Foreword

This Technical Manual has been written for all machine tool manufacturers and distributors. It contains all of the information necessary for the mounting, electrical connection, commissioni ng and PLC prog ramming of HEIDENHAIN contouring controls. Every time the hardware or software of HEIDENHAIN's contouring control is updated, you will receive a set of supplementary pages free-of-charge. Always sort these pages into your Technical Manual immediately. In this way, your manual will always be up-to-date. You can use extracts from this manual to supplement your machine documentation. If you increase the size of the manual format (17 cm x 24 cm) by the factor 1.225, you will have DIN A4 format. No documentation can be perfect. To stay up to date, documentation must change constantly. It also thrives on your comments and suggestions for improvement. Please help us by sending us your ideas.

2 Introduction

2.1 General Information

HEIDENHAIN contouring controls are designed for use with milling, drilling and boring machines as well as machining centers.

The iTNC 530 features integral digital drive control and controls the power stages via PWM signals.

Integration of the drive controllers in the iTNC 530 offers the following advantages:

n 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.

n High control quality, because the position controller, speed controller and

current controller are combined into one unit.

n The same functions are available for commissioning, optimizing and

diagnosing feed drives as well as spindles.

The iTNC 530 offers digital control for up to five or nine axes and for spindle speeds up to 40 000 rpm.

The iTNC 530 is designed for connection of a compact or modular inverter system. Thus, together with HEIDENHAIN motors, a complete control package including servo drive can be supplied (see Technical Manual "Inverter Systems and Motors").

2.4 Software

2.4.1 Designation of the Software

The iTNC 530 features a separate software for the NC and the PLC. The NC software is identified with an eight-digit number.

If you press the MOD key in any operating mode, you can display the ID numbers of the NC software, the DSP software (DSP1, DSP2) and the currentcontroller software (ICTL1, ICTL2).

Type The iTNC 530 is shipped with the following NC software version:

Standard Export

340 420-xx 340 421-xx

Due to restrictions on the export of the iTNC 530, HEIDENHAIN can also supply a special export version. This export version differs from the standard control though the installed NC software type. HEIDENHAIN releases a new NC software type whenever it introduces extensive new functions.

2.4.2 PLC Software

The PLC software is stored on the hard disk of the TNC. You can order a PLC basic program directly from HEIDENHAIN. With the PLC development software PLCdesign, the PLC program can very easily be adapted to the requirements of the machine.

2.4.3 Enabling Additional Control Loops

For each MC 422, only the minimum number of control loops is enabled. If you need additional control loops, you must enable them by entering a code number. These additional control loops are not bound to a certain machine parameter index.. The definition as to whether a control loop is used is entered as a value ≠ 0 in MP120.x (nominal speed value outputs to the axes) and MP121.x (nominal speed value outputs to the spindles).

Each MC 422 can be clearly identified by the SIK (System Identification Key).

Position of the SIK in the MC

SIK (System Identification Key)

If you wish to enable additional control loops, please contact HEIDENHAIN for the code number. After you have informed us of the SIK number, we can give you the required code number.

You will find the SIK number on the outside of the MC 422 housing (below the ID label) and on the SIK board.

Note

If you replace the MC 422, you must also replace the SIK in order to ensure that the enabled control loops will also be enabled on the new MC 422.

2.4.4 NC software exchange

Soft key Function

Note

The NC software must be exchanged only by trained personnel.

For exchanging the NC software, HEIDENHAIN provides packed files(*.zip) with the NC software. The packed files are transferred to the hard disk of the control and unpacked. The packed files remain on the hard disk of the control.

Convert the files on the hard disk from binary format to ASCII format and save nonvolatile markers in the PLCMEM.A file.

Copy cutting-data tables, tables for tilting-axis geometry, and tables of M-function macros from the SYS partition into the corresponding directories of the TNC or PLC partitio n .

Activate or delete existing NC software.

Exchange the NC software.

Procedure for exchanging the NC software

Before exchanging the NC software, ensure that the free space on the hard disk of the MC 422 is at least 50% the size of the occupied space. If that is not the case, you must save the files to a PC, e.g., with the TNCremoNT datatransfer software for PCs.

Note

When the control starts, it checks whether there is enough space on the hard disk for system files. If not, the error message Too many setup files appears. In this event, delete any unnecessary setup files from the hard disk. (See “Deleting the packed files of existing NC software” on page 2 – 33.)

7 While in the Programming and Editing operating mode, press the MOD key. 7 Enter the code number 95148 and confirm your entry with the ENT key.

3.1 General Information

Warning

Keep the following in mind during mounting and electrical installation:

n National regulations for power installations n Interference and noise immunity n Conditions of operation n Mounting attitude

3.1.1 Degrees of Protection

The following components fulfill the requirements for IP54 (dust and splashproof protection).

n Visual display un it (when pr operly installed) n Keyboard unit (when properly installed) n Machine operati ng panel (when properly installed) n Handwheel

3.1.2 Electromagnetic Compatibility

Likely sources of interference

Protective measures

This unit fulfills the requirements for Class A according to EN 55022 and is intended for operation in industrially zoned areas.

