Setup  Activate the oscilloscipe by entering the code number 688379 --> the setup menu is displayed.
 Choose the parameters to be entered with the cursor keys.
 Press GOTO --> a popup window is displayed.
Output:
 Select whether the nominal speed value is to be issued as a step or ramp:
Feed rate:
 Enter the height of the step for the nominal velocity value (in mm/min).
This entry has no effect for ramp output.
17 – 246
If you select ramp output, then the programmed feed rate, k
values that you have specified with machine parameters go into effect.
If you select step output, a step will be output as nominal velocity value when you press
the axis-direction buttons in the Manual operating mode. During output, the position control
loop is open.
With this recording mode you can e.g. find out, whether machine vibrations (after replace-
ment of mechanical components) are already generated in the current or speed controller,
or whether they derive from the position controller.
DANGER
When operating the oscilloscope with step output (= traverse without position control
loop) you may damage your machine or even cause injury to persons!
The specified feed rate is the step height.
Start recording with a small step which you can increase if necessary.
Set the feed rate to zero before terminating the oscilloscope function.
When the internal oscilloscope is activated again, "Ramp" output is automatically selected.
