Drive Curve

 

The curves are quasi real time online representations of the operating status (depending on the speed of your computer).

 

At the bottom left you can select which data are to be displayed.

 

 

If analogue and digital values are displayed at the same time, the curves are displayed at the top and the digital signals are displayed at the bottom.

To move the separating bar between the analogue and digital values, proceed as follows:

 

§ move the mouse to the bar

§ Press left mouse button

§ keep the left mouse button pressed and move the bar to the required position

§ Release the button

 

 

If not all digital signals can be displayed on the screen, only a part of them is displayed. Use the scroll bar on the left side to scroll through the list of signals.

 

 

 

If you right-click in the analogue field, a cursor bar is set. The analogue values at this cursor position are displayed at the top in the scaling axis.

The cursor bar can be moved to any position. Right-click on it and drag it to the required position.

 

You can also have a closer look on certain curve sections by "zooming into" the curve.

To do this, press the left mouse button in the travel curve window, keep it pressed and drag a square across the required curve section. When you release the mouse button, this curve section will be enlarged.

The current values are displayed on the axes (left and top).

 

At the bottom right, you will find a zoom overview. This indicates the current position in the travel curve.

Zooming is also possible in the case of the digital signals. To close the zoom window, press the "ESC" key.

 

It is possible to switch between an absolute value representation and a representation with sign (positive / negative). To switch over simply click on the button "pos./neg." or "Amount".

If you select positive-negative representation, the speed will be positive during upward movements and negative during downward movements. In this setting it is possible, for example, to distinguish between counterrotation and normal rotation of the pulley on the travel curve.

 

If you click on the button "Menu", you can edit parameters without closing the travel curve window.

 

 

Use the right button "<->" to open and close a special menu window. In this window. the travels are listed, indicating the date and time. The last 150 travel operations viewed with the PowerControl software are stored. If you click on one travel, it will be displayed on the screen immediately.

 

With new devices also the travel counter is shown in parentheses:

Saving travel curves

As a standard, the last 150 travel operations viewed with PowerControl32 are stored temporarily. If more than 150 travel operations are carried out, the oldest travel will be deleted. To save one of these travel operations permanently, proceed as follows:

 

·         Open the travel curve window ("Display" ð "Drive curve")

·         Click on right button "<->". A special menu window will be opened. In this window. the online travels last viewed are listed, indicating the date and time.

·         Click on the required travel. This will be displayed on the screen.

·         In the white field below the travels, you can enter a text relating to the curve. Here, you can save more details of the travel operation.

·         Click on button "Save curve ".

·         In the window now opened, select a file name and confirm it.

 

The "Data" path will be used as a standard. If you select another path, this path will be saved and used as the default path when the program is started the next time.

 

Travel curves from USB stick

There is a possibility to record travel curves from the VVVF on a USB stick (USB host option PCB necessarily). These travel curves also can be displayed and saved with the PowerControl32 software.

The selection takes place via clicking one of the upper buttons:

·         Button "HD": last stored travel curves of the hard disc are listed. This also is the standard attitude when open the travel curve window.

·         Button "USB": travel curves of the USB stick are listed

 

If several USB sticks with RST drive curve data are present, then a selection window of the drive discs appears. Select the suitable drive disc and confirm with "OK".

 

The file name is assigned automatically by the USB host with a sequential numbering. On the right side of the file name in the travels listing the travel counter is displayed. Thereby a direct allocation to error registrations can take place in the error memory.

 

The USB host option PCB stores the travel curve data in principle in the folder "RST_DATA.USB". The name of the folder may not be renamed and must be located in the main path.

If the data are copied on the hard disk, then the complete folder must be copied in the main folder, e.g.:

C: \ RST_DATA.USB
