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

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

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
