Disable Feed and Speed override potentiometers - Heidenhain

[doubravacek]

Hi,

I need to disable feed and spindle override potentiometers in my OEM cycle for tapping.
Or code of cycle 17. It has this feature..
Control: Heindenhain 426

Any solutions please?

or do you know how to write to PLC (address W764)?
it sets override to 100%
