Recommended operating modes for standard applications
The following table helps you to select the appropriate mode of operation for standard
applications:
Application Operating mode
Single drives
Setting in C0014
recommended alternatively
With strongly alternating loads 4 2
With a high starting duty 4 2
With speed control (speed feedback) 2 4
With a high dynamic performance (e.g. positioning and infeed drives) 2 −
With a torque setpoint 5 −
With torque limitation (power control) 2 4
Three−phase reluctance motors 2 −
Three−phase sliding rotor motors 2 −
Three−phase AC motors with a fixedly assigned frequency−voltage
characteristic 2 −
Pump and fan drives with a square−law load characteristic 3 2 or 4
Group drives
(several motors connected to one controller)
Equal motors and equal loads 2 −
Different motors and/or alternating loads 2 −
C0014 = 2: linear V/f characteristic control
C0014 = 3: square−law V/f characteristic control
C0014 = 4: vector control
C0014 = 5: sensorless torque control
)
Note!
ƒ Only change between the operating modes if the controller is inhibited!
ƒ Do not use the operating mode "Torque control" for applications with
power control!
ƒ Optimum drive behaviour in process controller applications, e.g. with speed
control or dancer position control can be achieved with the control modes
"linear V/f characteristic control" or with "vector control".
– If you need a high torque at low speed we recommend the operating mode
vector control".
