13 Oscilloscope
The oscilloscope function integrated in the controller can be used as support for commissioning,
maintenance, and troubleshooting.
Typical applications
• Graphical representation of any measured values (e.g. speed setpoint, actual speed, and torque)
• Detection of process values without additional measuring instruments (e.g. oscilloscope,
voltmeter and ammeter)
• Convenient documentation for fine tuning of control circuits or parameter changes of the
controller
• Documentation of production quality in the context of product liability and quality assurance
Special features
• Recording and saving measured values in the controller
• Simultaneous measuring on eight independent channels
• Measuring of fast and slow signals by means of adjustable sample rate
• Triggering on channel, variable, or error message
• Detecting of measured values before and after a trigger event (pre-/post-trigger)
• Graphical representation and evaluation of measured values on a PC
• Cursor and zoom function for the measurement analysis
• Saving & loading of oscilloscope configurations
• Export of measured values via the clipboard for further processing
13.1 Technical data
13.2 Functional description
With an online connection to the controller, use the oscilloscope user interface of »Engineer« to set
the trigger condition and the sample rate and select the variables to be recorded.
