The power for the PA 110 can be supplied according to VDE 0550, provided that the analog inputs and connections for the Pt 100 are shockproof according to VDE 0160 (Section 5.5.1). If this is not possible, the entire PLC power supply and the power for the PA 110 must be provided according to VDE 0551.

4.1.3 Buffer battery

The buffer battery is the potential source for the RAM memory for NC-programs, PLC-programs and machine parameters when the control is switched off. If the EXCHANGE BUFFER BATTERY message appears, the batteries must be exchanged. The 3 batteries may be found behind a screw cap in the power supply section of the logic unit. As well as the batteries, the logic unit contains an additional energy store, mounted on the processor board, for buffering the memory contents. This means that the mains can be switched off when replacing the batteries. The energy store will ensure that the memory is retained while the batteries are exchanged.

MP7460

This machine parameter is effective for operation with feedforward control as well as for operation with lag. The permissible size of the angle depends on the drives in the machine. Realistic values are 5 to 15.
The resulting path is as follows:
Axis standstill = Change of axis direction sa = Servo lag
Path when MP7460 < Path when MP7460 >
Constant feed rate in corners Entry value: 0.0001 to 179.9999
3.4.3 Constant feed rate in corners with M90
The miscellaneous function M90 was introduced to enable constant surface speed to be achieved in corners without radius compensation. This miscellaneous function is only effective in operation with lag!

sa without M90

with M90
3.4.4 Contour speed related to tool cutting edge
The programmed feed-rate normally relates to the path of the cutter centre. When M function M109 is active the feed-rate at radii is increased or reduced to maintain a constant feed-rate at the cutting edge of the tool. When M function M110 is active the feed-rate is reduced only. There is no increase in feed-rate. When M function M111 is active the programmed feed-rate is re-assigned to the path of the cutter centre.
3.4.5 Preset tolerance at corners
3D forms are often described by a progression of very short linear blocks. The control reduces the feed rate at the discontinuous transitions in order to keep the tool exactly on path. If you are working with servo lag, depending on the feed rate the corners will be more or less "rounded" if M90 is entered or if MP7460 is set correspondingly. Since feedforward control is intended to virtually eliminate servo lag, working with feedforward control will result in sharp corners. This is not desired, however, on 3D forms. With the M function M112 you can enter a tolerance for the deviation from the programmed contour at corners and a limit angle for activation of the tolerance.
A rounding arc is inserted at corners. The radius of the arc is a function of the entered tolerance T and the limit angle A. Three radii are calculated: r1 = T= b= = v= a=

15.2.1 Output of tool number (fixed pocket coding)
Evaluating the tool number is adequate for fixed tool pocket coding. MP7480 is used to select whether the tool number should be transferred to the PLC with every TOOL CALL (TOOL DEF) block or only when the tool number changes (input values for MP7480 = 2 or 1). With this setting the tool number is transferred to the word W262 when a TOOL CALL or TOOL DEF block is executed. W264 is not used. If MP7261 > 0, then pocket numbers are displayed in the pocket table. Entering 5 or 6 in MP7480.0 transfers the pocket number to W262 and the tool number to W264. Unlike the setting with variable pocket coding (MP7480 = 3 or 4) the assignment of tool and pocket numbers in the pocket table does not change.
15.2.2 Output of pocket number (variable pocket coding)
With variable pocket coding, the NC must transfer the pocket number of the called tool to the PLC (MP7480 = 3 or 4). In this setting, the pocket number is filed in word W262. In addition to the pocket number, the NC also transfers the current tool number in W264. Variable pocket management (the assignment of tool number to pocket number in the tool table) is handled by the NC. The PLC can use marker M2612 to tell the NC that the pocket number in the tool table should not be updated during "Block scan". The number of tools with a pocket number is defined in machine parameter MP7261. The input value for MP7261 matches the number of pockets in the tool magazine. This means that more tools can be defined in the tool table than there is room for in the tool magazine [(MP7260) > (MP7261)]. If a tool number is programmed and no pocket is defined for it, pocket number 255 (W262) is transferred on TOOL CALL, and marker M2402 is set. Only the tool number and the pocket number are transferred when TOOL DEF is programmed. A TOOL DEF for a manual tool has no relevance in the PLC. A fixed pocket can be defined in the field ' F' of the pocket table. Tools for which a fixed pocket is defined are returned to the same pocket despite variable coding.

