1.1 Changes in the ID-number

Likely sources of interference are: Strong magnetic fields from transformers and electric motors, Relays, contactors and solenoid valves, High-frequency equipment, pulse equipment and stray magnetic fields from switch-mode power supplies, Mains leads and leads to the above equipment.
Electrical interference can be avoided by: A minimum distance between the logic unit (and its leads) and interfering equipment > 20 cm. A minimum distance between the logic unit (and its leads) and cables carrying interference signals > 10 cm. (Where signal cables and cables which carry interference signals are laid together in metallic ducting, adequate decoupling can be achieved by using a grounded separation screen) Screening according to DIN VDE 0160. Potential compensating lines- 6 mm (see earthing plan). Use of original HEIDENHAIN cables, connectors and couplings.
2.2 Heat generation and cooling
Please note that the reliability of electronic equipment is greatly reduced by continuous operation at elevated temperatures. Please make the necessary arrangements to keep within the permissible ambient temperature range. Permissible ambient temperature in operation: 0 C to 45 C The following means may be employed to ensure adequate heat removal: Provide sufficient space for air circulation. Build in a ventilator fan to circulate the air inside the control cabinet. The fan must reinforce the natural convection. It must be mounted so that the warm air is extracted from the logic unit and no pre-warmed air is blown into the unit. The warmed-up air should flow over surfaces which have good thermal conductivity to the external surroundings (e.g. sheet metal). For a closed steel housing without assisted cooling, the figure for heat conduction is 3 Watt/m of surface per C air temperature difference between inside and outside. Use of a heat exchanger with separate internal and external circulation.

2 Assembly hints

Cooling by blowing external air through the control cabinet to replace the internal air. In this case the ventilator fan must be mounted so that the warm air is extracted from the control cabinet and only filtered air can be drawn in. HEIDENHAIN advises against this method of cooling, since the function and reliability of electronic assemblies are adversely affected by contaminated air (fine dust, vapours etc.). In addition to these disadvantages, a filter which is not adequately serviced leads to a loss in cooling efficiency. Regular servicing is therefore absolutely vital.

1.10.2 Conventions

The slave axis cannot be moved independently. The nominal value displayed for the slave axis indicates the nominal value of the master axis. The PLC program must ensure that the master axis does not move until the slave axis is ready (locking, feed-rate enable). The markers for direction of traverse (M2160 ff.) and axis in motion (M2128 ff.) for the slave axis are not set. An axis cannot be master and slave at the same time. Master and slave must be linear axes. Axis error compensation (both linear and non-linear) must be entered separately for both axes. The values for rapid traverse, acceleration, software limit switches, feed-rate for passing over reference marks and manual feed-rate are confirmed from the input values of the master axis. In servo lag mode the kv factor for master and slave axis should be the same. Both axes must be either analogue or digital (TNC 425) controlled.

2 Reference marks

By setting a datum point, a definite positional value (coordinate) is assigned to each axis position for the machining of the workpiece. Since the actual-position value is established incrementally by the measuring system, this correlation between axis positions and positional values must be reestablished after every power interruption. The HEIDENHAIN linear measurement systems are therefore equipped with one or more reference marks. On passing a reference mark a signal is generated which identifies the particular position as a reference point. By passing over the reference marks after a power interruption, the relationships between the axis positions and positional values (and, at the same time, the fixed machine relationships) which were most recently determined by the datum point setting are re-established.
+Z REF value REF value 0 44.985 Workpiece datum 40 +X Workpiece Machine table Position encoder Reference mark Machine datum
Since it is often inconvenient to re-establish the reference points by traversing large distances after switching on, HEIDENHAIN recommends the use of measuring systems with distance-coded reference marks. With this kind of measuring system the absolute position is available after crossing two reference marks. Scale with distance-coded reference marks The scale graduation consists of the line grating and a reference mark track which runs parallel to it. The distances between any two consecutive reference marks are defined differently, so that the absolute position of the machine slide can be determined from this distance.
Scale with one reference mark
Scale with distance-coded reference marks
2.1 Passing over the reference marks
The reference marks for axes must be passed after switching on the control. This can be achieved by
pressing the external START key. The axis sequence is determined by machine parameter

