MP7680 expanded:
Bit 10 see item 1.1.2 "Optimization of Tool-Radius-Compensated Outside Corners."
The software also runs on the old hardware of the LE 426 CB/PB and LE 430 CA/PA, however
with less feature content.
1.1.1 Nominal Position Value Filter
For optimum adjustment of the velocity and acceleration the nominal position values are filtered. This results in smoother (jerk-limited) traverse. The TNC calculates the filter parameters weighting and width (order) using the permissible axis-specific jerk and the tolerance. The filter is effective in all operating modes. For rigid tapping (Cycle 17) the nominal position value filter is automatically switched off.
With MP1095 you can select whether the TNC uses a single or double filter. The single filter causes a linear change in acceleration and therefore a step in the jerk.
With Cycle 32 the user can overwrite the tolerance defined in MP1096 for contour transitions. Cycle 32 was renamed to "fast contour milling" because the nominal position value filter is effective not only for 3-D contours.

In MP1098.x enter twice the value from MP1097.x.Define the tolerance in MP1096 (e.g. 0.02 mm)
1.1.2 Optimization of Tool-Radius-Compensated Outside Corners
With MP7680, bit 10 you set whether a circular arc or a spline should be inserted for the tool center path at tool-radius-compensated outside corners. Inserting a spline has the advantage of limiting the jerk at the corners and, when the nominal position value filter (MP1096 > 0) is active, of milling the corners more precisely.

1.1.3 New Backlash Compensation
A new type of backlash compensation is effective beginning with NC software 280 470 08 and 280 472 01. Unlike the backlash compensation possible with MP710, you can compensate the backlash in the entire controlled system with MP750 and MP752. This means that you can now also compensate play between the motion of the motor and the table with position measurement via linear encoders. This feature also compensates the reversal spikes resulting from circular traverse, and the machine parameters MP711 to MP716 are therefore no longer needed.
In MP750 you enter the backlash in mm. In MP752 you enter the time within which the compensated distance should be traversed.
Example: MP750 = 0.03 mm, MP752 = 15 ms For every reversal in axis direction, for 15 ms a nominal speed command signal is output corresponding to a feed rate of 120 mm/min (0.03 mm / 15 ms = 0.002 m/s = 120 mm/min).
MP750 Backlash Input: –1.0000 to +1.0000 [mm] MP750.0-8 Axis 1 to axis 9
MP752 Compensation time for value from MP750.x Input: 0 to 1000 [ms] MP750.0-8 Axis 1 to axis 9

At the reversal point the actual feed rate lags behind the actual RPM with the time delay Input values: MP750 = t • ∆ACTL.SPEED
MP752 = approx. 20 ms (optimum value determined empirically with this test)
.
1.1.4 Other Changes in the Technical Manual
MP7460 (constant contouring speed at corners) has been replaced by MP1096 (tolerance), pages
4-77, 9-45.
MP1091 (Jerk limiting for 3-D milling with Cycle 32) will not be introduced, pages 4-62, 4-78,
9-13.
Module 9037 (read general axis information) was renamed to Module 9038, pages 4-7,

2 Introduction
2.1 Integrated Current Control
HEIDENHAIN contouring controls are designed for integration in milling, drilling and boring machines as well as machining centers.
The TNC 426 PB / TNC 430 PA has integral drive controllers; these control the drive amplifier by means of Pulse Width Modulated (PWM) signals. Integration of the drive controllers in the TNC 426 PB / 430 PA offers the following advantages:
All the software is contained centrally in the NC; this means that the individual components of
the NC such as feed axes, spindle, NC or PLC are optimally matched.
High control quality, because the position control, speed control and current control are
combined into one unit.
For commissioning, optimization and diagnosis, the same functions are available both for the
feed drive and the main spindle.
The TNC 426 PB can control machines with up to five axes and spindle speeds up to 9000 rpm, option: 15 000 rpm (spindle speeds are valid for motors with two pole pairs). Powerful microprocessor hardware and an integrated hard disk with 900 MB guarantee almost unlimited NC memory and a short processing time — even for long programs. These are ideal preconditions for tool and mold construction.
The TNC 430 PA supports six digitally controlled NC axes and three analog controlled secondary axes, as well as digitally controlled spindle speeds up to 15 000 rpm (for motors with two pole pairs).
Control concept of the TNC 4xx PA
The TNC 426 CB is the version of the TNC 426 that is equipped with analog speed command interface and can control machines with up to five axes plus spindle.
The TNC 430 CA also has analog speed command interface for machines with up to eight axes plus spindle. A ninth axis can be controlled with an additional PCB.

