) Note!
l Only change between the operating modes if the controller is inhibited!
l Do not use the operating mode "Torque control" for applications with power
control!
l 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".