Protect your equipment from interference by observing the following rules and recommendations.

Noise is mainly produced by capacitive and inductive coupling from electrical conductors or from device inputs/outputs, such as:

n Strong magnetic fields from transformers or electric motors n Relays, contactors and solenoid valves n High-frequency equipment, pulse equipment and stray magnetic fields from

switch-mode power supplies

n Power lines and leads to the above equipment

n Keep a minimum distance of 20 cm from the MC 422, CC 422 and its leads

to interfering equipment.

n Keep a minimum distance of 10 cm from the MC 422, CC 422 and its leads

to cables that carry interference signals. For cables in metallic ducting, adequate decoupling can be achieved by using a grounded separation shield.

n Shielding according to EN 50 178 n Use potential compensating lines with 6 mm n Use only genuine HEIDENHAIN cables, connectors and couplings

3.2 Shipping Brace of the Hard Disk

The hard disks of the MC 422 are fitted with a shipping brace. The shipping brace consists of two screws, which are used to secure the hard disk to the housing of the MC 422. There are also two additional free threaded holes in the housing, into which the screws are inserted after the hard disk has been released.

When is it necessary to use the shipping brace?

n Before beginning operation, the shipping brace of the hard di sk must be

removed and the screws inserted in the storage holes.

n The shipping brace for the hard disk is not required when the machine is

being transported.

n Should servicing become necessary (i.e. the MC 422 is being shipped on its

own), the hard disk must be secured with the shipping brace.

3.3 Environmental conditions

3.3.1 Heat Generation and Cooling

The permissible ambient temperature in operation is between 0 °C and 45 °C. Any deviation from this will impair the operating safety of the machine. The permissible storage temperature is between –35 °C and +65 °C.

The following measures can ensure adequate heat removal:

n Provide sufficient space for air circulation. n Build in a fan to intensify the natural convection. The fan should extract the

warm air from the MC 422 and CC 422. There must be no pre-warmed air blown into the unit. The warmed air should flow over surfaces that have good thermal conductivity to the external surroundings.

n For a closed steel housin g without assisted cooling,

The proposed value for heat conduction is 3 Watts/m2 of surface per °C air temperature difference between inside and outside.

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

HEIDENHAIN advises against blowing external air through the control cabinet to replace the internal air. Electronic assemblies may be adversely affected by fine dust or vapors. If no other method of cooling is possible, then ensure that the fan extracts the warmed air from the electrical cabinet and that the air drawn in is adequately filtered. Regular servicing of the filter is essential.

3.5 Power Supply for the iTNC 530

The UV 1x0 or the UV 105 power supply unit supplies the iTNC 530 with power. Power is supplied through X69 and, with the UV 105, in addition through a 5 V terminal on the CC 422.

For information on the UV 1x0 supply units, refer to the Technical Manual “Inverter Systems and Motors.”

Whether the UV 1x0 supply unit is sufficient or whether a UV 105 is needed as additional equipment, depends on the current consumption of the used units.

Note

For the NC to be able to evaluate the status signals of the UV 1x0 power supply units, connector X69 must be connected by ribbon cable with X69 of the UV 105. Since non-HEIDENHAIN inverters do not send any status signals, an adapter connector (Id. Nr. 349 211-01) must be connected to X69 on the UV 105. This connector is delivered with the UV 105.

3.11 Encoder Connections

3.11.1 General Information

HEIDENHAIN contouring controls are designed for use with incremental linear and angular encoders as measuring systems. The encoder signals are interpolated 1024-fold. Encoders with one reference mark or distance-coded reference marks and with EnDat interface are permissible. HEIDENHAIN recommends the use of ab solute encoders with EnDat interface or the use of encoders with distance-coded reference marks because they greatly reduce the traverse distance required to establish the absolute position.

Please use only HEIDENHAIN encoder cables, connectors and couplings. For maximum cable lengths, see “Cable Overview” at the end of this chapter.

corresponding analog outputs on terminal X8 or X9 to the nominal speed outputs.

n The connecting cables to the nominal value outputs must not have more

than one intermediate terminal.

n If you must branch to physically separate servo inputs, the connection must

be made in a grounded terminal box, e.g. Id. Nr. 251 249-01 from HEIDENHAIN. The housing of the terminal box must be electrically connected with the frame of the machine.

n The 0 V connections of the nominal-value -d if f erence inputs must be

connected with the signal ground. Cross section ≥ 6 mm

n Use only original HEIDENHAIN cables and connecting elements.

Output signals and addresses

The switching outputs are transistor outputs with current limitation. Please note:

n Permissible load: Resistive load—inductive load only with quenching diode

parallel to inductance

n Short circuiting of one output is permissible. No more than one output

may be short-circuited at one time.

n No more than half the PLC outputs may be driven at the same time

(simultaneity factor 0.5)

Output signals:

MC 422 PL 4xx B
