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

IMPORTANT
• 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: for single-motor
applications requiring higher starting
torque and better speed regulation
• Vector torque control: for single-motor
applications requiring torque control
independent of speed
• Enhanced: for single or multiple
motor applications that require better
performance than settings 0...3, but
cannot operate in vector mode

• As chopper frequency is increased, motor
noise is decreased
• Observe derating in Section 2.2
• Automatic derating to 4 kHz at 1.2 x Ir
40.0 Change C21 until the motor speed no longer
changes between no load and maximum
load
