Question #: 13264

Question: Is the "1.5 kW (kilowatt) Water Cooled Spindle with Inverter (VFD)" spindle speed regulated? (Will maintain its speed under load)

Current Solution

Absolutely. These spindles do not get bogged down under load like routers will. The speed is regulated and current will adjust with the load.

  • I am interested in buying the water cooled 2.2 KW spindle for $339, how much does it weigh?

    The weight of the 2.2kW spindle without the VFD (variable frequency drive or inverter) is 11 lbs or 5 kg.

    The 2.2kW spindle with the VFD is 15 lbs or 6.8 kg.

  • It seems that the water cooling lines inside my 2.2KW spindle are clogged. Is there a way to unclogg them?

    You can use a compressor to unclogg the water lines of the spindle. We use this method and it works every time (so far).

  • HEY ! I HAVE PURCHASED A VFD WITH MATCHING SPINDLE 1.5KW AND CONTROL PROGRAM UCCNC. MY INTERFACE CARD IS DB25, THE QUESTION HOW DO CONNECT TO DB25 SO THAT CAN SPEED UCCNC? SINCERELY "CNC BEGINNERS"

    Identify the Control Signals: First, determine which control signals from the DB25 interface card are used for spindle speed control. Typically, these are PWM (Pulse Width Modulation) signals or analog voltage signals.

    VFD Configuration: Your VFD should be configured to accept the type of control signal your DB25 card provides. This involves setting parameters in the VFD that correspond to the type of input signal it will receive for speed control.

    Wiring: Connect the appropriate output pins from the DB25 card to the input terminals on the VFD. This usually involves connecting the PWM or analog output to the corresponding input on the VFD. Make sure to consult the manuals for both your VFD and interface card for specific wiring details.

    UCCNC Settings: Configure UCCNC to output the correct type of signal (PWM or analog) that matches your VFD's configuration. This is done through the software's spindle setup section.

    Test and Adjust: Run some tests to ensure that the spindle speed is being correctly controlled by UCCNC. You might need to tweak settings in either the VFD or UCCNC for optimal performance.

  • I HAVE A 2.2KW WATER COOLED SPINDLE WITH YL620-H VFD. THE VFD USES P#-## PROGRAM FORMAT. BELIEVE ALL CORRECT SETTINGS SETUP BUT WHEN TURN UNIT ON, IT SPINS AT ABOUT 200-300 RPM REGARDLESS OF WHAT FREQUENCY CHOOSE. DO YOU PARAMETERS IN THIS FORMAT FOR UNIT? THANK YOUR HELP. HUIBERT MEES

    You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

    For 200 RPM:
    Hz = 200/60 = 3.33 Hz

    For 300 RPM:
    Hz = 300/60 = 5 Hz

    Conversion to RPM:
    If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

    RPM = Hz × 60

    Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

  • What is the Greenbull average power consumption in conjunction with 2.2KW spindle?

    You can determine you overall CNC machine current consumption be adding your spindle power plus your CNC motion power and the power that your computer requires.

    the formula to understand the current of each component is watts = volts x current, or W = V * I, or with some algebra, Current (I) = Watts (W) / Volts (V)

    For example:

    Spindle:
    The 2.2 kW = 2200 watts and you can find the current by taking the input voltage of 220 volt and get the current using the above formula: 2200 W / 220 V = 10 A (Amps)

    CNC motion electronics:
    The power supply that comes with our machines is generally 8.8 A

    Computer:
    The computer that you use to control the CNC machine will have a specific wattage. Let's say the watts is 500: 500 W / 110 V = 4.5 A

    Add them up: 10 A + 8.8 A + 4.5 A = 23.3 Amps

  • 1.5KW water hose 1/4" ID - 3/8" OD does not fit in spindle fitting with ID 0.31"

    If you are using a silicone tube with a 1/4” ID, it will fit the nipple of the 1.5kW spindle water connections measuring an OD of 0.31”. The silicone will stretch and you will need to use water or saliva to help the tube fit.

    The tube ID being smaller than the nipple will help the seal prevent water from leaking.

  • THE GANTRY MOUNTED SPINDLE WATER COOLER PUMP THAT I PURCHASED DOES NOT OPERATE NO MATTER HOW CONNECT THREE WIRES TO TWO WIRE POWER SUPPLY.

    The 12V power supply has 3 terminals for AC in: N, L and earth ground. The output of the 12V power supply has 2 DC + and - terminals. Cut the connectors off of the ends of the fan and pump wires. Strip the red and black wires of both units. The fan will connect to the 12V power supply red to the + and black to the -. The pump will connect in the same way, but the white is not connected.

    If you have a pump that has a grey and black wire on the large connector, the grey is the 12VDC V+ wire and the black wire goes to the V-. The extra wire does not need to be connected.

  • Will your 2.5 KW spindle work with my Hitachi WJ200-022SF VFD and does it have a thermal couple temp output?

    From reading on the Hitachi WJ200-022SF VFD, it seems as it will work just fine with this VFD. However since we have not tried this cross match, I would carefully take each connection and setting into great consideration and detail on both the Hitachi recommendations for setup, as well as our spindles recommended setup.
    Our spindles do not have a thermal couple temperature output.

  • WHAT ELECTRICAL CABLE DO I USE TO CONNECT VFD INVERTER SPINDLE?

    The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

    The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

    Currently we use 20AWG 4 conductor.

  • I PURCHASED A VFD AND SPINDLE FROM FRIEND, HIS SET UP IS 220. DON'T HAVE 220 IN MY SHOP. QUESTION CAN USE YOUR 110 WITH THIS SPINDLE??

    Depending if the spindle can work with this specific VFD, it might be possible. However we would not like to risk you working unit, with a possible match so we would like more details on your specific model and any information available on the spindle itself.

    Response
    The only info on the spindle is 2.2KW 400HZ 220V. Made by Zhong Hua Jiang.

    Was originally on a Delta C200 vfd. That is 220 single phase.
