Quantum Sentinel
(Graphic servo error-level monitor and configuration programme)

Modified: 2010. március 14. vasárnap

Udpate: V1.2.1!

Quantum Sentinel is a graphic error-level display, analysing and configuration programme developed for QDSP. It contains both the graphic display for transients and the ASCII configuration terminal programme. With its aid full extent PID adjustment and contoller configuration can be realized.

After installing and starting the programme, the port number of the connected serial data-interface must be inputted (Comm X). The programme will accept only existing free port numbers.
The main screen is divided for two parts:

- On the left side the graphic oscillographcan be found, which presents the error-level as the function of time (transients).
- On the right side the text-based configuration part can be found.

Beside these a menu-line with special functions can also be found on the top.

Left-side field:

Time is assigned to the horizontal axe, while the ± error-level is assigned to the vertical one. It presents the mechanical deviation compared to that of the ideal one (which is intended by the PC) as the function of the time. „The overshot ” forming during changing direction and the true track-following on the smooth sections can be studied with its help.

The measurement is triggerable (it can be started above a given error-level). The trigger level can be given with the value of the „i” register (in absolute Encoder Step units). If the trigger-monitoring is switched on, then the transient presentaion will start at t0 position of the horizontal axe. The time scale increases from the left to the right.
Taking the mouse to the figure, the current time and error-level data on the spot of the mouse pointer can be read in the Pointer filed. With the help of the left mouse button a time marker can be set and pressing this button again the closing marker can be set. The time interval between the markers can be read in the Marked field. This makes the possibility to measure the width of the treansients (in the time).
The makers can be deleted by the right mouse button.

The LED on the top signals the status of the Tracking Error Monitor. Its colour is green, when the praphic presentation is on and red when it is off.

The software keys of the graphic presentaion are on the buttom of the screen.
The monitoring can be started by Start, and it can be stopped by Stop. To change trigger mode and to start monitoring at the same time can be realized by Trigger on and Trigger off keys (through the Fuses). The Save key will save the current transient screen in BMP file-format. By the Load key a previously saved tarnsient srceen can be loaded, and this may also be the background for the next tarnsient for comparison purposes.

By colour keys the colour of the drawing can be changed. It is worth using this feature if the next transient is going to be presented on a screen previously loaded.

Right-side field:

This is the configuration side of QDSP. The registers and fuses can be adjusted and querried through this field. 

Comm The serial communication port must be assigned in the pull-down menu.

A Detect key querries the PID frequency (time data) of QDSP and sets the display above it and the time axe of the graphic presentation.

The Registers key lists the registers and their current values.

The Special key lists the special commands and registers of DSP.

The Save key saves the content of the window in txt format.

The most buttom window is the field for inputting commands. The modifying commands can be inputted here (e.g.: n4+ENTER). Typing only an empty ENTER in the line has the same effect as the Registers key has. If the generated list does not fit to the field displaying it, a side bar will appear, by which the screen can be scrolled (it is useful to use this for the display of full configuration of QDSP and for saving it).

QDSP Special Configuration menu:

State of Fuses:

It lists the current content of the Fuses . It is the same as the 'u' command.

Thermo protection on 60°C, 80°C, 100°C:

Sets the heat-protection to 60, 80 or 100°C.

Motor protection off (Temporaly):

It temporarily makes the overload-protection of the motor inefficient (for testing purpose).

Soft limit with Fault signal:

If the Error-level exceeds the content of the Soft limit register, Fault signal will be generated in the output.

Soft limit without Fault signal:

No Fault signal will be generated if the Error-level exceeds the content of the Soft limit register.
