    Introduction

    2DM556 is newest digital stepper motor driver launched by JMC, using the latest 32-bit DSP control technology, the user can set any segment within 25600 and multi-range current value within rated current,with built-in micro technology,2DM556 driver greatly improved stability and reduced noise under subdivision. Integrating automatic parameter tuning function inside.it also can adjust the optimal operation parameters automatically for different motors to maximize the performance of the motor.

Signal

     Function

                                  Descriptions

PLS+

Input signal positive end

Connected to + 5V power supply, + 5V ~ + 24V can be driven, above 5V need current limiting resistor.

PLS-

Pulse signal

Falling edge, pulse from high to low whenever the motor step. Input resistance 220Ω, requirements; low 0-0.5V, high 4-5V, pulse width <2.5uS.

DIR+

Input signal positive end

Connected to + 5V power supply, + 5V ~ + 24V can be driven, above 5V need current limiting resistor.

DIR-

Direction control signal

Used to change the direction, input resistance 220Ω, requirements; low 0-0.5V, high 4-5V, pulse width <2.5uS.

ENA+

Input signal positive end

Connected to + 5V power supply, + 5V ~ + 24V can be driven, above 5V need current limiting resistor.

ENA-

Motor release signal

Off active (low) when power motor current, the drive stops working, the motor is in a free state.
