Feature: 1. Efficient Working: This driver adopts the latest 32 bit DSP control technology enables the motor to achieve the best output performance. 2. Low Noise: This driver can automatically calculate the resonance point, effectively suppress the noise and vibration of the motor at low speed, and the precise current control makes the motor temperature rise low. 3. Wide Compatibility: This driver has a wide compatibility that the rotating speed of the driver can up to 1500rpm. 4. Fault Status Indication: This driver features under voltage, over voltage, over current, short circuit, open circuit, phase fault status indication and automatic protection function. 5. Wide Application: This driver is widely used in automatic equipment and instruments in various motion control fields, such as electronic processing and detection, semiconductor packaging, etc. Specification: Item Type: Stepper Motor Driver Mode: X86 Material: PC Voltage: DC24-80V, AC20-70V Rotating Speed: 1500rpm at most Driving Current: 2.4-7.8A, 8 gear adjustable Drive Subdivision: Resolution 400 to 51200 steps/rotation, 16 gear adjustable Maximum Pulse Frequency: 200Kpps Applicable Motor: for NEMA 56, 60, 86, Approx. 110mm / 4.33in stepping motor Application Field: Suitable for automatic equipment and instruments in various motion control fields, such as electronic processing and detection, semiconductor packaging, laser cutting and welding, laser phototypesetting, packaging machinery, engraving machines, marking machines, cutting machines, clothing plotters, CNC machine tools, automatic assembly equipment, etc. It is the first choice in the field where users expect low noise, superior high speed performance and strong cost performance.. Package List: 1 x Stepper Motor Driver Note: 1. The input voltage shall not exceed DC80V and AC70V. The green indicator PWR lights up when the drive is powered on.2. The driver fault indicator is on, please check the motor wiring and control signal line. In case of motor wiring and other short circuit faults, power on again for recovery after troubleshooting.3. Set the locking current function with SW4: ON: Full Current, OFF: Half Current.SW4 is set to OFF when leaving the factory, which reduces the heating of motor and driver and improves the reliability. The current automatically decreases by 50% 100ms after the pulse train stops.4. The driver has the function of single and double pulse selection, which can be set through the communication port. The factory default is pulse and direction.
