disconnection
Idle Current
Reduction
Reduction range of 0 - 90% of running current after a delay selectable in milliseconds
Controller
Anti-Resonance
Raises the system-damping ratio to eliminate midrange instability and allow stable operation
throughout the speed range of the motor
Torque Ripple
Smoothing
Allows for fine adjustment of phase current waveform harmonic content to reduce low-speed
torque ripple in the range of 0.25 to 1.5 rps
Auto Test & Auto
Setup
Auto test and setup at power on (ie. motor resistance, and capacitance) to optimize your system
performance.
