CONTROLLER: All Models
MICROSTEP RESOLUTION Software selectable from 200 to 51,200 steps/rev in increments of 2 steps/rev.
ANTI-RESONANCE (Electronic Raises the system damping ratio to eliminate midrange instability and allow stable operation throughout the speed range Damping) and improves settling time.
TORQUE RIPPLE SMOOTHING Allows for fine adjustment of phase current waveform harmonic content to reduce low-speed torque ripple in the range 0.25 to 1.5 rps.
AUTO SETUP Measures motor parameters and configures motor current control and anti-resonance gain settings.
SELF TEST Checks Internal & External Power supply voltages. Diagnoses open motor phases and motor resistance changes >40%.
Detects encoder wiring and signal faults (differential encoder only).
MICROSTEP EMULATION Performs high resolution stepping by synthesizing fine microsteps from coarse steps (Step & Direction Mode Only).
COMMAND SIGNAL SMOOTHING Software configurable filtering reduces jerk and excitation of extraneous system resonances (Step & Direction Mode Only).
