracy and concentricity factor
l
a higher efficiency

Operating modes recommended for standard applications
The following table helps you to find the correct operating mode for standard applications:
Application
Single drives
With extremely alternating loads
With high starting duty
With speed control (speed feedback)
With high dynamic response (e. g. positioning and infeed drives)
With torque setpoint
With torque limitation (power control)
Three−phase AC reluctance motors
Three−phase sliding rotor motors
Three phase motors with assigned frequency−voltage characteristic
Pump and fan drives with square−law load characteristic
Group drives
(several motors connected to one controller)
Identical motors and identical loads
Different motors and/or changing loads
C0014 = 2: linear V/f characteristic control
C0014 = 3: square−law V/F characteristic control
C0014 = 4: vector control
C0014 = 5: sensorless torque control