MP1340.X (automatic passing of the reference marks),
pressing the external axis direction keys. The sequence is determined by the operator.
Only after passing over the reference mark
can the software limits be activated, can the most recently set datum point be reproduced, is PLC positioning and positioning with the miscellaneous functions M91 and M92 possible, is the counter value set to zero for non-controlled axes.
For distance-coded measuring systems the machine datum (MP960.x) is reference to the ZeroReference mark. In linear measurement systems the Zero-Reference mark is the first reference mark after the start of the measuring length; in angular measurement systems the Zero-Reference mark is marked. The direction of traverse and the velocity on passing the reference marks is defined by machine parameters (MP1320, MP1330.X). The functional sequence for passing the reference marks can be fixed specifically for the axes by machine parameters (MP1350.X). The operating condition "PASS OVER REFERENCE MARKS" is sent to the PLC by the NC (W272). If the operating mode is changed before all reference marks have been passed, the Soft key "PASS OVER REFERENCE" will appear. The markers M2136 to M2140 inform the PLC for which axes the reference marks have not yet been crossed. In order to avoid exceeding the traverse range when passing over the reference marks a trip dog (reference end-position) is necessary. This trip dog must be fixed at the end of the traverse range by the manufacturer of the machine. The trigger signal from the trip dog is connected to an available PLC input. In the PLC program this PLC input is combined with the markers for "Reference endposition" (M2506, M2556 to M2559).

6.9 Files

With the TNC it is possible to process different types of file with the file management. The types of file are designated by an extension after the names.H.I.T.D.P.A.HLP.PNT = HEIDENHAIN program = DIN/ISO program = Tool table = Datum table = Pallet table = Text file = Help file = Point table
The file name can be up to 16 characters long (letters and digits). The maximum length of the file name is defined in MP7222. MP7222 Length of file names Entry: 0 to = 8 characters 1 = 12 characters 2 = 16 characters
6.9.1 File types disable and protect
The individual types of file can be selectively disabled and protected. Only file types which are not disabled are visible to the file management in the control. If a file type is locked, all files of this type are cleared. The individual file types can also be protected so that they cannot be edited or changed. Protected files are displayed with the colours defined in MP7354.1 or MP7355.1 in the file directory.

6.9.4 Datum point for values in datum table
MP7475 is used to define whether the values in the datum table refer to the set workpiece datum or the machine datum (MP960). MP7475 Datum in datum table Entry: 0 or = Datum point is workpiece datum 1 = Datum point is machine datum

6.10 User-parameters

With the MOD-function up to 16 different machine parameters can be made accessible to the machine operator as User-parameters. The machine manufacturer determines in machine parameter MP7330.x which machine parameters are to be defined as User-parameters. If, for example, you wish to define MP5030.1 as the first user-parameter, you must enter the value 5030.01 in MP 7330.0. If a User-parameter is selected by the operator, a dialogue appears on the screen. Machine parameter MP7340.X determines which dialogue should be displayed. A line number from the PLC dialogues is defined with an entry value between 0 and 4095 (see "PLC description"). MP7330 Determination of the User-Parameters Entry range: 0 to 9999.00 (No. of the desired machine parameters). User-parameter 0 User-parameter 1. User-parameter 14 User-parameter 15 Dialogues for User-parameter Entry:0 to 4095 (line number of the PLC dialogs) Dialogue for User-parameter 0 Dialogue for User-parameter 1. Dialogue for User-parameter 14 Dialogue for User-parameter 15

9.2.1 Scanning cycles

Direct access to the position control loop of the TNC controller allows the rapid recording of measured values (3 to 5 values per second). With a programmed probe point interval of 1 mm, this produces a scanning feed rate of 180 to 300 mm/min. Three scanning cycles are used for digitizing: "Range", "Meander" and "Contour Lines". The "Range" cycle defines the cuboid scanning range and the file where the digitized data are stored. The "Meander" cycle digitizes a 3-D form meander-wise (line by line) in the pre-defined range. The "Contour Lines" cycle digitizes a 3-D form level-by-level in contour lines within a predefined range. Level-by-level digitizing is mainly used for forms with steep edges.
During meander digitizing a very flat surface may cause little movement in the probe axis. This can result in a lack of lubrication in the probe axis. MP6220 and MP6221 make it possible to lubricate the axis at the end of the lines.

