DM432ES  is a digital stepper motor driver launched by Dongfang Servo CNC Technology Co., Ltd., using the latest 32-bit DSP technology, the user can set any subdivision in 256 and any current value in the rated current. Due to the use of low-speed/medium-speed anti-resonance technology, the built-in micro-division technology, even in low subdivision conditions, can achieve a high subdivision of the effect, low and high speed operation are very smooth, the noise is super small. The drive interior integrates the parameter automatic tuning function, can automatically generate the optimal operation parameter for different motor, maximizes the performance of the motor.


  Through PC software or handheld programmer debugger, set pulse rise or drop trigger is effective, you can also set a single pulse mode or dual pulse mode.


application area

  Combined with a variety of sports control field automation equipment and instruments, such as: electronic processing and testing, semiconductor packaging, laser cutting and welding, laser imagesetter, packaging machinery, engraving machine marking machine, cutting machine, garment plotter, CNC machine tools, automated assembly equipment. Is that the user expects low noise.  High performance and superior price than competitive areas of the preferred choice!


Driver Function Operation Instructions



1) Micro-step Group score settings: By SW5-SW8 four digital switches to set the drive micro-step subdivision teaching, which has a total of 15 micro-step subdivision. When the user sets a micro-step subdivision, the drive should be stopped to run first.


For specific micro-step subdivision settings, please see the drive surface layout description. 2) Output current setting: By SW1-SW3 three connector switch to set the drive output current, its output current has a total of 8 gears.


For the setting of the specific output current, see the drive surface description. 3) Automatic half-flow function: The user can set the automatic half-stream function of the drive through the SW4.  Off indicates that the static power is set to half of the dynamic current, and on indicates that the static current is the same as the dynamic current. SW4 should be set to off in general use, resulting in reduced energy consumption and increased reliability of motors and drives.


After the pulse string stops about 0.4s, the current is automatically reduced to about half (60% of the actual value), and the heat is theoretically reduced by 36%.


4) Signal Interface:


Pul+ and pul-are the positive and negative ends of the control pulse signal: dir+ and dir-are the positive and negative ends of the directional signal: ena+ and ena-are the positive and negative ends of the enabling signal.


5) Motor Interface:


A+ and a-are connected to the positive and negative ends of the motor A-phase winding: the positive and negative end of the B-phase winding of the b+ and b-Stepper motor: In any one phase of a phase or B phase two phases, the wiring of the winding can be reversed in the direction of the motor.


6) Power Interface:


Using DC power supply, operating voltage range dare to 18-40VDC, power supply power greater than 100W.


7) Indicator light: The drive has a red and green two LEDs. Where the green light is the power led. When the drive on the green light is always lit, the red light is the fault indicator light, when there is overvoltage, overcurrent failure, the fault light is often lit. After the fault is cleared, the red light is extinguished.


In the event of a drive failure, the failure can only be cleared by re-power and re-enabling. 8) Installation instructions: The driver's dimensions are: 96x60.5x24.5m, An Zingkong distance is 90mm, can be horizontal or vertical installation, construction using vertical installation. When installing. It should be pressed close to the metal cabinet for the benefit of heat dissipation.
