3. Extend the ramp-up time
4. Decrease the torque and increase the set value.
5. Check if the motor is blocked and if there is a sudden change in load.
6. Check if there is a sudden chance in the power supply voltage.
7. Extend ramp down time
9. DC breaking is too high. Decrease DC breaking
10. Replace the inverter.
11. Check to see if there is a short circuit with the connection wire of the motor.
12. Extend the ramp-down time or add a breaking resistor.
13. Check the mains supply voltage and insure there isn't ant sudden change in voltage.
14. Send the inverter for repair.
15. Check whether the input voltage is normal
16. check whether there is a sudden change in load.
17. Check whether there is any phase missing.
18. Check the fan in the inverter. Is it spinning? Is it blocked? Does it have any foreign matter stuck on the fins of the fan? If so, clear the fan.
19. Check the ambient temperature in the space that the inverter is placed.
20. Check for adequate ventilation for the inverter where it is placed.
21. Check for jamming or any sudden change with respect to mechanical load.
22. Set the V/F curve correctly.
23. The motor is too small.
24. The motor is hot and the insulation of the motor degraded.
25. Check if the voltage has a large variance.
26. Check if there is a phase missing.
27. Contact the supplier

The Er.04 (if you are using the YL VFD), generally refers to the ramping up and ramping down of the spindle, but it can be a result of a short circuit between the VFD and the spindle. You can increase the time the spindle accelerates (ramps up to the set rpm/frequency).

The DL error usually means that there is a short in the wiring going from the VFD to the Spindle. First remove the spindle connection and run the VFD. If "DL" does not appear then this means the short is on the spindle itself. Remember to double check your wiring and to use heat shrink on the soldering points to prevent any shorts or arcing between the points.

The best way to determine how to control your VFD using Mach4 is to read the MAch4 manual found here:
http://www.machsupport.com/wp-content/uploads/2014/05/Mach4%20Installation%20Manual.pdf

You will find that there a a few ways to control the spindle/VFD on your CNC machine or CNC Router.
- The first and easiest is to have your VFD's power controlled by a relay. This will allow your spindle to have on/off control through Mach4 with an output pin.
- The second is to have a controller output a DAC voltage between 0-10 volts to control speed on the VFD/Spindle. There is a termial on the VFD to receive this signal line. The controller will also have an output that outputs a high or low and that can control the on/off on the VFD.
- The third, and more difficult of the three methods is to use a USB to Serial adapter (USB to USART or RS-485). The Computer plugs into the adapter using a USB cable and the adapter uses the RX/TX to connect to the VFD's terminals for communication. This will provide a great amount of control. Mach4 will need a plug-in to make this option work.

Is there a way to use Mach4 to control my VFD?

The current draw of the 220V VFD is 10 amps. Since the spindle is rated at 2.2kW, and the mains for the US 220V is in the range of 220V to 240V,

2200W/220V = 10A
2200W/240V = 9.167A

So, the rage of current draw will be between 10A and 9A, but it is advisable to provide a buffer of about 5 more amps if possible.

Yes, this 2.2kW spindle can definitely be used with a 2.2kW 220V Huanyang VFD as long as the spindle you select is also rated 220V.

Click the link to add information to this solution:
[78] Is this compatible with a 2.2kW 220V Huanyang VFD? Thank you.

Yes, you can control the VFD using the a relay.  You will need to connect the relay output (NO) to the forward terminal of the VFD and the gnd terminal.  You will need to look at the diagram for your VFD to determine which gnd to use in the set of terminals that is associated with the forward terminal.  The forward terminal may be called something else, but the manual will tell you (something like X1, or D1, etc.)

You will also need to change a parameter in the VFD to use the external terminals as opposed to the control from the control panel.

HOW DO YOU SETUP THE SPINDLE INVERTER VFD?

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.

Will this work with the brand called "best "vfd as well.
