Introduction

The MD5042 is a high performance microstepping driver using the most modern technologies. It can be used to drive 2-phase or 4-phase hybrid stepper motors (bipolar or unipolar). Thanks to an advanced technique of constant current management, it is possible to make the best use of the characteristics of your motors. The 3-state current control technology allows precise control of the current in the motor windings with low ripple and therefore less heating.

Applications

Utilisable avec une large gamme de moteurs pas à pas Nema 17 et 23, et pour différents types d'application tel que des tables XY, des machines de marquage, de découpe laser, de gravure ou des machines de placement. Particulièrement recommandé pour des applications nécessitant de faibles vibrations, des vitesses élevées et de la précision.

Pin Function

Details

PUL﹢(+5V)

Pulse inputs: In PULSE/DIRECTION mode, each rising edge on this input causes a step forward. Depending on the application of the signal to the PUL+ or PUL- input, the input will be active from 4 to 5V or from 0 to 0.5V. In CW/CCW mode, the input is used to advance one step in the CW direction. The minimum pulse duration is 1.5µs. For use with control signals greater than 5V, an additional series resistor is required.

PUL- (PUL)

DIR+ (+5V)

DIR input: In PULSE/DIR mode, this input is used to select the direction of rotation. In CW/CCW mode (mode configuration by jumper J3 in the case), the input is used to advance one step in the CCW direction. To ensure quality movements, a change of direction must be followed by a delay of at least 5µs before sending pulses.

DIR- (DIR)

ENA+ (+5V)

Enable input: This input is used to activate / deactivate the motor supply. At + 5V, the power is activated. At 0V, the power is deactivated. If this input is not connected, power is activated.

ENA- (ENA)

Note:  drivers are set to PULSE/DIRECTION mode by default.
