Question #: 13975

Question: What would be your recommendation for "power supply 2 (24vdc)" connecting to USB motion card?

Current Solution

A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

  • What functionality is lost if 24V power supply not provided to "Mach3 USB Motion Card"?

    If the Mach3 USB does not have a 24V power on the limit switch/output/DAC side of the board, then those functions (limit switches, outputs and the DAC) will not work. If you have a spindle, you can use the 24V output from the VFD (Variable Frequency Drive) to serve as the 24V supply.

  • DO NEED LIMIT SWITCHES, IF SO WHAT IS YOUR RECOMMENDATION?

    Limit switches are not really needed for this level of a machine, but if you do want to use them, then you will need to connect them with shielded cable and ground the shield at both ends and any other non-used wire in the cable. Limit switches are very susceptible to the motor interference. You will also need to adjust the debounce in the software you will use.

  • Good evening, if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors. I have a 48V 12amp power supply. Thank you

    I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

    The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

  • What power supply would be adequate for the whiteAnt 3D printer?

    The whiteAnt will work with a 6 amp 12 volt power supply. If you add more peripherals to the machine, like heating bed, you will want higher current. Each motor draws 3.0 amps at full torque. Most of the time, only the x and y axes are moving at the same time, and the drivers are only allowing a max of 2.5 amps and they should be set for about 2.0 amps so they don't overheat (they have overheat protection and the LED will light up, so you will be fine if it does overheat, but your model may suffer). The remaining current will be enough to keep the hot end heated.

  • WE'RE GLAD THAT CDC HAS MADE A UNIVERSAL INFLUENZA VACCINATION RECOMMENDATION TO VACCINATE EVERYONE 6 MONTHS AND OLDER. WOULD YOU TELL US HOW THIS CAME ABOUT?

    Prior to the 2010-11 vaccination season, only children ages 6 months through 18 years and adults age 50 years and older were universally recommended for vaccination; recommendations for adults ages 19 through 49 years were targeted to people with specific risk factors, although other adults could be vaccinated if they wanted protection. Collectively, these targeted risk groups made up 85% of the U.S. population. During the 2009 H1N1 outbreak, additional risk groups were identified, such as obese individuals. The recommendation made by ACIP in February 2010 for universal vaccination simplifies previous recommendations, making it easier for healthcare providers to determine whom to vaccinate. The universal recommendation also makes it easier for patients to remember to get vaccinated every year.

  • ARE THERE RECOMMENDATIONS FOR THE PREVENTION OF INSTITUTIONAL OUTBREAKS INFLUENZA?

    The most important factor in preventing outbreaks is annual vaccination of all occupants of the facility, and all persons in the facility who share the same air as the high-risk occupants. Groups that should be targeted include physicians, nurses, and other personnel in hospitals and outpatient settings who have contact with high-risk patients in all age groups, and providers of home care to high-risk persons (e.g., visiting nurses, volunteers).

  • What relay should be used with your USB BOB for controlling mist/flood/spindle on/off?

    The relay that should be used with your USB BOB for controlling mist/flood/spindle on/off is one of the following options.

    You could get and use the Planet-CNC.com Output Board found here, http://www.planet-cnc.com/index.php?page=shop

    Or you could create your own setup using a resistor, solid state relay, transistor, and diode. You can watch this video, https://www.youtube.com/watch?feature=player_embedded&v=PJO_XoLL6lQ, to find out the correct way to accomplish this.

  • So I had my electrician hook it up as per your recommendations and nothing happens. Nothing lights up on the screen and nothing turns on. I have verified that the vfd that I was supplied is for single phase power and I have single phase power at my shop. It is a 220v vfd and I am supplying it with 220v. What do I do now? Is this vfd a bad one and do I need a new one?

    Was this VFD purchased from buildyourcnc.com and if so, what is the model number. If not, please provide the model number and we will attempt to determine the issue.

    Also, is this question related to a previous question you asked earlier? If so, please respond to that question with this new information.

    Many thanks.

    Additional Information:
    Yes it was purchased through your website, here is the number is YL600-2S-2K20

    Additional Information:
    Ok great. I will look into it.

    Is this related to the R S T and L1 L2 question that was recently asked?

    Additional Information:
    No

    Additional Information:
    It started with that but then once it was wired up it changed to this.

    Additional Information:
    Ok. Thanks. Please explain how you have the VFD wired to the 220v outlet.

    Additional Information:
    I have traced the black wire clear from the panel to the R terminal and the white wire to the T terminal and the ground to the E terminal. I have even used a multimeter on the terminals in the VFD while the wires are connected and the power is on, and I get 240V across the R and T terminals and 120 from R to Ground and from T to Ground.

    Additional Information:
    I still have not seen a response to my previous additional information. It has now been 5 days since then and I still have a non-functioning VFD, what should I do?

    Additional Information:
    My apologies. I didn’t see your latest wiring clarification response. Please connect the white (neutral) wire to the “S” terminal.

    Additional Information:
    So, i wired it up and now it does in fact power up. However, now it just gives me an ERR 02 code. What does that mean? the only manual that came with the VFD is all in Chinese. Do you have a book in english? Or a list of error codes?

    Additional Information:
    I have not seen a response to my previous comment. It has been a while since i have heard from you. What do i do next?

    Additional Information:
    Sorry about that. The Er 02 code in my manual says that there is an over-current at constant speed, over-current at deceleration or over-crrent at stop.
    The recommended actions in the manual says:
    1. Check whether the motor has got short circuit and whether the insulation of the output wires is good.
    2. Check whether the motor is blocked and whether there is a sudden change of mechanical load.
    3. Check whether there is a sudden change in he power supply voltage.
    4. Check whether the insulation of the output wires is good and whether the motor has got a short circuit.
    5. Extend the ramp down time.
    6. Replace it with an inverter (VFD) of larger capacity
    7. DE braking is too high. Decrease DC braking (this is only if you have a braking resistor connected).
    8. The inverter has failure. Please send it to the factory to repair.

    What I have done in the office is to check the resistance between the motor coils. The motor coils should have the same amount of wire winding on each coil. If there is a short circuit in this coil, the the resistance should be lower since there is less wire to travel. You can use a multimeter to check between pin 1 and 2, 1 and 3 and 2 and 3. The resistance should be generally the same.

    Additional Information:
    I worked threw all the other problems. the controller is now displaying Err 10. WHat does that mean.

    Can you provide a complete list of error codes. Or documentation to support this device you sold to me.

    id like to be able to integrate this thing into my growing business. i have been pretty unhappy so far with the lack of support. If you have any documentation, can you please send it to me. i cant be the only one having issues. Or even asking for help with these VFDs.