MP6220

Traverse for lubricating the probe axis at end of line Entry: 0.000 to 999.999 [mm] Time after which the probe axis must be lubricated Entry: 0 to [min]

MP6221

The acquired data can be stored in the controller's program memory, on the FE 401 floppy disk unit or in a PC.

FE 401

Further particulars about scanning cycles will be found in the TNC User's Manual.
9.2.2 Response of the digitizing sequence at corners
The scanning sequence responds differently for inside and outside corners. Here the two parameters PP.INT (maximum probe point interval) and TRAVEL from the "Meander" and "Contour Lines" scanning cycles operate like a travel limiter. Depending on the values that are entered for these parameters, either the travel or the probe point interval are limited. The travel is also responsible for geometrical accuracy at the corners. The smaller the stroke, the greater the accuracy of corner resolution. If too small a stroke is defined however, it may affect clearance at acute inside corners (minimum travel = 0.1 mm). Outside Corners

PP. INT

Contour

TRAVEL

On outside corners, having probed the last point x the touch probe moves down the resultant straight line until it either makes workpiece contact again or hits one of the two limits TRAVEL y or PP.INT z. In the illustrated example TRAVEL is the limit, and the touch probe returns to the contour { in the inverse scanning direction. The new scanning direction is defined by the probed points x and {.

17.1.2 Voltage from the PLC (MP3011 = 2)
The voltage defined through the PLC module 9130 is output. See also chapter "PLC Programming".
17.1.3 Definition of the voltage via M function (MP3011 = 3)
The analogue voltage output can be defined in the positioning block with the miscellaneous functions M200 to M204. These M functions are available only if the value 3 is entered in MP3011. The M functions are executed synchronously to the positioning blocks and are effective at the beginning of the block.
Direct output of the programmed voltage: M200 V. The TNC outputs the value programmed behind M200 V. as a voltage. Entry: 0 to 9.999 [V] Duration: M200 V. is effective until a new voltage is output through M200 to M204.
Voltage varies with distance: M201 V. The TNC outputs the voltage as a function of the traversed distance. The TNC increases or decreases the voltage linearly from the active voltage to the value programmed behind M201 V. Entry: 0 to 9.999 [V] Duration: M201 V. is effective unit a new voltage is output through M200 to M204.
Voltage varies with the velocity: M202 FNR. The TNC outputs the voltage as a function of the velocity. With machine parameters MP3013.x and MP3014.x up to 3 characteristic curves are defined in a table. In the table certain analogue voltages are assigned to certain feed rates. M202 FNR. selects the characteristic curve in which the TNC finds the voltage to be output. Entry: 1 to 3 Duration: M202 FNR. is effective until a new voltage is output through M200 to M204. You can enter in the table up to four kink points per characteristic curve. The output values are interpolated linearly between the kink points. The first kink point must have the value 0. The entry values of the following kink points must increase in sequence. The TNC recognizes the beginning of a new characteristic curve from the entry value 0. Example: Velocity MP3013.MP3013.MP3013.MP3013.MP3013.MP3013.000 MP3013.MP3013.MP3013.MP3013.MP3013.MP3013.Voltage MP3014.MP3014.MP3014.2 4.5 MP3014.3 9.999 MP3014.MP3014.5 9.999 MP3014.MP3014.7 0.5 MP3014.8 1.5 MP3014.9 9.999 MP3014.MP3014.11 0

When operating a computer system (PC, Controller), a wide variety of peripherals, such as printers, external memories (floppy-disk drives; hard disks) or other computer systems, can be installed in addition the Central Processing Unit (CPU). Communication between the CPU and the peripherals is made possible by using a data interface. Communication requires facilities for transferring data to the peripherals and of course, physical connection via a transmission line. Peripheral device control and communication, via the interface, is generally the responsibility of the computer system. The computer system therefore has to meet certain requirements. The interfaces, which primarily consist of the physical links between the computer system and the peripherals, need appropriate software in order to control the transfer of information between the individual units. The relationship between hardware and software, which fully defines an interface, is illustrated by the following diagram:

