The MDrive23Plus Speed Control is a NEMA size 23 high torque 1.8° stepping motor integrated with a microstepping driver and an intelligent velocity controller.
Features include:
- SPI communications
- +12 to +75 VDC input voltage
- Up to 283 oz-in (200 N-cm) holding torque
- 10-bit analog input which can operate in three different input modes: voltage, current and PWM.
- 20 microstep resolutions from full step to 51,200 steps per revolution.
- Programmable Run and Hold Current
- All parameters are software configuarable (setup utility included) - no external switches or resistors required.
