Technical Specications

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 aer 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 Soware selectable from 200 to 51200 steps/rev in increments of 2 steps/

rev.

MICROSTEP EMULATION Performs high resolution stepping by synthesizing ne 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 seling time.

TORQUE RIPPLE SMOOTHING Allows for ne 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 congures motor current control and anti-

resonance gain seings

SELF TEST Checks internal & external power supply voltages. Diagnoses open motor

phases and motor resistance changes >40%.

COMMAND SIGNAL SMOOTH-

ING

Soware congurable ltering reduces jerk and excitation of extraneous

system resonances (step & direction mode only).
