Question #: 14189

Question: Can your controller run a AMC analog DC servo driver model 12A8E ???????

Current Solution

To my knowledge, the 12A8E cannot be controlled by our interface boards. We use a pulse train that work with stepper motors (step pulse for rotation and high/low signal for direction).

  • Please advise correct wiring from PLANETCNC USB controller Mk3/4 to motor driver.
  • How can I connect the Pokeys57CNC controller to a DRV8825 / A4988 expansion board?

    The DRV8825 driver IC by TI (Texas Instruments) has two main connections called STEP and DIR. These are the two main connections that you need to use to connect to the Pokeys57CNC controller. You also need to connect the positive digital voltage pin (5V) from the Pokeys57CNC controller's motor connector to both the reset and sleep pins. The GND pin from the Pokeys57CNC motor connector is connected to the GND pin of the DRV8825 driver. The enable pin of the DRV88525 can remain unconnected.

    There is a trimmer potentiometer on the DRV8825 that can increase or decrease the amperage setting for the motor. Depending on the DRV8825 board you purchased, there may be two pads to determine the amp setting while turning the trimmer (in the voltage setting on your multimeter).

    The A1 and A2 is connected to one of the motor's coils and B1 and B2 is connected to the other motor's coil. There is a pin on the DRV8825 called VMOT that you will connect to the power supply (max 45VDC) and the GND pin next to the VMOT is the V- for the same power supply.

    I hope this helps. If not, please add additional information on this thread.

    Additional Information:
    I followed (to the best of my ability) the instructions provided to my original question, but I did not receive successful results. When I followed the instructions and connected the ground pin from the Pokeys57CNC motor connector to the DRV8825 / A4988 expansion board, it stops the communication between the Pokeys57CNC board & the motors 1-3 that I had working previously. The DRV8825 / A4988 expansion board will be the fourth driver I am connecting to the Pokeys57CNC. The previous three drivers are PoStep-60's if that helps understand the issue.

    Prior to hooking up the ground pin (I used pin 10 from the Pokeys57CNC motor connector) to the DRV8825 / A4988 expansion boards ground pin, I was able to see the power being applied via the red LED being illuminated on the DRV8825 board; after this new configuration the light is not turning on.

    With the new recommended setup, I used a heat shrink solder piece to add the shunt for the connection to the sleep pin. The connection to the sleep pin is where I believe my issues are stemming from. I must be connecting it to the incorrect pin (within the 9 pin layout on the DRV8825 / A4988 expansion board). Do you have any reference to the 9 pin pinout on the A4988 expansion board? I double checked the pinout provided on the Texas Instruments page, but it only gives clarity to the pinouts on the DRV8825 board itself. After reviewing their documentation, I tried connecting the 5v (pin 9 from the Pokeys57CNC motor connection that's split to connect with the reset pin on the DRV8825 / A4988) wire directly to the terminal on the DRV8825 board and that didn't work either.

    Any help or clarification you can provide would be greatly appreciated!

  • I get a "communicating unsuccessful" when using LaserCAD and the AWC608 Laser controller

    If you are getting the "Communicating Unsuccessful!" error when you are trying to communicate between LaserCAD and the AWC608 Laser Cutter and Engraver controller (after you have already tried installing the USB driver from the LaserCAD setup procedure), these are the steps you will need for a successful communication:

    - Open the Device Manager window (right click on the start menu and select Device Manager)
    - When you plug the USB cable from the AWC608 Laser Cutter Controller (USB Type B connector) to the computer, you should see a new item in the Device Manager, possibly under "Ports (COM & LPT)", or under "Other Devices". It may show as an item under "Other Devices", possibly FT245R and has an "!" in a yellow triangle.
    - Download the latest FTDI drivers from: http://www.ftdichip.com/Drivers/D2XX.htm
    - Unzip the files to a folder that can be easily browsed.
    - Right click on the item that appeared in the Device Manager when the cable was plugged in between the Laser Cutter AWC608 controller and the computer.
    - Click on update driver
    - Select the procedure to manually install the driver and browse to the folder containing the FTDI driver and follow the step in the driver installation wizard.
    - The item should now be located under the "Ports (COM & LPT)" and should be named "USB Serial Device (COM#)". The # will be the number you will use in the LaserCAD software.
    - In the LaserCAD software, click the "Select Mode" at the far top right of the Laser CAD user interface.
    - Make sure USB mode is selected.
    - If the Machine name with the correct COM number is listed, select it and exit the dialog window. Otherwise, click on "Add" and fill in the details with the new COM number.

  • How are limit switches connected to the AWC708 controller?

    If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

    For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

  • hey, where can i see the steps how can i control 3 or 4 step motor? can i use the Axis Electronics Combo? or i need to connect controller?

    Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
    The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
    Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

  • IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

    I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

  • I have the USB controller board and the 8825 step driver. I need a wiring diagram between the two. Specifically, what does the GND pin on the X-axis connect to? Also, what does the 5V pin on the driver connect to?

    If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

    If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

    PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
    PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
    PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
    PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
    PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

    Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

    You can find a wiring diagram here:
    https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/

    The CP terminal is wired to the step terminal on the 8825 step driver.
    The CW terminal is wired to the direction terminal on the 8825 step driver.
    The GND terminal connects to the GND on the 8825 step driver

    The 5V connector on the driver simply powers the logic side of the chip and needs to connect to VCC pin on the keyboard jog.

  • Hello I recently read your site and have a question. I have a driver model DM2722A but I can't connect it to my usb controller due to the fact that the driver is not marked enable, but instead it is marked: mf-, mf +, alm-, alm +. I will be very grateful if you explain to me the meaning of the latter and tell me what should be related to "enable" Thanks in advance!

    Not a problem. The ALM is rather self-explanatory as this is a closed-loop stepper motor and driver that you are using. The ALM (alarm) is a signal that is used to tell the driver/controller that the motor is not in the same condition that the driver expects. In a closed-loop system, the motor has an encoder that tells the driver exactly how many steps that it turned, and if this value does not coincide with the driver's outputted number of steps, and within a specified amount of time, the alarm will trigger so the system can stop and the workpiece can be salvaged.

    The MF is simply a signal that tells the driver that there is impending direction and step pulses coming. If the MF signal is high, then that is similar to an enable signal.
