External 12 - 70 VDC Power Supply Required
12 - 70 VDC
Over-Voltage, Under-voltage, Over-Temp, Motor/wiring shorts (Phase-to-Phase, Phase-to-Ground)
Reduction range of 0 – 90% of Running Current after delay selectable in milliseconds
0 to 40°C (32 - 104°F) (mounted to suitable heatsink)
90% non-condensing
-20
Software selectable from 200 to 51200 steps/rev in increments of 2 steps/rev
Raises the system damping ratio to eliminate midrange instability and allow stable operation throughout the speed
range and improves settling time
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
Measures motor parameters and configures motor current control and anti-resonance gain settings
Checks Internal & External Power supply voltages. Diagnoses open motor phases and motor resistance changes
>40%. Detects encoder wiring and signal faults (differential encoder only)
Performs high resolution stepping by synthesizing fine microsteps from coarse steps (Step & Direction Mode Only)
Software configurable filtering reduces jerk and excitation of extraneous system resonances (Step & Direction
Mode Only)
Configurations are saved in FLASH memory on-board the DSP
