Product Overview
3MD560 is a latest high subdivision three-phase stepper motor drive, suitable for drive 57-86 seat NO of various brands three-phase stepper motor. Drive use advanced sine current control
 Technology, so it obviously improved the noise and riding stability of motor.  Compared with most other subdivision drive products on the market, the calorific value of 3MD560 drive and motor reduce more than 15%-30%.  Drive and three-phase stepper motor can improve position control accuracy, so particularly suitable for low noise, low heating motor, occasions with high stability and high requirements.
 

Main Application Fields
Suitable for all kinds of small and medium-sized automation equipment and instruments, such as engraving machine, marking machine, cutting machine, laser typesetting, plotter, numerically controlled machine tools, automatic assembly equipment, etc. The application effect is very good for little noise and high speed equipment.

Control Signal interface Description

Name	Function
PUL+(+5V)	Pulse control signal: pulse rising edge valid; PUL- high level 4-5V, low level 0-0.5V. In order to reliably respond pulse signal, pulse width should be more than 1.2μs. Using +12V or +24V, it needs to cascade resistance.
PUL-(PUL)
DIR+(+5V)	Direction Signal: high/low level signal, in order to ensure motor to reliable reversing, direction signal should be built before pulse signal at least 5μs. The initial direction of motor be concerned with motor's wires, exchanging any two of three-phase winding U,V,W can change initial running direction of motor, DIR- high level 4-5V, low level 0-0.5V.
DIR-(DIR)
ENA+(+5V)	Enable signal: The input signal is used as enable or forbid. ENA+ connect 5V, ENA- connect low level(or internal light coupling conduction),drive will cut off any phase current of the motor, which no respond stepper pulse. If you don't need the function, keep dangling enable signal.
ENA-(ENA)

 
Power and motor interface description

Name	Function
GND	DC Power Ground
+V	DC power positive pole, +18V-+150V any value is OK, but recommended value is about +36VDC.
U	Three-phase motor U phase
V	Three-phase motor V phase
W	Three-phase motor W phase
