Small, Light, High Speed & Torque 5-Phase Stepper Motor Driver
● Bipolar constant pentagon drive method
● Includes auto current down and self-diagnosis function
● Low speed rotation and high accuracy controlling with
microstep-driving (MD5-HD14, MD5-HF14, MD5-HF14-AO,
MD5-HF28)
[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 and it requires 125,000
pulses per rotation.]
● 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: In case of MD5-HF14-AO, MD5-ND14, there are no DIVISION SELECTION, ZERO OUT function.
※
5: Max. input pulse frequency is max. frequency to be input and is not same as max. pull-out frequency or max. slewing frequency.
※
6: The weight includes packaging. The weight in parenthesis is for unit only.
※
Environment resistance is rated at no freezing or condensation.
