  • Page 5: Power Terminals And Configuration Jumpers

    POWER TERMINALS AND CONFIGURATION JUMPERS Regulated +5VDC@ 1A is required to power this board. WARNING Check the polarity and voltage of the external power source and connect the 5VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board, and/or the power source.

  • Page 6: External Enable Pin

    External Enable Pin. The card must be provided with a 5VDC signal to enable operation. This feature has been added to externally control the status of the outputs. An external switch or a Safety Charge Pump can be added to provide the enabling signal. When the enable signal is not present, output signals send high impedance state.

  • Page 7: Safety Charge Pump "Schp". (Pin 17)

    Safety Charge Pump “SCHP”. (Pin 17). This board takes advantage of Mach ability to send a specific frequency through one of the pins of the parallel port when the program is in control of the system. CNC machinery can be very dangerous, and you could have a risk of the machine doing something different that what you intend the machine to do if the program loses control of your system.

  • Page 8: Controller Selection Jumpers (Ieee1284)

    Selecting the SCHP operation mode The Safety Charge Pump can be activated or deactivated depending on the jumper position 1-2: SCHP OFF 2-3: SCHP ON Note: When the Safety Charge Pump is activated, the EN terminal is active and a valid SCHP signal is present, pin 17 will go high.

  • Page 9: Variable Speed Control

    VARIABLE SPEED CONTROL This function lets you control your spindle with PWM signal. It converts the PWM signal into an analog (0-10VDC). This function can also be used on many DC motor controllers by replacing the potentiometer that controls the speed. Requirements: It requires a power supply external +12VDC@ 30mA for the analog output WARNING: To keep the output signals optoisolated, these must not have...
