7 Oscilloscope
The oscilloscope function integrated in the regenerative power supply module 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 regenerative power supply module
 Documentation of production quality in the context of product liability and quality
assurance
Special features
 Recording and saving of the measured values in the regenerative power supply module
 Measuring on eight independent channels at the same time
 Measuring fast and slow signals by adjustable sample rate
 Triggering on channel, variable, or error message
 Detecting 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
 Exporting measured values via the clipboard for further processing
