2 phase NEMA14 NEMA17 hybrid stepper motor driver DC24V 2.5A MC425 for 57 motor

Name: 2 PHASE digital stepper driver MC425 for 42 stepper motor

MC425 digital low voltage stepper motordriver, using the latest 32 bit DSP technology, suitable for driving 35, 39, 42series motors, with excellent medium and low speed performance. It can set anysubdivision within 64 and any current value in rated current, which can meetthe requirements of most small equipment. With the built-in micro technology,even under low subdivision conditions, it can achieve the effect of highsubdivision. The medium and low speed operation is very smooth, and the noiseis very small.

Can drive the 4 line, 8 line step motor;input voltage range: 18V~36VDC, maximum current 2.5A, 0.1A resolution,subdivision range: 400~6400ppr; signal input: single end, pulse / direction;built-in micro precision; current control the heating of the motor is reduced;the static current automatically halved; photoelectric isolation signal input,strong anti-interference ability; with over-voltage, over-current protectionfunction, small volume.

The direction input signal is used to change the running directionof the motor. In order to ensure the reliable commutation of the motor, thedirection signal should be

Prior to the pulse signal, at least 5 s is established, theinitial running direction of the motor is related to the motor windingconnection, and exchanging any phase winding (such as A+, A- switching) canchange the direction of the initial operation of the motor

Pulse / direction / enable signal power terminal +, defaultexternal 5V, if +12V or +24V, need extra resistance

Enable to control a signal that is used to enable or disable driveoutput. When the ENA is connected to a low level (or an internaloptocoupler), the driver will cut off the current in each phase of the motorso that the motor is in a free state and does not respond to step pulses.When this function is not required, the signal is left unconnected
