### Question #: 14904

Question: what size circuit breaker should I use with the 2.2KW VFD?

Current Solution

The 2.2kW spindle has a power rating of 2.2kW or 2200 watts.

If the VFD AC voltage input is rated for 220 volts, then 2200 watts / 220 volts is 10 amps, so a 15 or 20 amp breaker will work.

If the VFD AC voltage input is rated for 110 volts, then 2200 watts / 110 volts is 20 amps, so a 25 or 30 amp breaker will work.

• what depth increment should I use for pocketing and profiling with the 1/2" end mill?

The pocketing depth per pass will depend on the hardness of the material, the router/spindle you are using and on the melting point of the material. Use the feedrate that you would normally use for the size and type of end mill. You will need to test the depth per pass, starting at the full depth of the pocket. The spindle should have no problem, but if you are using a router, then it may bog down, so easing up on the depth per pass is recommended. If the spindle/router has no problem at the depths you are using, then you need to evaluate the edge finish to determine if it is acceptable. If it is not acceptable, then ease up on the depth per pass. Keep doing these steps until you have the finish and precision you expect.

• What wire size to use from VFD to 2.2kW spindle?

We use 16 AWG wires between the spindle and the VFD. This wire size has a maximum capacity for 22 Amps, a good buffer to eliminate any possibility for overheating. The 2.2kW using 220V may draw up to 10 Amps (220 x 10 = 2200).

That is, all three wires are sharing the total current draw.

• What size of wire do you use to connect the VFD to the 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.

• How do I program the 2.2kw VFD to jog with a Digital Input

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

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.

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.

• What wiring should I use to connect two motors for one axis?

Yes, you can use 2 motors in the same axis output, however you will still need a driver for that motor! Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

Also you can run a slave motor using another axis on the board, and setting it up in the Planet-CNC settings.

Planet-CNC/File/Settings/Axes, here you will enter 3 in the Number of Axes location, and then change the Function of the Axis 4 to Slave 1. There you will have the 4th axis or A-axis be a slave for the x-axis.
Slave 1 - X-Axis
Slave 2 - Y-Axis
Slave 3 - A-Axis
Slave 4 - B-Axis
Etc...

• Are the VFDs and pumps compatible with the european electric circuit (230V/50Hz) and what kind of connectors will be delivered?

The VFD (Variable Frequency Drive) is not supplied with plugs, cable or connectors. You provide the cable and power plug or connector for the VFD. All you need to do is get an extension cable and expose the three wires of the cable and connect them to R, T and Ground. Please see the datasheet on this page for wiring information: https://www.buildyourcnc.com/item/spindle-inverter-2!2kw-spindle-novfd

Our pumps only have a 110 volt input, so you will need to purchase the pump in your country.

• How do I determine what CAM program I should use?

There are several specifications related to CAM software that you will need to consider.

1. The CAM software will need to be able to offer the features that match that of the machine you select to perform the fabrication. Some of these machines include, standard 3 axis vertical CNC milling machine, turning machine, and 4 or 5 axis CNC machine.

2. The CAM software will need to contain the features that you feel are necessary for how you will apply the machine. For example, are you making signs? Are you milling parts for a machine? There is a wide array of CAM software that will work well for one application and not another.

3. The CAM software will need to work well with your workflow and processes, and have the user interface that you prefer.
