Callout Description Function8 VerticalscaleBoth an input and a visualization controlfor the units per vertical division, that is,the vertical scale of the signal. The scalevalue is shown in the same way as thevalues at the left and right cursors: with 6decimal places and in the unit shown bySignal unit.The vertical scale can be modified in 3ways:• Type in the desired scale (units pervertical division) in the field.• Use the up/down arrows on the rightof the Vertical scale and Signal unitfields.• Auto-scale the trace using the Autoscale button (modifies the verticalscaling and the offset of this channel).The up/down arrows for controlling thevertical scale always change the scalefactor by 2: clicking on the up arrow doesa “vertical zoom-in”, meaning that theVertical scale is divided by 2; likewise,clicking on the down arrow does a“vertical zoom-out” and multiplies theVertical scale by 2.9 Value at leftcursorThe left and right cursor fields show thevalues of the trace data at the 2 cursors inthe unit shown by Signal unit. The 2 fieldsare updated dynamically while dragging.The value fields show the traced values to6 decimal places.Callout Description Function10 Channeldisplay type3-state button that alters the graph visual-ization of the traced signals. The 3possible states are:• Linear interpolation• Digital interpolation• Hidden lineIn linear interpolation mode, each 2subsequent samples are connected by astraight line. This visualizes the traceddata as a continuous signal.In digital interpolation mode, the traceddata is visualized as a discrete signal: thevalue of the signal is instantly changed ateach sample and remains the same untilthe next sample.In hidden line mode, the traced data forthe channel is not visualized, although thedata is available. The icon of the channeldisplay type button changes according tothe current display type.Visualization Icons: Linear Interpolation(Left), Digital Interpolation (Middle), andHide (Right)11 Signal name The drop-down list contains all availablesignals on the device and selects thesignal to be traced on the given channel.The signals are shown in alphabeticalorder of their short names. When openingthe drop-down list and moving the mousecursor over a signal, the full name of thesignal is shown in a tooltip.Table 5.9 Legend to Illustration 5.315.7.3.4 StatusThe Scope sub-tool has 5 states:• Offline: Scope is running in offline mode. A tracecannot be initiated.• Ready: Trace is not currently running and can bestarted.• Waiting: A trace has been initiated and the Scopeis waiting for a status update from the device.• Acquiring: The device has started tracing data.• Triggered: Triggering is enabled and the triggerpoint for the trace was reached.5.7.3.5 Running a TraceThe Scope must be in state Ready in order to run a trace.Click on the Run button shown in Illustration 5.33.Operation with ISD Toolbox VLT® Integrated Servo Drive ISD® 510 System128 Danfoss A/S © 01/2017 All rights reserved.
