STM Series Drives
|
|
The STM Series is an integrated stepper drive+motor unit, fusing step motor and drive technologies into a single device, offering savings on space, wiring, and cost over conventional motor and drive solutions. The STM also fits with the ST product family of step motors and drives for a complete motion control system.

POWER SUPPLY |
External 12 - 70 VDC? Power Supply Required |
INPUT VOLTAGE RANGE |
12 - 70 VDC |
PROTECTION |
Over-Voltage, Under-voltage, Over-Temp, Motor/wiring shorts (Phase-to-Phase, Phase-to-Ground) |
IDLE CURRENT REDUCTION |
Reduction range of 0 – 90% of Running Current after delay selectable in milliseconds |
AMBIENT TEMPERATURE |
0 to 40°C (32 - 104°F) (mounted to suitable heatsink) |
HUMIDITY |
90% non-condensing |
MICROSTEP RESOLUTION |
Software selectable from 200 to 51200 steps/rev in increments of 2 steps/rev |
ANTI-RESONANCE
(Electronic Damping) |
Raises the system damping ratio to eliminate midrange instability and allow stable operation throughout the speed range 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) |
