Feature: High efficiency: the latest 32-bit DSP control technology to achieve the best output performance of the motor. Low noise: Automatic calculation of resonance point, effectively suppressing noise and vibration of the motor at low speed. Long life: precision current control makes the motor temperature rise low. Large speed range: optional stepper motor, up to 1500rpm Interference frequency filtering: photoelectric isolation differential signal input, impulse response frequency up to 250Kpps Industrial grade components, mature and stable technology; undervoltage, overvoltage, overcurrent, short circuit, open circuit, tracking error, and other fault diagnosis status indication and automatic protection function The drive is suitable for the outer diameter 20~56mm series stepper motor. Suitable for a variety of automation equipment and instruments in the field of motion control, such as: electronic equipment, semiconductor equipment, laser cutting and welding, packaging machinery, engraving machines, CNC machine tools, automated assembly equipment. Specification: Model: FYDM403T Voltage: DC 24~40 V Drive current: 1.0~3.5A/phase 8 level adjustable Subdivision: The highest resolution is 25600 steps/rev. 16 level adjustable Maximum pulse frequency: 250 Kpps Package list: 1 * Motor Controller Note: 1. Do not reverse the power supply. Do not exceed the input voltage of DC40V. The green indicator light PWR lights when the drive is powered. 2. The input control signal voltage is 5V. When it is higher than 5V, the current limiting resistor needs to be connected. When the control signal voltage is 24V, a 2.2K 1/4W resistor should be connected in series. 3. The drive fault indicator is on. Please check the motor wiring and control signal line. If the motor is connected and other short-circuit faults, it needs to be restored after power-on. 4. SW4 to set the lock current function: ON=Full Current, OFF=Half Current. When SW4 is set to OFF at the factory, the heat generation of the motor and the driver is reduced, and the reliability is improved. The current is automatically reduced by 50% at approximately 100 ms after the pulse train is stopped. 5. The driver has a single and double pulse selection function, which can be selected by the internal shorting bar. The factory default is pulse + direction. 1、High efficiency: the latest 32-bit DSP control technology to achieve the best output performance of the motor. 2、Low noise: Automatic calculation of resonance point, effectively suppressing noise and vibration of the motor at low speed. 3、Long life: precision current control makes the motor temperature rise low. 4、Large speed range: optional stepper motor, up to 1500rpm 5、Interference frequency filtering: photoelectric isolation differential signal input, impulse response frequency up to 250Kpps
