Stepper Motor Driver

We are credible provider of stepper motor driver (wzm-2h090mk).the stepper motor driver is made from best components and materials, which help in making it durable and efficient in performance. The stepper motor driver is equipped with the imported module to realize high frequency chopped wave. Stepper motor driver is featured with constant current driving, very strong anti-interference performance, good high-frequency performance, high starting frequency, optical isolation between the control signal and internal signal, current in optional, simple structure, stable operation, and less noise. Stepper motor driver can drive all 85byg85byg90byg series two-phase hybrid stepping motors with currency less than 5a. industrial applications :

• stage light
• automation
• instrument
• pos machine
• engraving machine
• bill printer
• industrial decal printer
• semiconductor diffusion furnace
• characteristics :
  • the maximal current of each phase of the driver is 5a. The current is adjustable in 16 steps
  • adopting the over current resistance patented technology
  • equipped with imported electric and electronic components
  • half current in optional
  • all input signals undergo optical isolation
  • the motor phase current is sine wave
  • control signal input connection : in order that the control system and the driver can communicate normally, avoiding the interference each other, we isolate the input signal with the optical coupling device inside the driver. The internal interface circuits of three signals are same. The common mode is 1) common anode mode: connect cp+. Dir+ and en+ terminals together as the common anode terminal, which is then connected to the external system +5v. The impulse signal is connected to cp- terminal. The direction signal is connected to dir- terminal. The enable signal is connected to en- terminal. 2) common cathode mode: connect cp-. Dir- and en- terminals together as the common cathode terminal, which is then connected to the external system gnd. The impulse signal is connected to cp+ terminal. The direction signal is connected to dir+ terminal. The enable signal is connected to en+ terminal. 3) differential mode: direct connection. if the voltage of the input signal exceeds +5v, the current limiting resistance r must be added in the external circuit to ensure providing 8 - 15ma drive current to the optical coupler inside the driver.
