Description

       SEB2M55 Using 32bit DSP control technology, the max rotate speed up to 3000rpm, the attenuation of high speed torque is much lower than that of the common open-loop stepper motor, it greatly improves the performance of the closed-loop stepper motor speed and torque utilization, effectively reduces the vibration and heat, so as to improve the processing officiency and precision of the equipment. Voltage DC24V~50V ( the optimal voltage is DC48V ), single power supply. It matches 2 phase hybrid closed-loop stepper motors which rated current under 5A, external diameter 20mm~60mm.

       Based on the load current control technology, it can effectively prolong the service life of the motor. Position arival signal and alarm signal has built into the driver to facilitate the monitoring and control of the controller.

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.

ALM+

Alarm signal output positive side

It flashes when ( Output optocoupler breakover ) Overcurrent, Phase open circuit Overvoltage, Low voltage, Position deviation alarm.

ALM+ connects to the positive pole, ALM- connects to the negative pole, max current 50mA.

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.