2.3 Software
The logic unit contains separate software for the NC section and the PLC section. The software is identified by an eight-figure number.
After switching on the control, the NC software, PLC software and software-options numbers are displayed on the screen. The software number can also be directly requested with the aid of the MOD function.
2.3.1 NC Software
NC software number
The first 6 figures of the NC software number identify the type of control, the last two identify the version of the software.
Software type
Due to restrictions on the export of the TNC, HEIDENHAIN can also deliver a special export version. This export version differs from the standard control through the installed software type. HEIDENHAIN assigns a new software type whenever comprehensive new functions are introduced.
Software type Linear interpolation

2.3.2 Software Option
HEIDENHAIN offers “Digitizing with a Triggering Touch Probe” and “Digitizing with Triggering and Measuring Touch Probes” as software options (see chapter “Machine Integration”). Whenever a contouring control is ordered with one of these options, HEIDENHAIN installs an additional software module or PCB in the logic unit and assigns another variant to the part identification number (Id. Nr.) of the logic unit. The option number is displayed on the screen in addition to the NC and PLC software numbers.

2.3.3 PLC Software
The PLC software is stored on the hard disk of the TNC. HEIDENHAIN has developed a PLC commissioning program for the TNC. The source code is available from HEIDENHAIN. This program can be easily adapted to suit your machine with the PLC programming software PLCdesign.
2.3.4 Software Exchange
The NC software is located on EPROMs (the sockets are illustrated below). The dialog languages are stored on the hard disk. If there are no up-to-date dialog languages on the hard disk, load the English dialog language from the EPROMs (selectable with MP7230.x). If a software exchange becomes necessary, HEIDENHAIN dialog languages.
Procedure for software exchange:
The software must be exchanged only by trained personnel.
Enter the code number 95148Press the MOD keyPress the UPDATE DATA and CONVERT BIN=>ASC soft key:
All files on the hard disk will be converted from binary to ASCII format. The free space on the hard disk must be at least 50% larger than the largest file. If this is not the case you must save this file through the data interface. The extensions of the binary files and of the corresponding converted ASCII files are: .H .H% .I .I% .T .T% .TCH .TC% .D ⇔ .D% .P .P% .PNT ⇔ .PN% .COM ⇔ .CO% .CMA .CM%

Press the END key to exit the machine parameter editor. The error message LANGUAGE LOAD
ERROR appears.
On the PC, enter the SETUP command to load the NC dialogs, HEIDENHAIN cycles etc. from the
provided floppy disk. The floppy disk also contains a detailed description in the README.TXT file.
Press the UPDATE DATA and CONVERT ASC=>BIN soft key:
All files on the hard disk are converted from ASCII into binary format.
Reload the files that you have backed up through the data interface.Switch the TNC off and on to activate the new NC dialogs.
2.3.5 Data Backup
HEIDENHAIN provides a free program, TNCBACK.EXE, for backing up files in the TNC 426. We recommend to the manufacturer whenever he supplies a machine tool to also provide a floppy disk containing a copy of all machine-specific data, backed up with TNCBACK.EXE. The floppy disk must also contain a copy of TNCBACK.EXE.
Before exchanging his control unit, the customer can save the data from the TNC, especially the TNC:\ partition with its directories containing the part programs (see the user's instructions on the floppy disk).
2.4 Hardware
The eight-digit ID number of the logic unit consists of the 6-digit basic ID number followed by the 2­digit version number. The basic ID number designates significant hardware differences (e.g. type of logic unit encoder inputs). The version number identifies the following differences:
version xy: x = Identifier for a hardware change y = 3 = Export version with “Digitizing with Triggering Touch Probe” option
4 = Standard version with “Digitizing with Triggering Touch Probe” option 7 = Standard version with “Digitizing with Measuring and Triggering Touch Probes” option 8 = Export version without option 9 = Standard version without option

3 Mounting and Electrical Installation
3.1 Electrical Noise Immunity
Location for use
This device corresponds to Class A according to EN 55022 and is intended primarily for operation in industrially zoned areas.
Remember that the vulnerability of electronic equipment to noise increases with faster signal processing and higher sensitivity. 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 that carry interference signals are laid together in metallic ducting, adequate decoupling can be achieved by using a grounded separation shield.)
Shielding according to IEC 742 EN 50 178.
Potential compensating lines dia. 6 mm² (see Grounding Diagram).
Use of original HEIDENHAIN cables, connectors and couplings.

