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

Product Name: 2 PHASE digital stepper driver MC425 for 42 stepper motor MC425 digital low voltage stepper motor driver, using the latest 32 bit DSP technology, suitable for driving 35, 39, 42 series motors, with excellent medium and low speed performance. It can set any subdivision within 64 and any current value in rated current, which can meet the requirements of most small equipment. With the built-in micro technology, even under low subdivision conditions, it can achieve the effect of high subdivision. The medium and low speed operation is very smooth, and the noise is 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 protection function, small volume. Electric index Instructions MC425 min rated max unit peak current 0.5 - 2.2 A Input voltage 18 24 36 VDC Control signal input current 7 10 16 mA Pulse frequency 0 - 75 KHZ insulation resistance 500 - - mΩ Interface definition (1) control signal interface Name function PUL Pulse input signal DIR The direction input signal is used to change the running direction of the motor. In order to ensure the reliable commutation of the motor, the direction signal should be Prior to the pulse signal, at least 5 s is established, the initial running direction of the motor is related to the motor winding connection, and exchanging any phase winding (such as A+, A- switching) can change the direction of the initial operation of the motor OPTO Pulse / direction / enable signal power terminal +, default external 5V, if +12V or +24V, need extra resistance ENA Enable to control a signal that is used to enable or disable drive output. When the ENA is connected to a low level (or an internal optocoupler), the driver will cut off the current in each phase of the motor so 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 (2) power interface Name function GND DC power earth +Vdc DC +，range：DC18V~36V. +24V Recommend A+,A- Motor A phase winding B+,B+ Motor B phase winding
