       SEB2M55-R RS485 Modbus-RTU closed-loop stepper driver increses bus communication and single shaft control function on basis of closed-loop stepper driver.

       The bus closed-loop stepper driver can completely replace the closed-loop stepper driver with traditional pulse direction control function, and in-built driver bus communication function, which takes the Modbus-RTU bus communication so that the users can control 64 pieces of drivers at the same time. Besides, the updated closed-loop stepper driver has planty input / output connectors for accomplishing single-shaft control function like the position control, speed control, and returning function etc. Compared to traditional closed-loop stepper driver, this bus closed-loop stepper driver is suitable for the the machion needing many pieces of drivers, far distance and strong signal interference condition. Closed-loop stepper driver voltage is DC24V~50V(The optimal voltage is DC48V), which adops single-phase power suitable for single-phase closed loop stepper motor with 56mm~60mm external diameter under 5A.

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

● 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.
