PROTECTION
IDLE CURRENT REDUCTION
Over-voltage, under-voltage, over-temp, motor/wiring shorts (phase-to-phase, phase-to-ground)
STM17S/Q/C:
Reduction range of 0 - 90% of running current after delay selectable in milliseconds.
STM17R:
Switch selectable 50% or 90% of running current.
CONTROLLER:
MICROSTEP RESOLUTION
STM17S/Q/C:
Software selectable from 200 to 51200 steps/rev in increments of 2 steps/rev.
STM17R:
Dip-switch selectable 200, 400, 800, 1000, 1600, 2000, 3200, 4000, 5000, 6400, 8000, 10000,
12800, 20000, 25000 or 25600 steps/rev.
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)
Raises the system damping ratio to eliminate midrange instability and allow stable operation throughout the speed
range and improves settling time
Measures motor parameters and configures motor current control and anti-resonance gain settings
Checks internal & external power supply voltages, diagnoses open motor phases
Configurations are saved in flash memory on-board the DSP
