1-4 TNC 406/TNC 306 1/98
Integrated 4-channel storage oscilloscope
The integrated storage oscilloscope can record various values in the position control loop as well as
all PLC data. The oscilloscope is activated in MOD by a soft key. Machine adjustment has now been
greatly simplified because you no longer need any external devices. You can create oscillograms in a
connected PC by using the screen dump function of TNCremo as of version 3.00.
MP7365 added: Colors of the oscilloscope
MP 7365.0: Background $000000
MP 7365.1: Channel 1 $003F3F
MP 7365.2: Channel 2 $3F3F00
MP 7365.3: Channel 3 $003F00
MP 7365.4: Channel 4 $3F1230
MP 7365.5: Reserved
$000000
MP 7365.6: Grating $30200C
MP 7365.7: Cursor and text $3F3F3F
The various functions of the oscilloscope can be selected with the aid of soft keys. With the cursor
keys on the keyboard you can switch channels and move the screen cursor. In the setup menu you
can select the various inputs with ENT/NOENT.
Step output has been expanded
The step response time measured with the integrated oscilloscope can be edited. The control
calculates the associated value for MP1060 (acceleration) and displays it.
One further soft key (INPUT RAMP) has been added. This produces an increasing (+) or decreasing
(–) ramp on the analog input. If a channel is switched to the analog input and another to the feed
rate, it can be used to graphically display the programmed input characteristic (MPs 2010, ...2070, ...)
during an active erosion process (electrode in the air!).
New code numbers for machine commissioning
For debugging, under the code number 105296 or 415263 (like TNC 410) you will find the following
menu for machine commissioning (setup):
OFFSET COMPENSATION
OUTPUT STEP FUNCTION
(Here also you can go into the parameter list)
PLC FUNCTIONS (Trace: here also you can go into the oscilloscope)
MACHINE PARAMETER PROGRAMMING
COMPENSATION VALUE LIST
Under the code number 79513 you will find the following menu and the corresponding data outputs
on RS-232-C:
DIALOG CODE NUMBERS OUTPUT (All control dialogs and numbers)
LOGBOOK OUTPUT (Contents of log)
PROGRAM RUN DATA OUTPUT (Data from geometry module to control loop)
MACHINE PARAMETER OUTPUT (Machine parameters)
Because this is purely data output, the code number 79513 can be given to any end user.
MP1710.x removed: Position monitoring for operation with servo lag (can be deleted)
MP1710.x was removed. The control multiplies the value of the normal servo lag by 1.5 and uses
the product as limit for servo-lag monitoring (erasable error message). A value of 1.8 * servo lag
should therefore be used for MP1720.x.
