Technical Specifications
POWER AMPLIFIER
AMPLIFIER TYPE Dual H-Bridge, 4 Quadrant
CURRENT CONTROL 4 state PWM at 20 Khz
OUTPUT TORQUE STM23x-2xx: 125 oz-in with suitable power supply
STM23x-3xx: 210 oz-in with suitable power supply
POWER SUPPLY External 12 - 70 VDC power supply required
PROTECTION Over-voltage (shutdown at 74VDC), under-voltage (shutdown at 11VDC),
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 mil-
liseconds.
OPERATING TEMPERATURE 0 to 85ºC (32 to 185ºF) Internal temperature of the electronics section and
encoder
0 to 100ºC (32 to 212ºF) Temperature of motor body
AMBIENT TEMPERATURE 0 to 40°C (32 - 104°F) (mounted to suitable heatsink)
HUMIDITY 90% max, non-condensing
AGENCY APPROVALS RoHS, CE EN61800-3:2004
CONTROLLER
MICROSTEP RESOLUTION Software selectable from 200 to 51200 steps/rev in increments of 2 steps/
rev.
MICROSTEP EMULATION Performs high resolution stepping by synthesizing fine microsteps from
coarse steps (step & direction mode only)
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%.
COMMAND SIGNAL SMOOTH-
ING
Software configurable filtering reduces jerk and excitation of extraneous
system resonances (step & direction mode only).
