MACH3 engraving machine CNC 57 86 stepper driver Board 2M542AH AP50

MACH3 engraving machine CNC 57 86 stepper driver Drive 2M542AH AP50 Description: 1. The main driver of 57, 86-type two-phase hybrid stepping motor, 2. The number of subdivision 14 species, the maximum number of steps is 256 subdivision; 3. The operating current range of 1.0A~6A, output current total have 11 files; 4. With automatic current control function, the current flow is adjustable semi-automatic, this feature is no other drives of the same type, which can adjust the intensity of the motor locked when no impulse control. 5. The drive voltage DC power supply. Operating voltage: DC 18~85V voltage, do not exceed the maximum operating voltage, it is recommended to use a DC 60V or less. 6. This paragraph has driven decay mode adjustment function, this function is the same type of drive is not the other, it can better match the different motors, vibration and noise will be reduced to the lowest. 7. With undervoltage and overvoltage protection. Function Description: Output current setting: the potentiometer setting driver output current, the output current total have 11 files. The number of subdivision setting: The SW1-SW4 this four dial switch to set the number of micro-step subdivision the drive, which has 14 files micro-step. When users set the micro-step, you should stop the drive to run. Automatic current function: Users can through SW7, SW8 to set the drive automatic semi-flow feature. Attenuation setting: the SW5-SW6 This two DIP switches to set the drive decay modes. Signal Interface: PUL + and PUL-control pulse signal positive terminal and a negative terminal; DIR + and DIR-signal for the direction of the positive terminal and a negative terminal; EN + and EN- is the enable signal of the positive terminal and a negative terminal.
