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.
Non-Volatile Storage
Configurations are saved in FLASH memory on-board the DSP
