The oscilloscope provides additional functions for commissioning the current

controller. (See "Commissioning" on page 6 – 462).

The recorded data remain stored until you start recording again or activate

another graphic function.

In MP7365.x, define the colors for the oscilloscope.

Activate the oscilloscope with the code number 688379.

After you enter the code number, the setup menu appears:

Choose the parameters to be entered with the cursor keys.

Select whether the nominal speed value is to be issued as a step or ramp.

• If you select ramp output, then the programmed feed rate, k

acceleration 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 opened.

Enter the height of the step for the nominal velocity value (in mm/min). This

entry has no effect for ramp output.

Sample time:

Set the time interval for recording the signals: 0.6 to 6 ms. 4096 samples are

stored. The signals are therefore stored for a duration of 2.4576 to 24.576

Channel 1 to channel 4:

Assign the channels of the recorded signals to the respective axes.
