       SEA3D64 is a microstep motor driver with uniform angle and constant torque subdivisions, voltage range is DC16～60V ( the optimal voltage is DC50V ), single power supply. It matches 3 phase hybrid stepper motors which rated current under 5.8A, external diameter 42mm～85mm, and outlets 3 or 6.

       Bipolar constant current chopper control makes the motor run smoothly with lower noise and higher stability, The increase of the voltage greatly improves the drive capability. and speed, The coil current will be halved automatically onece the pulse stops for more than 100ms, it reduces the heat of driver by 50%, reduces the heat of motor as well. Users can choose low speed high subdivision which up to 60000steps / rev, it improves the precision, reduces the vibration and noise.

1. Please do not reverse the power supply, input voltage not more than DC60V;

2. The input control signal level is +5V, if higher than +5V, needs to add a resistor on PU-, DR-, FM- ( do not add on + sides );

3. This model of the driver uses a special control circuit, so it matches stepper motor of 6 or 8 outlets only;

4. The driver will automatically stop working when the temperature exceeds 70 degrees, the O.H indicator light normally on, temperature drops to 50 degrees it automatic recovers to work, please install radiator when it's in overheating protection;

5. When the current exceeds rated value or the voltage is lower than rated value, the O.C indicator light normally on, please check the connections and other short troubles needs to re-up power after the faults cleared, or if the power voltage is too low;

6. The PWR green indicator light normally on when the driver is powered on;

7. The TM indicator light comes on when the pulse input go crossing the zero point.
