●  High performance, low noise, affordable price, high speed and torque, excellent stability

●  16 selections of uniform angle and constant torque subdivisions, the max resolution up to 40000 steps/rev

●  Adoption of 4-wires-control circuit greatly reduces noise and increases the rotation stability

●  The max response frequency up to 200KHz

●  Once the pulse stops for more than 100ms, the coil current will be halved automatically, to prevent the overheating

●  Once the pulse stops for more than 100ms, the coil current will be reduced to 20%～80% ( set by STOP ) automatically

●  Bipolar constant current chopper control improves the output speed and power of the motor

●  Optically isolated signal I / O

●  Current range:0.5A～8.0A / be devided into 16 grades

●  Single power input, voltage: AC60-130V ( The optimal voltage is AC110V )

●  Error protection: ① Overheating ② Overcurrent ③ Low voltage

●  Size: 200×156×80（mm）, Net weight: 2.3kg

       SEA2D810 is a microstep motor driver with uniform angle and constant torque subdivisions, Stepper driver voltage is AC60V～130V ( The optimal voltage is AC110V ), single power supply. It matches 2 phase hybrid stepper motors which rated current under 8.0A, external diameter under 86mm~130mm, and 4 or 8 outlets.

       Bipolar constant current chopper control makes the motor run smoothly with lower noise and higher stability; the increse of the voltage greatly improves the driver capability and speed. The coil current will be halved automatically once 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 is up to 40000 steps / rev, it improves the precision , and reduces the vibration and noise.

1． STOP/Im sets the potentiometer for holding output current stable, and can be set to 20%~80% of the normal output current (clockwise increase, counterclockwise decrease).

2．RUN/Im is the normal working output current setting switch (see table below for details).

1. Please do not reverse the power supply, input voltage not more than AC130V;

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.
