3phase NEMA42 NEMA52 hybrid stepper motor driver DSP AC110V-220V 7A LC3722A

Product Name: three-phase 110/130 digital stepping driver LC3722ALC3722A is a three-phase hybrid stepping motor driver based on DSP control. It is a new generation of digital step motor driver which combines advanced DSP control chip and three-phase inverter driver module. The drive voltage is AC110V~220V, the adaptation current is below 7.0A, and the outer diameter of 57-130MM is various types of three-phase hybrid stepping motors. The drive circuit adopts similar internal servo control principle, this circuit can make the motor running smooth, almost no vibration and noise, the motor at high speed when the torque is much higher than the two-phase and five phase hybrid stepping motor. The positioning accuracy can be up to 60000 steps / rev. The product is widely used in engraving machines, medium-sized CNC machines, computer embroidery machines, packaging machinery and other high resolution, large and medium-sized CNC equipment. Product features:High performance and low pricewith 16 levels, equal angle constant moment subdivision, the highest resolution of 60000 p/rThe highest response frequency is up to 200KPPSWhen the step pulse stops more than 1.5S, the coil current is automatically reduced to half of the set currentopto isolated signal input / outputDrive current 1.3A/ phase to 7.0A/ phase, 16 levels adjustableSingle power input, voltage range: AC110V-220Vphase memory function (Note: after the input is stopped for more than 3 seconds, the driver automatically memories the motor phase at that time, re power or the WF signal changes from low to high, and the driver automatically restores the motor phase Interface definition connector pin Symbol function instruction DB 15 1 5PU+ Input signal photoelectric isolation positive Connect +5V power supply, +5V-24V can drive, higher than +5V, need to meet current limiting resistor 2 PU- DP9=OFF，PU is a step pulse signal The falling edge is valid. When the pulse is changed from high to low, the motor takes one step and the input resistance is 220. It requires: low level 0-0.5V, high level 4-5V, pulse width > 2.5 us DP9=ON，PU is a positive step pulse signal 3 5DR+ Input signal photoelectric isolation positive end Connect +5V power supply, +5V-+24V can drive, higher than +5V, need to meet current limiting resistor 4 DR- DP9=OFF，DR is the directional control signal Used to change motor steering. Input resistance 220 Ohm, required: low level 0-0.5V, high level 4-5V, pulse width＞2.5μs DP9=ON，DR is a backward stepping pulse signal 7 5MF+ Input signal photoelectric isolation positive end Connect +5V power supply, +5V-+24V can drive, higher than +5V, need to meet current limiting resistor 8 MF- Motor release signal The current of the motor is switched off when the active (low level) is switched off, the motor is stopped and the motor is in free state 9 ALM+ Drive fault output signal photoelectric isolation positive end Drive overcurrent, overheating fault, actuator fault signal, the signal active 10 ALM- Drive fault, output signal, photoelectric isolation, negative end 11 RDY+ The drive is ready to output the photoelectric isolation terminal The drive is in normal condition and ready to accept the controller signal when the signal is valid 12 RDY- The driver ready to the output signal to isolate the negative terminal 13 24PU+ Input signal photoelectric isolation positive end +24V 14 24DR+ Input signal photoelectric isolation positive end +24V 15 24MF+ Input signal photoelectric isolation positive end +24V Motor power connector 1、2 L、N power power：AC110-220V 3 PE GND The earth 4 U Motor connection 5 V 6 W Application:Suitable for all kinds of motion control automation equipment and instruments, such as electronic processing and testing, semiconductor packaging, laser cutting and welding, laser printing, packaging machinery, engraving machine, marking machine, cutting machine, apparel plotter, CNC machine tools, automatic assembly equipment etc.. It is the first choice for users with low noise, high speed performance and competitive cost performance.
