FMDT220A48NOM is a new generation digital stepper motor driver based on the combination of DSP control and inverter technology. Suitable for various models of three-phase hybrid stepper motors with current below 4.8A and flange size between 60-110mm. The driver adopts a servo control principle similar to the circuit inside. This circuit can ensure smooth operation of the motor with almost no vibration or noise. Moreover, when the motor is running at high speed, the torque is much higher than that of traditional two-phase and five phase hybrid stepper motors, and the positioning accuracy can reach up to 60000 steps per revolution.

• The maximum response frequency can reach 200KPPS.
• 2. Optoelectronic isolation signal input/output.
• 3. The current setting is convenient, with a maximum driving current of 4.8A/phase.
• 4.16 constant moment subdivision at equal angles, with a maximum resolution of 60000 pulses per revolution.
• 5. Automatic half current regulation, when the step pulse stops for more than 1.5 seconds, the coil current automatically decreases to half of the set current.
• 6. Phase memory function (note: After the input stops for more than 3 seconds, the driver automatically remembers the motor phase at that time. When powered on again or when the MF signal changes from low level to high level, the driver automatically restores the motor phase).
• 7. Single power input, voltage range: AC110V-220V。
• 8. Passed CE TUV ISO certification.