The datum tables, pallet tables and text files are to be disabled. Input value for MP7224.0 = Binary %Hexadecimal $ 38 Decimal 56 (23 + 24 + 25) With software types 243 05, 259 96, and only the decimal format is possible for the machine parameters. The corresponding decimal input value must be computed for bit-coded entries. You will find a "Power of 2" table in the chapter entitled "Appendix".
2.2 Activating the machine parameter settings
After the values for the machine have been entered, exit the machine parameter list by pressing the END - key. Missing or incorrect entries result in error messages from the control that prompt you to correct your entry. The following errors are displayed: Entry error 6 Meaning No MP number found Invalid MP number No separator ";" found Entry value incorrect MP doubly defined MP not defined MP can not be stored
If the control does not recognise any errors, it automatically exits the machine parameter editor and is ready for operation. If during commissioning no entries are made in the parameter list (MP NAME), the TNC will generate a standard machine parameter list when the END key is pressed. In this list the TNC is defined as a programming station with the HEIDENHAIN standard colours. All other machine parameters assume the minimum value. It is also possible to keep several machine parameter lists and load the desired list into the TNC when needed. The desired list can be selected in the machine parameter editor by pressing the PGM NAME key and the SELECT soft key. The parameter list which is active when you exit the machine parameter editor goes into effect.
2.3 Changing the entry values
After a machine parameter list has been created, it can be changed either through the machine parameter editor or directly through the PLC.

2.3.1 Manual input

Call the machine parameter editor through the MOD function "code number". Enter the code number to access the complete list of machine parameters. Entering the code number 123 opens a partial list of machine parameters. These are the machine parameters that may be changed by the control user (see User's Manual for TNC 407/TNC 415). The machine parameters which can be changed with the code number 123 are marked in the following list with CN 123. Exit the machine parameter editor by pressing the END key.
2.3.2 Changing the entry values via PLC
The entry values of the active machine parameter list can be changed with the module 9031 (see chapter "PLC Programming", section "PLC-modules"). These changes are then erased when the TNC is switched off. The machine parameters which can by changed through the PLC are marked in the following list with PLC EDIT or PLC RUN. PLC EDIT means that the machine parameters can only be changed if no program is being executed on the machine. PLC RUN means that the machine parameter can be changed even while a program is being executed.

4.2.2 Read Machine Parameter (Module 9032)
Reads the value of a machine parameter that is defined by its number and index from the editable machine parameter list. Constraints: - The value of the machine parameter is returned as an integer, with the decimal point being shifted by the number of possible places after the decimal. Example MP910.0 = 100.12 mm is read as 1001200 (four places after the decimal lead to a multiplication by 10000). - Only the value from the editable machine parameter list is read, not any value in the run-time memory modified by PLC Module 9031. - Zero must be given as the index for non-indexed machine parameters. Possible errors: - The machine parameter specified by the MP number and index does not exist. - The module was not called from a Submit Job. Call: PS PS CM PL B/W/D/K B/W/D/K 9032 B/W/D <MP Number> <MP Index> <MP value> / <Error Code> 1: No such MP number 2: No separator 3: MP value out of range 4: MP not in file 5: No MP file found 6: Call was not from SUBMIT Job 0: MP was read 1: Error condition see above
4.2.3 Select Machine Parameter File (Module 9033)
The machine parameter file with the specified name is selected (M status assigned) and a control reset is executed if another file was previously selected. Constraints: - The module can only be called from a SUBMIT Job. - The module disregards any safety problems when initiating the control reset (e.g. free run-out of axes and spindle). - The module can only be used on files in the RAM. - The new MP file to be selected is checked, a faulty file is not selected. - There is no return to the calling PLC program if file selection is successful. - The file name is specified in a string that must contain the file name with extension. Additional characters (including blanks) are not allowed. - If the PLC program is created externally ensure that lower-case letters are not used for the file name. - Once the NC program has started the module only operates during the output of M/G/S/T/T2/Q strobes.
Possible errors: - The module was not called from a SUBMIT Job. - The specified string does not conform to the above conventions. - There is no file with the specified name. - The file to be selected is faulty. - The module was called after the NC program started without a strobe marker being active. - An incorrect string number was specified (out of range 0.3) Call: PS CM B/W/D/K 9033 <String Number> Warning: Program execution ends here if a new file is selected <Error Code> 0: No error, file was already selected 1: String contains no valid file name 2: File not found 3: File is faulty 4: Wrong string number specified (0.3) 5: Call was not from a SUBMIT Job 6: Call once PGM started without strobe
0: File was already selected 1: Error condition see above

