JMC 2 phase hybrid stepper motor driver 2DM860H


Key Features

The new 32-bit DSP technology

* Optically isolated differential inputs (26LS32)

* Extra-low noise and vibration

* Built 500 high octave segments (segments selected value)

4,6,8 lines can drive two-phase stepper motor

Current settings can be arbitrarily choose between ratings

Stationary current is automatically halved

Pulse frequency response up to 250KHz

Overvoltage, undervoltage, short circuit protection

Alarm output function I / O ports

Alarm clear input ENA


Introduction

2DM860 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,2DM860 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.

     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.