3.2 Heat Generation and Cooling
Please note that the reliability of electronic equipment is greatly reduced by continuous operation at high temperatures. Be sure to 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 that 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.
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, vapors etc.). In addition to these disadvantages, a filter that is not adequately serviced leads to a loss in cooling efficiency. Regular servicing is therefore absolutely vital.

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 not be switched off, so that condensation is avoided on the circuit boards. The heat generation prevents condensation and has no further disadvantages.

3.8 Power Supply
3.8.1 NC Power Supply
LE 426 CB, LE 430 CA:
An NC power supply of 140 Vac to 450 Vac at terminals U and the LE 430 CA. Power supply monitoring is switched off with Module 9167. To ensure compliance with the European standards for electromagnetic emission (EN 55022), the LE may be connected to the public power lines only through an isolating transformer or in conjunction with line filters. Compliance to these standards is one of the requirements for the use of the CE mark. If a line filter is already provided for the power stage, this power supply may also be used for the LE.
LE 426 PB, LE 430 PA:
For the LE 426 PB and the LE 430 PA, an NC power supply of 330 Vac to 450 Vac must be connected to U
and U2. Here however this must be supplied via an isolating transformer (100 VA)
1
with basic insulation according to IEC 742 EN 50 178.
To guarantee a secure power supply for the drive controllers in the event of a power failure,
the LE must be supplied with the DC link voltage of the power stage (385 Vdc to 660 Vdc) at the terminals +U
and −U
Z
If the DC link voltage is guaranteed to be available after switching the main

feedback to the DC link is possible. If 385 Vdc is not reached (power fail), all drives are brought to a stop under control. This power supply monitoring is enabled and disabled with Module 9167. If the voltage falls below 155 Vdc, a control unit reset takes place; the dc link power supply disconnects at 135 Vdc.

3.8.2 Buffer Battery Backup
When the control is switched off, a buffer battery backup supplies the TNC with enough power to prevent data being lost from the RAM memory. If the message EXCHANGE BUFFER BATTERY appears on the TNC it is time for you to change the batteries. The batteries can be found in the logic unit, beside the power supply (round, black housing). The TNC also has an energy storage mechanism for supplying power to the TNC while the batteries are being changed (max. stored energy time: 24 hours).
Danger of electrical shock!
The machine tool and the TNC should be switched off while the battery is being changed! The buffer batteries may only be changed by trained personnel!

3.9 Measuring Systems
r
HEIDENHAIN TNC contouring controls are designed for use with incremental linear and angular position feedback encoders as measuring systems.
It does not matter whether the encoders feature single or distance-coded reference marks, the TNC supports both types. However, HEIDENHAIN recommends using encoders with distance­coded reference marks because they significantly reduce the traverse distance required to establish the absolute position.
Maximum current consumption per encoder input: 200 mA Maximum total current consumption for all encoder inputs:

Connection X9: analog output 7 to 13
PLC analog outputs
The PLC analog outputs can be switched via Module 9130.
Nominal value output:
For analog axes and analog spindle, use MP120.x and MP121 to assign the corresponding analog
outputs on connection X8 or X9 to the nominal speed outputs.
The connecting cables to the nominal value outputs must not have more than one intermediate
terminal.
If it is necessary to branch to physically separate servo inputs, the connection must be made in a
grounded terminal box. Suitable terminal boxes is available from HEIDENHAIN (Id. Nr. 251 249
01).
The chassis of the terminal box must be electrically connected with the frame of the machine.
The 0 V connection of the nominal-value-difference inputs must be connected with signal ground. Required cross section Ø 6 mm².
Use only original HEIDENHAIN cables and connecting elements.
The following wiring plan is suggested for shielding the terminal box:

3.15.4 Handwheel Adapter HRA 110
You can connect two or three HR 150 panel-mount handwheels to the TNC using the HRA 110 handwheel adapter. The first two handwheels are assigned to axes 1 and 2. The third handwheel can be assigned to axes 1 to 5 either via a step switch (option) or with MP7645 (see also the chapter on "Machine Integration").
