3 Phase Digital stepper driver series

LC3722A Nema42/51 digital stepper driver

   Features:


  1. High performance, low price
  2. With 16 scales constant torque moment subdivision, the maximum resolution of 60000 steps / turn
  3. The highest response frequency up to 200KPPS
  4. When the stepping pulse stops more than 1.5S, the coil current is automatically reduced to half of the set current
  5. Optical isolation signal input / output
  6. Drive current 1.3A / phase to 7.0A / phase 16 files adjustable
  7. Single power input, voltage range: AC110V-220V
  8 phase memory function (Note: the drive stops for more than 3 seconds after the drive automatically memorizes the motor phase at the time,

  re-  power or When the WF signal goes from low to high, the drive automatically recovers the motor phase)

    5PU+

    Input signal optically isolated positive terminal

    + 5V power supply, + 5V - +24 V can be driven, higher than +5 V need to take current limiting resistor

    2

    PU-

    DP9 = OFF, PU is the step pulse signal

    Falling edge is valid, when the pulse from high to low when the motor step, the input resistance of 220Ω, requires: low 0-0.5V, high-level 4-5V, pulse width> 2.5μs

    DP9 = ON, PU is the positive step pulse signal