3.4 Oscilloscope

An oscilloscope has been integrated in the TNC 407/TNC 415 B/TNC 425 for trimming and optimizing the speed and position controllers. The characteristic curves which the oscilloscope records can be stored in 4 channels and for all axis. The following curves can be displayed: Feed rate Position and trailing error V ACTUAL V NOMINAL S ACTUAL S NOMINAL D DIFF N ACTUAL N NOMINAL N INT U ANALOGUE Actual value [mm/min] Nominal value [mm/min] [mm] [mm] Trailing error for position control [mm] Actual speed [mm/min] Nominal speed [mm/min] Nominal/actual difference for speed controller Analogue voltage [mV]
Speed (digital speed control only) Nominal value
Note on speed curves Rotational speeds are recorded as feed rates in mm/min. The speed in rpm. can be calculated with the help of the distance covered per revolution, i.e. Rotational speed (rpm) = Feed rate [mm / min]

Traverse per rev. [ mm]

The data recorded for the display are stored until an NC graphic is called. Likewise a computed graphic simulation is deleted by the oscilloscope display. A total of 5 colours can be selected in machine parameters for the oscilloscope display. They are selected in exactly the same way as the 3-plane view in NC graphic simulation. MP7361.0 MP7261.1 MP7361.2 MP7361.3 MP7361.4 Background Grid Non-selected channels Cursor line, data, screen window Selected channel
The "Oscilloscope" mode is entered by keying in code number 688 379. If you leave the Oscilloscope mode you can re-enter it using the MOD key and the OSZI soft key. The code number must only be re-keyed when the supply voltage has been switched off. The following main display appears when the mode is called:
Use the cursor keys to move the highlight (cursor) to the desired item and to select the trigger conditions and the axes and parameters you wish to record.

3.4.1 Soft-key rows

Meaning of soft keys:
Start recording Vertical zoom Horizontal zoom Optimal vertical resolution, centred in screen

Activate cursor

3.4.2 Triggers
The following entries are possible:
FREE RUN Recording is terminated manually SINGLE SHOT Records a memory content - initiated by trigger condition. CHANNEL. Starts recording when the trigger threshold of the selected channel is exceeded.
Trigger threshold The trigger threshold for the selected channel is entered as a numerical value in the following units:
Linear speed [mm/min] Position [mm] Rotational speed [mm/min] Trailing error [m] Analogue voltage [mV]
Edge Triggering with rising (positive) and falling (negative) edge. Pre-Trigger Defines the start of the recording as a % of the total recording time; possible entries are 0%, 25%, 50%, 75% and 100%. Press the ENT key to select.

