MACH3 Control board (V2.1). A special high speed chip is used to process the input and output (I/O) signals. It is capable of making the machine work stably, with the features of correcting and enlarging the signals that removing the unnecessary disturb signals. The computer LPT port supplies the power individually, separating from the power supply of other parts. Therefore, the computer and machine tool isolate effectively.There are 5 input signals, communicating with the host computer, which are isolated by the optical coupling. Among the optical coupling isolation, the P11and P12 are high-speed, which can be used for connecting main shaft encoder, or the same demanding signal as hand wheel A, B. 12V-OUT and 5V-OUT power output interface can be used to pick some necessary power, such as the hall sensor switch and the proximity switch. There are 5 input ports, set to limit, origin, knife, start, stop, spindle speed input, MPG input and any other one of the 5 functions. There are 12 output signal, which is allowed to controlling output, supporting as many as 6 axis linkage. Some of the output port is reusable functinality. Meanwhile, one port only can be used as one function.
There are 3 replays, P2, P3 and P4, which can support MACH3 control software programming. The relay's on or off can be controlled through the control of MACH3 software.Each relay has attracted indicating lamp, which is more intuitive and convenient. The 3 relays can be used to control the opening and closing of the liquid coolant, mist coolant, liquid state coolant and so on. They can also be used to control the electromagnetic valve device power switch. P2 port is for the spindle, P3 port is for the cooling liquid, P4 port can be defined. The high speed optical coupling isolation is used to control the rotational speed of spindle.
The output port is parallel port P1, which can output the PWM signal within 2.5KHZ. On the interface board , there is a D/A circuit, with PWM to a 0-10V. The circuit can output 0-10V level to control the inverter which only has analog speed control in the market. Thus it can control the rotational speed of the spindle. It is important that the PWM output and 0-10V output can only choose one in two.
They cant be used at the same time. Interface board can be connected with the cathode or total output to the stepper drive, or servo drive (servo driver must support the digital signal). The output is the 5Vlevel. Wide input voltage power supply: 15-32VDC.
The function of preventing reverse connection protection. 2 groups of output voltage: 5V and 12V voltage, 100MA output capacity.Note: There is an enhanced version. Power supply voltage has a wider range: 15-50VDC. Do not insert the USB line to the computer's USB port. Just insert a LPT line. It is more convenient and reliable. The current output ability of 5V and 12V voltage output can upgrade to 200MA. CW8060 high microstep stepper motor driver. DC power input type:24V80V. Mircostepping:1(1.8deg), 1/2,1/4,1/8,1/16,1/32,1/64,1/128,1/256. 1/5,1/10,1/25,1/50,1/125,1/250. Protect form: Overheated protect, lock automatic half current , error connect protect. The maximum pulse rate is 100KHZ. VCC+:DC power positive pole. Must guard against exceeding 80V. So as not to damage the module. A+, A-:Stepping motor one winding.
B+, B-:Stepping motor other winding. CP +, CP -:Stepping pulse input+5V (Rising edge effective, rising edge duration >10uS). CW +, CW-:Stepping motor direction input, voltage level touched off, high towards, low reverse.
1, When ambient temperature is high or working current over 3A, fix the module on big metal shell , or use axle flows fan dispels the heat, to make the module run reliably for a long time. 2, Half current automatically: if control machine not send out signal in half second, driver enter half current state of automatically for electricity saving, the phase current of the winding of the electric. 3, The fault phase is protected : When the double-phase electrical machinery is connected with driver , users are apt to connect the phase by mistake, thus would damage the driver seriously. The protecting circuit is within this driver, when users connect by mistake, the driver will not be damaged, but the electrical machinery runs abnormally, shake , and output is small. Please check whether the wiring of electrical machinery is a mistake.
Full current or half current choice. SW4:0=Full current;1=half current. Usually default setting is single pulse. High quality NEMA34 stepper motor. Note:We can manufacture products according to customer's requirements.
