1 Hardware concept

The HEIDENHAIN-contouring controls TNC 407 and TNC 415 are designed for use with drilling and milling machines.

The HEIDENHAIN-TNCs consist of several units. The principal subassembly is the logic unit. The logic unit is joined to the other units and the TNC accessories by connecting cables.

PLC outputs

The logic unit contains the electronics for both the NC and the PLC sections of the control. The common data area contains the machine parameters and the PLC markers and words. The machine parameters define the hardware configuration of the machine (ranges of travel, acceleration, number of axes etc.). The PLC markers and words are used for the exchange of information between the NC and the PLC.

3 Software

The logic unit contains separate software for the NC section and the PLC section. The software is identified by an 8-figure number.

After switching on the control, the NC, PLC and Software-Options software numbers are displayed on the screen. The software number can also be directly requested with the aid of the MOD function.

3.1 NC-Software

3.1.1 NC-Software number

The 8-figure NC software number identifies the type of control, the dialog language (language of the country) and the version of the software.

259 96 0 01

Software type

National language

0 = German 1 = Czech 2 = French 3 = Italian 4 = Spanish 6 = Swedish 7 = Danish 8 = Finnish 9 = Dutch

Software version

In addition to the above-listed languages, the TNC can always use English, which may be selected via the machine parameter MP7230.

3.1.2 Software types

Due to restrictions on the export of the TNC 415 B, HEIDENHAIN can also deliver a special export version. This export version is differentiated from the standard control through the installed software type. With this software type, the control offers different features in respect of linear interpolation and the entry/display resolutions.

Linear interpolation Entry/Display

Resolution

TNC 415 B (Standard) 5 of 5 axes up to 0.1 µm TNC 415 F (Export) 4 of 5 axes up to 1 µm

The TNC 407 does not fall under the export restrictions, therefore no export version is necessary.

01.98 TNC 407/TNC 415/TNC 425 3 Software 2-7

New functions will be introduced only in the following software types:

TNC 415B / TNC 425: 280 54 TNC 415F / TNC 425 E: 280 56 TNC 407: 280 58

These software types are therefore supplied as standard.

3.1.3 Software option

HEIDENHAIN offers the "Digitising with TS 120" function as a software option (see chapter "Machine integration"). An additional software protection module is installed in controls supplied with this software option. The Id.-Nr. of the logic unit indicates another version. If the software module is installed, the option is indicated on the screen under the NC and PLC software numbers.

Logic units that have already been delivered can be retrofitted with the software protection module. Please contact HEIDENHAIN if you wish to buy this option for your existing control. The proper component model must be ordered for a specific hardware model.

3.2 PLC-Software

The PLC software is produced by the manufacturer of the machine. Either HEIDENHAIN or the manufacturer of the machine can store this software in EPROMs. HEIDENHAIN assigns PLC software numbers to the machine manufacturers on request. HEIDENHAIN can archive the specific PLC programs in a data bank, so that the installation of the correct PLC program is assured if a control has to be exchanged.

The PLC EPROM must be written in the format of the corresponding software type! Beginning with software types 280 54, 280 56 and 280 58, either a 1 MB or a 2 MB EPROM can be used for the PLC.

3.4 Software replacement

Before replacing the software on a TNC the data of all file types, the machine parameter list, the nonlinear axis error compensation table and the PLC program (if in the RAM) must be backed up.

You can use the TNC BACKUP routine to do this. In the "Machine Parameter Editor" mode (code number 95 148) press the MOD key to display the menu for configuring the data interface. The "BACKUP DATA" and "RESTORE DATA" soft keys will be offered.

Use "BACKUP DATA" to transmit all operating parameters and the data of all file types across the data interface and store them in the $BACKUP.ANC file. When software replacement is complete, use "RESTORE DATA" to download the data to the TNC again.

The offset for a variable-speed spindle is now adjusted with a new algorithm. A single offset

−

adjustment is made two seconds after the nominal value has reached target position. Every second thereafter the offset voltage is increased by 0.152 mV or decreased by 0.152 mV when servo lag is greater or less than zero respectively, and if the voltage computed from the product of servo lag and Kv factor is greater than 0.152 mV. This means that the offset voltage changes by 1 mV in 7 seconds approx.

New functions:

– A “PLC” column was added to the tool table. As in the pocket table, relevant PLC data can be

entered here. This column is activated with machine parameter MP7266.17. – A datum, tool, or pocket table can be searched for to certain values using Module 9092. – The PLC can activate the geometry data of the tool from W264 with the new marker M2717. – The elements “Number of cutting edges“, ”Tolerance for tool length”, “Tolerance for tool

radius”, “Cutting direction of the tool” and “PLC status” were added to Modules 9093 and 9094. – During feed pre-control, the positioning window is not evaluated until the current velocity is less

than MP1525. In the previous software versions, the positioning window was not evaluated until

the velocity fell below 0.5 mm/min. Increasing the input value in MP1525 increases the block

processing time. – Feed pre-control can be activated for all modes of operation with machine parameter MP1391.

