How to calculate servo filters such as notch, low pass filters?

 

Unfortunately,

There is some problem on Power PMAC IDE(Version : 1.4.0.62)

Some sections of filter calculation tool on tune window are not appeared.

So, I cannot implement servo filter on Power Pmac.

 

How to solve it?

 

In addition,

I want to know how to calculate advanced filters including 7th polynomial filer and trajectory prefilter, adaptive control setup.

Please let me know how to calculate these filter with examples (case by case).

My experience with this is in Windows 7 the default screen resolution is 125%. In this case the tuning windows and system setup windows do not get properly scaled and the result is as you have described. If you change your screen resolution to 100% (which for some reason is not the default) then all the windows are properly shown.

Unfortunately,

I already set the screen resolution to 100%.

Few weeks ago, I had similar to problem in system setup window. I can clear it by having changed screen display resolution to 100%.

 

But, I cannot clear still this problem on tune window.

I do not know anymore, hopefully someone in California knows more. From the pictures it looks exactly like my system when the resolution is 125%, even the same things are cut off the same way. So it must have something to do with the program not properly adapting to the resolution. Perhaps changing the main resolution will help you get around the problem, mine is set for 1920x1080?

Hi kjcho,

 

I would try the following, however, I don't have a Korean version of windows so I can confirm whether it works or not:

 

Use at your own risk, the side effects are not known.

 

1. Be careful:

Create a restore point.

Export registry to a file to save it.

 

2. Edit Registry:

REGEDIT

Navigate to HKEY_CURRENT_CONFIG\Software\Fonts

Name=LogPixels value is 96 decimal.

For 90 percent font size, set to 86 decimal.

For 80 percent font size, set to 76 decimal.

 

Navigate to HKEY_CURRENT_USER\Control Panel\Desktop

Name=LogPixels value is 96 decimal.

For 90 percent font size, set to 86 decimal.

For 80 percent font size, set to 76 decimal.

 

Close REGEDIT and reboot the computer.

 

3. If some text appears too small or blurry try different value or return to 96 dpi.
