3Axis 2 phase Nema 42 7A Stepper motor Driver ROUTER 110V-220V AC INPUT Controller + CNC MACH 3 /2 Breakout Board adapter stepper 
 
 The Drive is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is from 110V to 220VAC. It is designed for use with the 2 phase hybrid stepper motor of all kinds with 86mm to 130mm outside diameter, regulated phase current 1.2A to 7.0A. The circuit that it adopts is similar to the circuit of servo control which enables the motor run smoothly without noise and vibration. The highest micro step is 60000ppr. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, computer embroider machine, packing machine and etc.
 
 FEATURES

 The interface board
 provide the 12-wires OC output , the output port can drive the SSR ( solide-state realy ) directly.
 12-wires optical isolated common signal input
 all the input and output have the signal alarm
 single power supply 13-24VDC
 all the input signals of the PC parallel port are modified by the Schmitt Trigger and increase the anti-jamming capacity of the transmission of the digital signal
 Using Mach 2, 3 as the controlling software, makes the application of the PC as the industrial control possible
 as the lack of the IO of the PC parallel port, we add 3 axis 6bit independent Limit switch of the IO input
 compatible with all the pusle and direction signal of the Stepper or Servo driver , can control the lathe and milling machine to work
 the input part can connect to the mechanical switch , groove optocoupler, proximity switch , tool presetter etc.
 the interface board P1-P17 port correspond to the pin1-17 of the PC parallel port , the parallel port pin 18-25 is the GND.
 control the 2-wires electromagnetic relay output by the parallel P1 and P16 , this can control the cooling pump and lubricating oil pumpof the lathe
 the setup of the P17 in the Mach 3 for the charge pump can control the solide state relay output to increase the safety of the lathe.
 the P14 can provide the accurate 0-10V analog voltage for the main axis speed control signal , this can make the frenquency of the speed of the spindle
 the dimension: 170mm*115mm locating hole: 119mm*101mm
