7.5 Checking and Changing Q Parameters

Q parameters can be checked and – if necessary – changed during a
program run or program test.

Preparation:

• If you are in a program run, interrupt it, for example by pressing the

machine STOP key and the INTERNAL STOP soft key.

• If you are doing a test run, interrupt it.

To call the Q parameter:

Q

Select the Q parameter, for example Q10.

Q10 = + 100

The TNC displays the current value, for example Q10 = 100.

Change the Q parameter, for example Q10 = 0.

Leave the Q parameter unchanged.
