Technical Specications

Power AmPlifier

Amplier Type Dual H-Bridge, 4 Quadrant

Current Control 4 state PWM at 16 KHz

Output Torque STM17x-1x Series – to 31 oz-in with suitable power supply

STM17x-2x Series – to 54 oz-in with suitable power supply

STM17x-3x Series – to 68 oz-in with suitable power supply

Power Supply External 12-48 volt power supply required

Input Voltage Range 10-55 volts min/max (nominal 12-48 volts), voltages outside this

range may cause driver faults and/or may damage the device

Protection Over-voltage, under-voltage, over-temp, internal motor shorts

(phase-to-phase, phase-to-ground)

Idle Current Reduction Reduction range of 0–90% of running current after a delay select-

able in milliseconds

Controller

Current Control Advanced digital current control provides excellent high speed

torque

Microstep Resolution Software selectable from 200 to 51200 steps/rev in increments of

2 steps/rev

Speed Range Speeds up to 80 rps

Distance Range Over 10,000,000 revolutions (at 200 steps/rev)

Anti Resonance (Electronic

Damping)

Raises the system-damping ratio to eliminate midrange instability

and allow stable operation throughout the speed range of the mo-

tor

Auto Setup Measures motor parameters and congures motor current control

and anti-resonance gain settings

Self Test Checks internal and external power supply voltages, diagnoses

open motor phases

Microstep Emulation Performs high resolution stepping by synthesizing coarse steps into

ne microsteps

Dynamic Smoothing Software congurable ltering for use in removing spectral compo-

nents from the command sequence, reduces jerk, limiting excita-

tion of system resonance

Dynamic Current Control Software congurable for running current, accel current, idle cur-

rent, to make motion smoother and the motor run cooler
