ProductName: three-phase 110/130 digital stepping driver LC3722A
LC3722A is a three-phase hybrid steppingmotor driver based on DSP control. It is a new generation of digital step motordriver which combines advanced DSP control chip and three-phase inverter drivermodule. 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 hybridstepping motors. The drive circuit adopts similar internal servo controlprinciple, this circuit can make the motor running smooth, almost no vibrationand noise, the motor at high speed when the torque is much higher than thetwo-phase and five phase hybrid stepping motor. The positioning accuracy can beup to 60000 steps / rev. The product is widely used in engraving machines,medium-sized CNC machines, computer embroidery machines, packaging machineryand other high resolution, large and medium-sized CNC equipment.
Productfeatures:
Highperformance and low price
with16 levels, equal angle constant moment subdivision, the highest resolution of60000 p/r
Thehighest response frequency is up to 200KPPS
Whenthe step pulse stops more than 1.5S, the coil current is automatically reducedto half of the set current
optoisolated signal input / output
Drivecurrent 1.3A/ phase to 7.0A/ phase, 16 levels adjustable
Singlepower input, voltage range: AC110V-220V
phasememory function (Note: after the input is stopped for more than 3 seconds, thedriver automatically memories the motor phase at that time, re power or the WFsignal changes from low to high, and the driver automatically restores themotor phase
Interface definition
Connect +5V power supply, +5V-24V candrive, higher than +5V, need to meet current limiting resistor
The falling edge is valid. When the pulseis changed from high to low, the motor takes one step and the inputresistance is 220. It requires: low level 0-0.5V, high level 4-5V, pulsewidth 2.5 us
Connect +5V power supply, +5V-+24V candrive, higher than +5V, need to meet current limiting resistor
Used to change motor steering. Inputresistance 220 Ohm, required: low level 0-0.5V, high level 4-5V, pulse width
