Mitsubishi VFD All Clear Factory Reset

Description of the problem:

If you are trying to get your spindle to run and have changed a bunch of parameters and are still not successful, it is sometimes helpful to do an "all clear" and start over.

 

Solution:

For the Mitsubishi D700 VFD, do the following:

  1. Press "PU/EXT" to put the VFD in PU mode

  1. Press "MODE" until you see "P 0"
  2. Scroll dial backwards until you see "ALLC"
  3. Press "SET"
  4. Set the value to 1 using the dial
  5. Press "SET"
  6. Cycle the power to the VFD (power down fully, then power up)

 

At this point, the VFD should be reset to default values. Next, for typical spindles and setups, set the following values:

 

Change parameters 3, 18, and 125 to your spindle's Maximum Frequency.

Change parameters 72 and 73 to 10.

 

It may be necessary to further complete some basic parameters according to the Installation Guide starting on page 10:

Removing the Computer from a X15-250 Control

 

Description of the problem:

It may be necessary for you to remove the PC from the control for repair or other reasons.

 

Solution:

To remove the computer from an X15-250 Control do the following:
NOTE: *Consider taking photos of your setup as you go so you can be sure to get things put back as they originally were
 
1. Remove the back panel on the control to be able to access the connections to the computer (your back panel may look a little different but concept is the same).

2. Unplug all cables going to the computer

3. Remove the screws around the monitor on the front

4. Slide the computer (with screen) out the front. NOTE: There is a foam type gasket around the frame of the monitor that seals pretty well and can make it difficult to get the computer out. You may need to work at it a bit, but if the front screws are out that should be all that is holding it in. Just be careful not to bend it or otherwise put too much pressure as the screen can crack).
 
5. The screen is attached to the PC with screws along each side. Remove the screws and screen can be detached. NOTE: There are likely plastic/poly spacers between the monitor and PC frame. These will likely fall out of place when you remove the monitor. Taking photos first can help to know how they go back together.
 
*To access the internals of the computer remove the screws holding the back cover on the computer box. Remove it slowly and watch for the CPU fan wire and note where it is plugged into in case you need to remove it or it gets pulled off inadvertently.

Setting Debounce Level

Description of the problem:

Debounce is the number of pulses that a switch must be stable for it's signal to be considered valid. For example, electrical noise can cause issues with limit switches being triggered. Debounce can be elevated to ignore the noise.

 

Solution:

To raise the debounce level, follow these steps:

  1. In Mach3, open Config -> General Config...

  1. Adjust the debounce interval; level should not be set higher than:
    1. Apollo I: 2500
    2. Apollo III: 100
    3. Interpreter 1000: 100
  2. Click [OK] to save changes

In Mach 4, go to Configure>Plugins>HiCON

How to Use Documentation Library

Welcome to the MachMotion Support Documentation Library.

Here is a quick overview of certain screens you may see and various functions available on each screen.

 NOTE: When performing a search, it is often helpful to use quotation marks. For example searching for M222 will likely not produce any search results, while searching for "M222" will. Quotation marks are not generally helpful if searching for longer strings of text because it tries to find an exact match and the word order can be different. Generally shorter, more precise searches, with quotation marks yield better results. Start with that and if not finding anything, then search without the quotation marks.