This becomes necessary when stiction compensation is to be active in the manual modes of

operation. – The maximum permissible positional difference between the two gantry axes is defined in

MP855. When this value is exceeded, the blinking error message GROSS POSITIONING ERROR

<AXIS> # A appears. The current positional deviation appears in the LAG display of the slave

axis. – Module 9171 makes it possible to orient the spindle at a rotational speed defined by the PLC. – Modules 9040 and 9041 make it possible to read coordinates referenced to a shifted coordinate

system. – The jog increment can now be limited with Module 9036. – With the new marker M2827 an EMERGENCY STOP (control-is-ready PLC input signal) can be

suppressed and, instead, all control loops opened and an NC stop executed. – The new marker M2830 opens all control loops and stops the NC. – In a digitized data file that has been produced with the TM 110 touch probe, the BLK FORM is

enlarged in the working plane by double the value of the deflection depth (MP6310). – The radius compensation in the working plane is now also effective in NC blocks with 5-axis

interpolation. The NC block can contain, besides the three non-parallel linear axes, also two rotary

axes. – Tool measurement with the TT 110 is possible only on machines with controlled spindle

(Spindle orientation).

New functions:

− To make changes to the tool table it is no longer necessary to transfer the entire tool table. It now

suffices to transfer only those tool data that have changed. These partial data can be transferred in the Program Run mode of operation

− For a rotary table display that is set to modulo 360°, the M function M 126 positions the table by

the shortest path. M 127 positions the table, as before, by the path that does not cross over the 0° position.

The function for automatic tool measurement was expanded with the TT 110. The new fields L-OFFS, R-OFFS, LBREAK and RBREAK were introduced to the tool table (MP7266.19 to MP7266.21). In addition, in Cycle 31 the radius is no longer entered and the fields L-OFFS, R-OFFS, LBREAK and RBREAK were added to the modules 9092, 9093 and 9094. The new marker M2393 is set whenever the break tolerance is exceeded.

2 Assembly hints

2.1 Electrical noise immunity

Please note that the vulnerability of electronic equipment to noise increases with faster signal processing and higher sensitivity. Please protect your equipment by observing the following rules and recommendations.

Noise voltages are mainly produced and transmitted by capacitive and inductive coupling. Electrical noise can be picked up by the inputs and outputs to the equipment, and the cabling.

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 mm² (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/m²

of surface per °C air temperature difference between inside and outside.

– Use of a heat exchanger with separate internal and external circulation.

01.98 TNC 407/TNC 415/TNC 425 2 Assembly hints 3-9

– 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.

2.3 Humidity

Permissible humidity: < 75 % in continuous operation,

< 95 % for not more than 30 days p.a. (randomly distributed).

In tropical areas it is recommended that the TNC is not switched off, so that condensation is avoided on the circuit boards. The heat generation prevents condensation and has no further disadvantages.

2.4 Mechanical vibration

Permissible vibration: < 0.5 g

2.5 Mounting position

Note the following fundamental points on mounting:

- mechanical accessibility,

- permissible environmental conditions,

- electrical noise immunity,

- the electrical regulations which are in force in your country.

2.5.2 Visual display unit (VDU)

When mounting the VDU it must be remembered that this unit is very sensitive to magnetic pick-up. The picture position and geometry can be disturbed by stray magnetic fields. Alternating fields cause periodic movement or distortion of the picture.

For this reason, keep a minimum distance of 0.5 m between the VDU casing and the source of any disturbance (e.g. permanent magnets, motors, transformers etc.)

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.

5 Measuring systems

The HEIDENHAIN-contouring controls are designed for the installation of incremental linear and angular measuring systems.

The control controls the actual position with a measuring step of 0.0001 mm or 0.0001°. Measuring systems and encoders with a graduation period of 0.001 mm or 0,001° to 0.1 mm or 0.1° may be used.

It does not matter whether the measuring system or encoder has one or several reference marks. However, HEIDENHAIN recommends the use of measuring systems with distance-coded reference marks, since the traversing distance when referencing is thereby reduced to a minimum. See Chapter "Machine Integration".

The current requirement per measuring system input must not exceed 300 mA. The maximum current requirement for all measuring system inputs together is limited to 1.2 A.

5.1 Linear measuring systems

Measurement of length is best performed by a linear measuring system or encoder. Insofar as it is compatible with the accuracy requirements, linear measurement can also be made using a rotary encoder on the ballscrew.

HEIDENHAIN recommends use of the following linear measuring systems:

LS 103 C, LS 106 C, LS 405 C, LS 406 C, LS 706 C, LB 326, ULS 300 C.

For linear measurement with the aid of a rotary encoder and a ballscrew you could use, for example, an ROD 450.

5.2 Angular measuring systems

For direct angular measurement in the A, B or C axes the following incremental angular measuring systems are available: ROD 250 C, ROD 700 C, RON 255 C, and RON 705 C.

In order to meet accuracy requirements, HEIDENHAIN recommends line counts of at least 18 000.

5.4.2 Connecting cable

Please use only HEIDENHAIN-measuring system cables, connectors and couplings.

