Operating Mode 2 0 Linear characteristic with
Auto-Boost
• Linear characteristic: for standard
applications
• Square-law characteristic: for fans and
pumps with square-law load characteristic
• Auto boost: load-dependent output voltage
for low-loss operation

4 Vector speed control • Vector speed control: for single-motor
applications requiring higher starting
torque and better speed regulation
5 Vector torque control • Vector torque control: for single-motor
applications requiring torque control
independent of speed
6 Enhanced linear characteristic
with Auto-Boost • Enhanced: for single or multiple
motor applications that require better
performance than settings 0...3, but
cannot operate in vector mode
7 Enhanced linear characteristic with
constant V

Note
• Settings 4...7 require Motor Calibration using c48
• Settings 4 and 5 require proper setting of C86...C91 prior to calibration
• Settings 6 and 7 require proper setting of C88...C90 prior to calibration

C16 not active in Vector mode (see C14)
Set after commissioning: The unloaded
motor should run at slip frequency (approx.
5 Hz), increase C16 until motor current
(C54) = 0.8 x rated motor current
