Function D Under C014 you can set the control mode and the voltage characteristic.
D The V/f-characteristic control with auto boost enables a low-loss operation of single
drives with standard three-phase AC motors with load-dependent V
min
boost.
D The motor-current control enables a ”Sensorless Speed Control”.Compared with the
V/f characteristic control, the drive can operate with a considerable higher torque
and consumes less current during idle running.
C014 = -2-

Square-law characteristic (e. g. for pumps,
fans)