In order to be able to connect a measuring system to the square-wave signal input of the logic unit, the sinusoidal signal from the measuring system must be converted to a square-wave signal. This conversion is performed by the interpolation and digitizing electronics (EXE). The interpolation and digitizing electronics is either integrated into the measuring system or made as an independent unit.

If the interpolation and digitizing electronics does not have its own power supply, it can be supplied from the logic unit. In order to ensure a correct supply voltage, the total length of the connecting cable between the interpolation and digitizing electronics and the logic unit must be limited (see the following diagram).

10 Push the connector together.

The following points must be observed when assembling the measuring system:

.The inner screen (pin 9) must not make any electrical connection with the outer screen (connector housing). .The outer screen of the measuring system cable must have an electrical connection with the connector housing. .The measuring system is grounded through its mechanical fixings, the mounting block in the case of encapsulated systems, and the housing of the scale. .When using external pulse-forming electronics (EXE) the ground must be electrically connected with the frame of the machine. Necessary cable cross-section ≥ ∅ 6 mm². .Encapsulated linear measurement systems should be connected to compressed air.

3-30 TNC 407/TNC 415/TNC 425 5 Measuring systems 01.98

Please check that the mounting block, the sensor unit and the scale housing all have a good electrical connection with the chassis/frame of the machine. Since the connector for the measuring system and the mounting block are connected by the outer screen of the connector cable, this test can be carried out between the measuring system connector and the measuring system housing. During this test the connector must not be plugged in to the logic unit, as this would cause a grounding via the logic unit.

6.2 Connecting cable

HEIDENHAIN offers a connecting cable with a connector at one end (Id.-Nr. 290 109 ..).

The connecting cable to the nominal value outputs may not have more than one intermediate terminal. The terminal must be made in an earthed connection box. This is necessary when the cable must branch to physically separate servo inputs. It is only possible to earth the screening of the servo leads in this way. If required, suitable connection boxes are available from HEIDENHAIN with the Id.-Nr. 251 249 01.

3-32 TNC 407/TNC 415/TNC 425 6 Nominal value output 01.98

The casing of the connection box must be electrically connected with the frame of the machine. The 0 V of the nominal value differential input must be joined to signal ground, (cable cross-section ≥ Ø 6 mm², see also under "Earthing plan"). Suggested solution for connecting and wiring the screening in the connection box:

7 Reference pulse inhibit input

The reference pulse inhibit input can be used to suppress the evaluation of the reference pulse input of each of the six measuring systems. This is achieved by simply applying a positive potential (13 V to +30.3 V) to the appropriate reference pulse inhibit input. Pin 9 of the female connector X10 (reference pulse inhibit) must be connected to 0 V of the PLC-power supply.

The reference pulse inhibit inputs are only available in the LE 415 A. These inputs are normally unused. See also Chapter "Machine Integration".

9 Data interface

The HEIDENHAIN contouring controls TNC 407 and TNC 415 have two data interfaces:

one RS-232-C/V.24 data interface and one RS-422/V.11 data interface.

Both interfaces may be utilised. The operator decides which of the two interfaces he wishes to use. See also chapter "Data interface".

9.1 RS-232-C/V.24 data interface

HEIDENHAIN guarantees that, if properly connected, the serial data interface RS-232-C/V.24 will transmit data correctly up to a distance of 20 m between the logic unit and the peripheral unit.

The connection to the peripheral unit is made via a cable adapter which is attached to either the operating console or the control cabinet. See also under the heading "Mounting dimensions".

This cable adapter (Id.-Nr. 239 758 01) is connected to the logic unit with the HEIDENHAIN cable Id.Nr. 239 760 ..

For connection to the peripheral unit HEIDENHAIN offers a standard connecting cable (Id.-Nr. 274 545 01) , length 3 m.

10.5 Handwheel adapter HRA 110

The HRA 110 can be used to connect 2 or 3 handwheels HR 150 to one LE.

The first two handwheels are dedicated to axes X and Y. The third handwheel can be assigned to axes X, Y, Z, IV or V using a step switch (optional) or machine parameters. (See "Handwheel" section in chapter "Machine integration").

A second step switch (optional) can be used to select the interpolation factor for the handwheels. The interpolation factor of the step switch must be evaluated in the PLC - it is displayed on screen but cannot be altered with the keyboard. However the interpolation factor can be set for specific axes without a step switch by using the keyboard as before.

12 Machine operating panel

A separate 37-pin female connector (X46) is mounted on the logic unit for the connection to the machine operating panel. This connector includes the PLC inputs I128 to I152, the PLC outputs O0 to O7, as well as the 0 V and +24 V of the PLC power supply. The PLC inputs I128 to I152 may be connected only with the power supply from pins 36 and 37, since this power supply is internally secured as required.

HEIDENHAIN now offers a machine operating panel. It is installed beneath the TNC keyboard. The dimension drawings show the standard set of keys. Four additional black keys are supplied with the panel. The machine tool builder to use them replace unneeded axis keys, for example. Keys with other symbols are also available upon request.
