signal is optional.
Features
Low Noise, Low Vibration Multi Axis 5-Phase Stepper Motor Driver
● Simultaneous operation of 2, 3-axis by single power supply
20-35VDC
● Small, light weight and advanced quality by custom IC and
surface mounted circuit
● Realizing low noise, low vibration rotation with microstep-driving
● Low speed rotation and high accuracy controlling
with microstep-driving
● Max. resolution - 250 division: In case of 5-phase stepper motor
of which basic step angle is 0.72°, it enables to control up to
0.00288° per pulse
● Includes auto current down and self-diagnosis function
● Photocoupler input insulation method to minimize the effects
from external noise

※
1: When using over 30VDC power supply, torque characteristics are improved but the driver temperature raise. The unit should be installed
at the well ventilation environment.
※
2: Based on ambient temperature 25
℃
, ambient humidity 55%RH.
※
3: RUN current varies depending on the input RUN frequency and max. RUN current at the moment varies also varies depending on the load.
※
4: Max. input pulse frequency is max. frequency to be input and is not same as max. pull-out frequency or max. slewing frequency.
※
5: The weight includes packaging. The weight in parenthesis is for unit only.
※
Environment resistance is rated at no freezing or condensation.
