PLEASE NOTE: 8
You cannot access the “Select PWM mode”, “Start FFT” and “Start plot” menus until you have
recorded a positioning movement. 8
8.4.3.3 Sending the positioning movement to the oscilloscope (“Select PWM mode” menu)
You can send the positioning movement as a pulse width-modulated signal to an oscilloscope for
further analysis. The PW0 … PW3 outputs are permanently assigned to panels BNC1 ... BNC4,
i.e. if you wish to display the signal for the X1 axis (top axis controller in the module), the previous
assignment of BNC1 is overwritten with the assignment to the PWM0 signal. If you wish to retain
the old assignment, then you must reconfigure M1VSOLL (see section 6.2
“Configuration” menu
on page 54
).
Æ Select the “Select PWM mode” option from the “Proceeding” menu. The “Select PWM mode”
menu appears.
Fig. 8 - 28 “Select PWM mode” menu
“Static” PWM mode
If you select this mode, the positioning movement is recorded once after the falling edge of the
trigger signal, and is then output. If there is no trigger signal, then the positioning movement is
output from the falling edge of the end signal.
“Dynamic” PWM mode
If you select this mode, the positioning movement is recorded and output to the oscilloscope
continuously from the falling edge of the trigger signal or end signal.
Returns to the “Proceeding” menu
PWM mode: Static
PWM mode: Dynamic

Use the and cursor keys to select the parameters.
Use the and cursor keys to increase or reduce numerical values or select the
trigger signal.
8.4.3.4 Analyzing the positioning movement using FFT (“Start FFT” menu)
To provide further details for the analysis, we plan to output the positioning movement as a spec-
trum using the FFT.
8.4.3.5 Outputting to a plotter (“Start plot” menu)
Æ Select “Start plot” and press .
The window for selecting the time range appears.

Æ Press to confirm your settings.
Æ Set marker T2 as described for marker 1.
Æ Select "Quit". The numerical value of the time window is output to the plotter.
8.4.4 “Track signal” menu
This menu is designed to help you analyze and troubleshoot track signals.
Æ Select the “Track signals” option from the “Properties” menu (see Fig. 8 - 23 on page 69).
The following window appears.

8.4.4.1 Checking track signals for zero pulse errors
Æ Select the “Reference error” menu option.
The window for starting the measurement appears.
Fig. 8 - 33 Starting the measurement to identify zero pulse errors
Æ Turn the axis either manually or using the SITEST program. Then return it to the starting point
and stop the measurement.
