Description

       SEA2M44 is a microstep motor driver with uniform angle and constant torque subdivisions, voltage range is DC12V~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 56mm~60mm, and 4, 6 or 8outlets.

       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 40000 steps / rev, it improves the precision, reduces the vibration and noise.

Function

Instruction

POWER

Power indicator

Power on, the green indicator normally on.

O.H

Fault indecator

Overcurrent, phase open circuit, overtension, low voltage, the red indicator flashes.

PU+

Input signal positive side

Connects +3.3V~+28V pulse signal power.

PU-

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 cuts off the motor current, the driver stops working and motor will be in a free state.

Alarm functions

●  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 lose self-locking function when the above alarms start,please clear faults and re-up electricity,the driver goes back to normal when the power green indicator normally on.

 

▲  Attention:The driver can't be protective when connects the wire inversely or wrong,please confirm the connections before electrify it,otherwise the fuse inside may be burnout.
