Description |
SEB2M25 is equipped with a 32-bit ARM Cortex-M4 core high-performance microcontroller, and with advanced manufacturing process, it can effectively improve the overall performance and the operation speed can reach 200MHz. Its max rotation is above 3000rpm, and its attenuation amplitude of holding torque at high speed is far under that of common open-loop stepper driver, which can greatly improve the high-speed performance and operation frequency of holding torque, and effectively reduce the motor vibration and heating so as to improve the manufacturing efficiency and precision. Stepper driver voltage is DC24V~50V(The optimal voltage is DC48V), which can match the single-phase hybrid closed-loop stepper motor with 28mm~42mm external diameter under 2.2A.
The stepper driver internally adopts current control technology according to the load, which can effectively extend the life of the closed-loop stepper motor and reduce the heat. The driver has position arrival signal and alarm signal output to monitor and control effectively.

Alarm functions |
● When 1 Green and 1 Red flashes, it means that the power supply voltage of the closed-loop driver is low; solution: check whether the power supply voltage of the closed-loop driver is too low;
● When 1 Green and 2 Red flashes, it means that the power supply voltage of the closed-loop driver is high; solution: check whether the power supply voltage of the closed-loop driver is too high;
● When 1 Green and 3 Red flashes, it means that the phase of the closed-loop stepping motor is open; the solution: check whether the wiring of the closed-loop stepping motor is wrong;
● When 1 Green and 4 Red flashes, it means that the closed-loop stepper motor phase is over-current; solution: check whether the closed-loop driver MOS tube is damaged or whether the closed-loop stepper motor is damaged;
● When 1 Green and 5 Red flashes, it means the closed-loop stepper motor encoder is faulty; solution: check whether the closed-loop stepper motor encoder is wired correctly and whether it is damaged;
● When 1 Green and 6 Red flashes, it means that the feedback position of the closed-loop stepping motor encoder is out of tolerance; solution: check whether the closed-loop stepping motor loses steps;
● When 1 Green and 7 Red flashes, it means the closed-loop driver has other faults; solution: send it back to the manufacturer for inspection;
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.