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

Issue: 01.09.1995 Page 3

I. How to use this Service Manual
The service manual TNC 407/415 can be used to diagnose, locate and eliminate errors on machine tools controlled by TNC. In order to correctly judge the problems in an NC-controlled machine tool, fundamental knowledge of the machine tool and its drives, as well as their interaction with the control and the measuring systems is required. Incorrect behaviour of the machine tool can also result from improper use of the control, NCprogramming errors and incorrect or not properly optimized machine parameter. For further information in this respect please refer to the.Documentation of the Machine Tool Manufacturer.Operating Manual (HEIDENHAIN).Technical Manual (HEIDENHAIN). The manual for the machine tool manufacturer is not enclosed with every control as is the operating manual. In general, it is only supplied to the machine tool manufacturer and is updated by HEIDENHAIN, Traunreut. Therefore, it is absolutely necessary to contact the machine tool manufacturer, if errors occur that are due to a machine parameter or to the interface of the control. Support will, however, also be provided by the service department of HEIDENHAIN, Traunreut. and HEIDENHAIN agencies. Telephone numbers, addresses and telex/fax numbers can be found on the back side of the cover page and on the back side of this service manual.

8.4 Checking the Power Supply (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 1, and the fuse F 4.OA protects the remaining voltages (see block diagram, section 8.3.1). If an error occurs in the power supply (all voltages are missing), first check the +24V at the supply line and then the lowvoltage fuses. By means of the test load unit, the power supply can be checked fast and easily. For this purpose the connectors to the power supply boards must be disconnected from the power supply and connected to the test load unit. The different values can be measured at the sockets of the test load unit with a multimeter. The values and their tolerances can be seen from the table in section 8.3. If the measured values deviate distinctly from the values in the table, the power supply assembly is defective. If no test load unit is available, the voltages can be measured at the measuring points on the processor board, the CLP board or the PLC graphics board. (Measuring points: see section 8.5)
1) The voltage of +24V BE is not required for the TNC 407/415. as the VDU has its own power supply,
NOTE: Always switch off the main switch before engaging or disengaging any connectors The power supply unit does not function during free-run (basic load is required).

8.6 Power Supply of the PLC-Part
The power supply line for the internal PLC is connected to the terminal block X44 (I = +24V can be switched off, 2 = +24V cannot be switched off, 3 = OV). The OV line as well as the +24V (can be switched off) line may also be connected via connector X41 or X42 (see PLC Connection Schematic, section 8.6.21. The PLC supply voltages are protected by means of low-voltage fuses on the PLC graphics board low-voltage fuse F2.5 A 24V can be switched off low-voltage fuse F 1 A 24V cannot be switched off The power supply line for the PLC I/O board PL 400 is connected to the terminal blocks Xl2 (OV), Xl3 (+24V can be switched off) and the terminal strip X3/pin 12 (+24V cannot be switched off). See PLC Connection Schematic, section 8.6.2. There is no fuse on the PLC I/O board (electronic power limiter)

9.2 Checking the Keyboard Unit
Example: The key contacts can be measured with an ohmmeter at the flange socket X2 of the keyboard unit The measuring adaptor can also be used, if available (see section 18.31. If e.g. is pressed at the TNC operating panel, < 100 rnQ can be measured between pin 17 atid pin 20 of the flange socket X2 at the TNC operating panel with the measuring adaptor (connections 17 and 201.

19.9.1 MOS Protection

For the exchange of EPROMs MOS-protection is indispensable, as otherwise the EPROMs could be destroyed by static charge. Moreover, all data should be backed up (see section 15.1). Observe the mark on the EPROMs (do not turn them by 180); be sure not to damage any components during the exchange. Use an appropriate tool. After the software exchange, the logic unit must be marked with the new NC-software number (see section 14.1). The offset adjustment with code number should be performed as well (see section 16.5). e.g. IC drawing punch and insertion tool
