VFD Parameter Changes¶
Overview
Newer Centroid-based EX control systems have been configured to interpret the spindle fault signal differently than previous CRP800 control systems. The spindle fault signal on your VFD controller needs to be configured as a "normally closed" signal under non-fault conditions to work with Centroid-based systems.
This configuration has the benefit of stopping machine operation if the VFD controller is not turned on or operational for any reason. This helps prevent the unintentional engagement of a non-spinning tool with your workpiece, which could cause tool breakage and strain on machine components.
Steps for Reprogrammming¶
1. Identify Your System¶
Avid has used VFDs from several manufacturers in our spindle controllers. Use the images in the sections below to help visually identify your VFD.

2. Program Parameters¶
Delta EL Series VFD¶
Change parameter 3.00 from the current value of 8 "Fault Indication" to a value of 22 "AC Motor Drive Ready". This will change the drive behavior to close the signal whenever the drive is in a non-error state, but will open it either during a fault or if the VFD is turned off.
| Parameter | Old Value | New Value |
|---|---|---|
| 3.00 | 8 | 22 |
- With the VFD powered on, press "Enter".
- Press the Up arrow until "03", the parameter group to change, appears on the screen and press "Enter".
- "00" will appear, indicating you are on parameter "00". Press "Enter".
- The parameter value "08" will be displayed. Press the Up arrow until you see "22". Press "Enter" to write the indicated parameter value.
- Your VFD is now ready to go.
Delta MS300 Series VFD¶
On Delta MS300 VFD systems, the parameter to change could be either 02.13 or 02.16.
To determine which configuration you have, look inside your spindle controller enclosure. If you have a relay (the DIN block device identified by the arrow), then you need to modify parameter 02.13. If you do not have a relay, modify parameter 02.16.
The fault parameter will have a value of "11", which means "Malfunction indication" and will only close the signal when a fault has occurred. Change this parameter to "9", which means "Drive is ready". This will close the signal whenever the drive is in a non-error state, but will open it during either a fault or if the VFD is not on.
| Parameter | Old Value | New Value |
|---|---|---|
| 02.13 / 02.16 | 11 | 9 |
- With the VFD powered on, press "Enter".
- Press "Mode" until you see the readout shown above, then press "Enter" to access the parameter controls.
- When "00" appears, press the Up arrow until "02", the parameter group to change, appears on the screen. Press "Enter".
- When "02.00" appears, press the Up arrow until:
- You have a relay installed: "02.13"
- You do not have a relay installed: "02.16
- Press "Enter".
- Press the Down arrow to change the parameter value from "11" to "9". Press "Enter" to write the indicated parameter value.
- "End" will appear, indicating your parameter has been accepted.
- Your VFD is now ready to go.
Mitsubishi VFD¶
On Mitsubishi D-series VFD systems, the fault behavior can be changed by editing parameter 192. In order to change this parameter, you may first need to enable parameter writing, which is controlled by parameter 77.
| Parameter | Old Value | New Value |
|---|---|---|
| 77 | 0 | 2 |
| 192 | 99 | 11 |
- Press "Mode" to change the parameter setting mode.
- Rotate the scroll wheel until parameter "77" is displayed. Press "Set".
- Rotate the scroll wheel to change parameter "77" from "0" to "2". Press "Set" to write the indicated parameter value.
- Rotate the scroll wheel until parameter "192" is displayed. Press "Set".
- Rotate the scroll wheel to change the parameter from "99" to "11". Press "Set" to write the indicated parameter value.
- Your VFD is now ready to go.