3.4.3 Recording

The recording parameters to be edited are selected with the arrow keys. The values for FEED RATE and TRIGGER THRESHOLD are entered with the numerical keys. The values for all other recording parameters are selected by pressing the ENT key. Output In the Manual mode you can choose between the set ramp and a step function for outputting a nominal value. The step function is only possible with digitally controlled axes and is necessary for trimming the speed controller. The step function and the oscilloscope recording facility can also be used to determine the maximum acceleration of the machine when the provisional input value is not known. In the MDI or Automatic modes acceleration is always by the set ramp.
Feed rate With a step function as the output signal, the feed rate is entered in [mm/min]. The programmed feed rate dictates the acceleration after the ramp.
Time resolution The recording time ranges from 2.4576 sec. to 24.576 sec. (set time x4096). The time set between 0.6 and 6 ms is the cycle time for recording curves. The recording time is overlaid beneath the grid. The beginning and end of the image are also displayed relative to the trigger point (cursor line T1).
Channels 1 to 4 A total of 4 channels can be selected for recording. The axes can be randomly assigned to the channels - this is done using the ENT key after selecting the entry position. For each channel a characteristic curve is selected from the following variables: Feed rate Speed Speed controller Position Trailing error Analogue voltage Channel V ACTUAL V NOMINAL S ACTUAL S NOMINAL N INT N ACTUAL N NOMINAL D DIFF U ANALOGUE OFF SAVED Actual value [mm/min] Nominal value [mm/min] Actual value [mm] Nominal value [mm] Nominal/actual difference for speed controller [mm/min] Actual value [mm/min] Nominal value [mm/min] Trailing error for speed control [mm] output analogue voltage [mV] Channel is displayed Channel is saved
Recording is activated with START (soft key). This calls a soft-key row in which the sole option is STOP. Recording can be interrupted at will. Saved channels cannot be displayed at the same time as recording is in progress because synchronization between the saved channels and the channels currently recording is not possible.

10.3 Checking the Power Supply Unit
Two low-voltage fuses are located on the POWER SUPPLY assembly. The fuse F 2.5A protects the output voltage of +24V BE (not required for TNC 415B/425), and the fuse F 4.0A protects the remaining voltages (see block diagram in section 10.2.1). If an error occurs in the power supply (all voltages missing), first check the +24V at the supply line (2-pin terminal strip X31) and then the low-voltage fuse F 4.0A. The voltages can be measured directly on the power supply board, the processor board and the CLP board (sections 10.3.1 and 10.3.2). The values and their tolerances can be seen from the corresponding tables. If the measured values deviate distinctly from the values in the table, the power supply assembly is defective.
Observe the safety instructions!
The power supply unit does not work without load. (Basic load is required)

Machine Parameters

In the following list the machine parameters for all software versions are listed. Since however, certain machine parameters are only valid for a certain software version, or are only active from a certain software version on, columns with symbols for differentiation have been introduced after the machine parameter number.
Explanation of the Symbols:
04 I04 = The machine parameter applies for all software versions of this control. = The machine parameter has been introduced with a certain software version (e.g. 04 means: introduced with software version 04). = The machine parameter is inactive. = The machine parameter is not available with this control.

User Parameters By means of the MOD function "User Parameters" certain machine parameters can be altered easily (e.g. adaptation of the data interface). The user parameters that are accessible via this MOD function are determined in machine parameters by the machine tool manufacturer. 0-1900 Input Values Input values are e.g. - the numbers 0 and 1 to select functions, algebraic signs or the counting direction or - numerical values for feed rates, displacement etc. - decimal input values that can be calculated by combining several functions (bitcoded) - bit patterns (selectable with %) e.g. MP 10 : % 00111 i.e. X,Y,Z with encoder (1) IV, V without encoder (0) - hexadecimal values (selectable with $) e.g. MP 7353.0: $ 0F818A7350 Structure The machine parameters are subdivided into groups. The parameter numbers are structured such that the list can be expanded easily. 7600 Encoders and machine tool axes: allocation, evaluation, compensation Positioning Operation with feed precontrol Operation with servo lag Integral digital speed control (TNC 425) Integral speed and current control (TNC 426 PA) Spindle Integral PLC Adaptation of the data interface 3D-touch probe (general parameters) Connection of measuring touch probe or touch trigger probe Digitizing with 3D-touch probe Tool calibration with TT 110 Tapping Display and programming User parameters Colours, general display and FK graphics Operation and program run Tilting the working plane Hardware
