| Description |
SEA2M44 is a microstep motor driver with uniform angle and constant torque subdivisions, voltage range is DC12~40V ( the optimal voltage is DC36V), single power supply. It matches 2 phase hybrid stepper motors which rated current under 4.5A, external diameter under 85mm, 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.

| Mark | Function | Instruction |
| POWER | Power Indicator | Power on, the green indicator normally on. |
| O.H | Fault Indicator | Overcurrent , phase open circuit, over voltage, low voltage, the red indicator flashes. |
| PU+ | Input signal positive side | Connects +3.3V～+28V pulse signal power. |
| PU- | Motor pulse signal | When the falling edge is valid, the motor moves a step as the pulse become lower, input resistance is 220Ω. Requires: low level +0V～+0.5V, high level +4V～+5V, pulse width>2.5μs. |
| DR+ | Input signal positive side | Connects +3.3V～+28V pulse signal power. |
| DR- | Direction control signal | For changing the direction, input resistance is 220Ω. Requires: low level +0V～+0.5V, high level +4V～+5V, pulse width >2.5μs. |
| MF+ | Input signal positive side | Connects +3.3V～+28V pulse signal power. |
| MF- | Motor free signal | When the low electrical level is valid, it cut off the motor current, the driver stops working and motor will be in a free state. |

| Alarm Function |
● 1 Green 1 Red Alternately flashes, Overcurrent;
● 1 Green 2 Red Alternately flashes, Phase open circuit;
● 1 Green 3 Red Alternately flashes, Overvoltage;
● 1 Green 4 Red Alternately flashes, Low voltage;
● 1 Green 5 Red Alternately flashes, Other faults;
The driver will loe self-locking function when the above alarms start, please clear faults and re-up electricity, the driver goes back to normal when the green power indicator normally on.
▲ Attention: the driver canot be protective when connects the wire inversely or wrongly, please confirm the connections before electrify it, otherwise the fuse inside may be burnout.
