SDBM8-050-05
Features And Benefits
SDBM8-050-05 is a micro-stepping drive designed for smooth and quiet operation without
compromising on torque and control at higher speeds. It has short-circuit protection for the motor
outputs, over-voltage and under-voltage protection and will survive accidental motor disconnects
while powered-up.
The SDBM8-050-05 achieves micro-stepping using a synchronous PWM output drive and high
precision current feedback and this is absolutely silent when the motor is stopped or turning slowly. It
virtually eliminates stopped-motor heating regardless of power supply voltage.
- Smooth and quiet operation at all speeds and extremely low motor heating
- Industrial grade performance for 2-Phase Bipolar and Uni-polar Stepper Motors
- Input supply voltage from 12VDc to 50VDC
- Selectable peak coil current from 0.5A to 5A
- Selectable half-current during motor standstill to further reduce motor heating
- Selectable micro-steps up to 8000 steps per rotation for a 1.8deg stepper motor
- Higher motor torque and higher speeds achievable due to advanced loop control algorithm
- PULSE, DIRECTION and ENABLE inputs with opto-isolated interface
- Short-circuit protection for the motor outputs, over-voltage and under-voltage protection
- LED indication for power and error states
