Question #: 5764

Question: How to I calculate RPM based on hertz displayed/set on the 2.2kw VFD (110V AC version)?

Current Solution

To calculate RPM use this formula, in which you will have to find RPM's when you have Hz.
1 RPM = 0.01666666667 Hz
Formula: 0.01666666667 × RPM = Hz
On our VFD if you select the >> button about 3-4 times, it will change from Hz, A, or ROTT.
When the LED's are lit on Power, FOR, and ROTT, you should be able to see the RPM the spindle is running at, our maximum setting for these spindles is 400Hz / 24000 RPM.

  • How to display RPM instead of frequency on the VFD? I have the 2.2kv 110 volt spindle and inverter.

    There is a button on the front of the VFD that will cycle through RPM, Freq, and a few other readings. If there is a >> button on your VFD, that will work. If there is a mode button on your VFD, that should works as well.

    Additional Information:
    There is a >> disc button but it does not cycle through the display modes.

    Additional Information:
    Is there a parameter setting to make this button work to cycle thru the display modes?

  • How to configure 2.2KW VFD for Modbus communication with Mach3

    It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

    The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

    You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

    Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

    You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
    - PD001 - value 2 - Enables with communication aspect of the VFD
    - PD002 - value 2 - Enables frequency control from the communcations port
    - PD163 - value 1 - VFD address
    - PD164 - value 1 - Baud rate of 9600 (speed of the communication)
    - PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

    Copy the dll file to the PlugIns folder of mach3.

    Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

    Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

    No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

    Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

    You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.



    Additional Information:
    This looks easy enough, however, the VFD that came with my spindle is made by Huajiang, not a Huanyang. The parameter codes are different and do not line up with the ones offered in this response.

  • How can i calculate how much can carry my stepper motor? i have these informations: (Detent Torque: 2.2N.cm; Rotor Inertia: 54g.cm2; Holding Torque: 40N.cm). It's a nema 17

    The holding torque will provide the best information for the calculation on how much your stepper motor will carry. But first, when you say carry, do you mean how much weight it can lift, how much inertia it can withstand during an acceleration and deceleration state or how fast it can accelerate or velocity it can maintain under load from the milling process?

  • I JUST RECEIVED A REPLACEMENT SPINDLE (2.2KW 220V). HOWEVER, WHEN ATTEMPTED IT USE THE NEW SPINDLE, WOULD ONLY REACH 1500 RPM. IS THERE SOMETHING NEED TO CHANGE ON CONTROLLER?

    VFD settings........
    1) To program the VFD, wire it up, plug it in. It takes several seconds to come to life.

    2) Push the PRGM button to enter programing mode.

    3 )Push the SET button. The display will read PD000.

    4) If you push the SET button again, it will display the present setting of PD000.

    5 )By pushing the up or down arrows, you can change the setting to whatever it needs to be. (This is just an example. PD000 needs no changes)

    6)Push the SET button again to lock in the setting of PD000 and advance to the next number, in this case, PD001.

    7) Push the SET button and it will display the present setting of PD001. Again, use the up and down arrows as necessary to set PD001, then push SET again to lock it in.

    Note: You can also scroll through the PD numbers with the up and down arrows.

    8) make all settings this way.

    9) by pushing the SET button you can scroll through the settings. First push of SET moves to the next number, second push displays it's setting, third push moves to the next PD number.

    Note- If you take too long, it will leave the programing mode on it's own. If it does, just push PRGM again to return to programing mode. Then press SET and continue what you were doing.

    10) Start with PD013. Set it to 1, which returns the settings to the factory settings.

    11) Then set PD005 to 400, PD004 to 400, and PD003 to 400 IN THAT ORDER.

    12) Then set the following: PD041=8, PD144=3000

    13) Set PD209=50

    That's it for the programing. You should get 24000RPM when you push RUN.

  • I want to know when the second video on vfd (YL-600 2.2KW 220V) parameter will be available?

    We will be starting that video shortly. We want to make sure we convey the information clearly. The parameters on the VFD are extremely extensive and is difficult to explain the parameters that will make sense to the average customer. We pride ourselves on making videos that send a clear message to customers and viewers that have never seen this technology before. Making an educational video of this topic is difficult.

  • How can I convert RPM to hertz Hz?

    1 RPM = 1/60 Hz
    1 RPM = 0.01666666 Hz.

    So, say you wanted to know the Hz for 12,000 RPM

    (12,000 Revolutions / Minute) / 60 = 200 Hz
    or
    12,000 RPM x 0.016666 = 200 Hz

    If you needed to determine the RPM from the Hz, then

    RPM = Hz x 60

    So, say you wanted to know what RPM is for 400 Hz:

    60 x 400 Hz = 24,000

  • Is 1000W voltage converter (110V to 220V) enough for 2.2kW spindle?

    Ideally, the spindle VFD should use an actual 220V socket that contains the minimum amp fuse that will allow the appropriate draw for all of the items that will be plugged into that socket. If you elect to use a boost converter, the 2.2kW spindle VFD will need a 2200 watts or more.

    My brother is using 1000W and told me his spindle is working just fine. Is it safe to use 1000W ?

    I still can't recommend using a 1000W converter.
