VFD Parameters¶
Warning
All Avid CNC Plug and Play Spindle / VFD Systems come pre-configured with the correct VFD parameters. Do not change a VFD parameter unless our support team or documentation specifically directs you to do so. Setting an incorrect VFD parameter can cause a safety hazard or result in damage to your machine.
In some cases it may be necessary to change certain parameters on the VFD. Reference the System Identification page to determine the VFD ID of your Plug and Play Spindle / VFD System. For VFD IDs A1, C1, C2, D1, and D2, follow the How to Set Delta VFD Parameters section. For VFD IDs E1 and F1, follow the How to Set Mitsubishi VFD Parameters section. If you have any questions or need assistance, please Contact Us.
How to Set Delta VFD Parameters¶
Warning
It is recommended to have your CNC Controller turned off and Mach4 closed while changing VFD parameters.
When you are instructed by the our support team or our documentation to change a VFD parameter, you will be given a parameter such as "04-12". This is an example parameter that will be used in these instructions.
- With the Spindle Controller powered on, locate the digital keypad on the VFD.
- Press the Enter button once.
- Use the ▲ and ▼ buttons to until you see the desired parameter group. This is "04" in the example parameter.
- Press the Enter button once.
- Use the ▲ and ▼ buttons to until you see the desired parameter. This is "12" in the example parameter.
- Press the Enter button once and you will now see the current value for this parameter.
- Use the ▲ and ▼ buttons to enter your new value for this parameter.
- Press the Enter button once to set the new value.
- Press the Mode button twice to return to the starting display.
- The new parameter has now been set and it is safe to power back on your CNC Controller and open Mach4.
How to Set Mitsubishi VFD Parameters¶
Warning
It is recommended to have your CNC Controller turned off and Mach4 closed while changing VFD parameters.
When you are instructed by the our support team or our documentation to change a VFD parameter, you will be given a parameter such as "3". This is an example parameter that will be used in these instructions.
- With the Spindle Controller powered on, locate the digital keypad on the VFD.
- Press the PU/EXT button once.
- Press the MODE button once.
- You should now see the VFD in PU and PRM mode.
- Rotate the Dial until the desired parameter number is displayed.
- Press the SET button, which will display the parameter's current value.
- Rotate the Dial until the new value for your parameter is displayed.
- Press the SET button once to save the new parameter value.
- Press the MODE button twice.
- Press the PU/EXT button twice.
- The new parameter has now been set and it is safe to power back on your CNC Controller and open Mach4.
VFD Parameters for Spindle Changes¶
Info
It is only necessary to update these VFD parameters if you have an existing Avid CNC Plug and Play Spindle / VFD system and are only changing which spindle you are using. These parameters are only applicable for Plug and Play Spindle / VFD Systems with VFD ID A1.
3 HP Avid CNC Spindle¶
Info
This parameter change is for those with an existing 4 HP Plug and Play Spindle / VFD System who are changing the spindle to a 3 HP Avid CNC spindle.
Follow the How to Set Delta VFD Parameters section and set the following parameters:
| Parameter | New Value |
|---|---|
| 01-08 | 33.3 |
| 04-12 | 33.3 |
4 HP Avid CNC Spindle¶
Info
This parameter change is for those with an existing 3 HP Plug and Play Spindle / VFD System who are changing the spindle to a 4 HP Avid CNC spindle.
Follow the How to Set VFD Delta Parameters section and set the following parameters:
| Parameter | New Value |
|---|---|
| 01-08 | 25.0 |
| 04-12 | 25.0 |
VFD Parameters for Over-Torque Detection¶
Info
The following over-torque detection parameters are applicable for Plug and Play Spindle / VFD Systems with Delta VFDs (VFD ID A1, C1, C2, D1 and D2). If your system utilizes a different VFD, please Contact Us for support setting over-torque detection parameters.
Over-torque detection can be used to stop operation of the spindle (by activating a VFD warning fault) when abnormally high cutting loads cause the spindle to stall. We recommend starting with the initial settings below. These can then be fine tuned to achieve optimal over-torque detection for your specific machine and cutting environment.
Follow the How to Set Delta VFD Parameters section and set the following initial settings:
Initial Over-Torque Detection Parameters
| Parameter | New Value |
|---|---|
| 06-03 | 2 |
| 06-04 | 105 |
| 06-05 | 0.1 |
| Parameter | New Value |
|---|---|
| 06-06 | 4 |
| 06-07 | 220 |
| 06-08 | 0.1 |
3HP and 4HP Avid CNC Spindle¶
| Parameter | New Value |
|---|---|
| 06-03 | 2 |
| 06-04 | 105 |
| 06-05 | 0.1 |
8.7HP Avid CNC Spindle¶
| Parameter | New Value |
|---|---|
| 06-06 | 4 |
| 06-07 | 220 |
| 06-08 | 0.1 |
Fine tuning the over-torque detection can be done by adjusting parameter 06-04 for 3HP and 4HP Avid CNC Spindles, or parameter 06-07 for 8.7HP Avid CNC Spindles.
In the event of nuisance tripping (VFD faults under normal cutting loads), increase this parameter in increments of 5 until the nuisance tripping stops. If the spindle stalls under heavy cutting loads, but the over-torque detection does not stop the spindle, decrease this parameter in increments of 5. Further fine tuning can be made by adjusting the parameter in increments of 1.
