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, commissioning and PLC programming 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 is perfect. Documentation is alive. It thrives on your comments and suggestions for improvement. Please help us by sending us your ideas.

	T-DC, F-DC, T-AC, F-AC, T-IGBT, I-N-AC-3333, I-N-AC-4000, I-N-AC-5000,
	I-N-AC-6666, I-N-AC-8000 and I-N-AC-10000. The columns currently have no
	function.
	n The motor table was expanded by the following columns T-DC, F-DC, T-AC
	and F-AC. The columns currently have no function.
Miscellaneous	n In the Machine-parameter programming mode, the DELETE ALL and SELECT
	soft keys after the DEL/SEL SETUP soft key were switched.

1.4 Use of Speed Encoders with EnDat Interface

Regardless of the Type of encoder in the motor table, the control attempted to communicate with a speed encoder with EnDat interface. If this did not succeed, a speed encoder with Z1 track was assumed.

If an error occurred during communication with the EnDat encoder, the control assumed that it was dealing with an encoder with a Z1 track. This was not the case, however, since encoders with EnDat interface do not have a Z1 track.

This resulted in the error message C310 Z1 track error.

As of NC software 280 476-18 (in conjunction with the setup 286 197-22), the control uses the Type of encoder entry in the motor table. If an encoder with Z1 track is entered in the motor table, the message C310 Z1 track error appears in the event of an error. If an encoder with EnDat interface is entered in the motor table, the control attempts to communicate with the encoder. If this fails, the error message C3F0 EnDat not found <axis> appears.

Warning

If you use the HEIDENHAIN standard motor table motor.mot and motors with EnDat encoders, you might have to change the entry for the motor in the SYS column (type of encoder) of the motor table or enter a new motor.

nSYS = 1: Incremental rotary encoder with Z1 track

nSYS = 2: Absolute speed encoder with EnDat interface

If you use the motor table motor.sn instead of motor.mot, the control attempts to communicate with an encoder with EnDat interface. If this fails, due to an error or because no EnDat encoder is connected, the control assumes that it is dealing with an encoder with Z1 track and tries to read it. If this fails, the error message C310 Z1 track error appears.

1.5 Tool-Oriented Machining

As of NC software 280 476-17, “tool-oriented” pallet table machining is also possible. For more information, please refer to the User's Manual.

A special tool-change macro is required for tool-oriented pallet machining. This is defined through the keyword TCTOOLMODE= in NCMACRO.SYS.

This macro is called for tool oriented machining instead of the tool-change macro. If this macro is not defined in NCMACRO.SYS, a HEIDENHAIN standard macro is run.

The HEIDENHAIN standard macro performs the following functions:

nPositioning to clearance height

nExecution of M146

nTool change through TOOL CALL. The existing tool-change macro is called.

The following new functions are available for interrogating whether a clearance height was programmed in the pallet table:

nFN18: SYSREAD ID510 NR5 IDX(axis)

This function can ascertain whether a clearance height was programmed for the corresponding axis.

nFN18: SYSREAD ID510 NR6 IDX(axis)

This function can ascertain the clearance height for the corresponding axis.

With the M function M146 the current geometry information is saved in a temporary file.

An NC macro can be defined through the keyword CLAMP= in NCMACRO.SYS. The macro is called when a loaded fixture (FIX) is called.

In addition to the standard prototype for pallet tables, the COPY SAMPLE FILES soft key copies the prototype for tool-oriented pallet table machining into the PLC:\PROTO directory. Both prototypes are offered when you create a new pallet table. If you do not want this, delete a prototype from the PLC:\PROTO directory. The existing prototype is then used automatically.

nPrototyp.P = standard prototype

nProto_to.P = prototype for tool-oriented machining

1.6 Field Orientation

If a synchronous spindle is used along with an encoder without Z1 track or a nonaligned encoder with EnDat interface, there is no assignment between the encoder and rotor magnets. This is remedied by NC software 280 476-13 with the new FIELD ORIENTATION function on the LE 426 M/30 000 rpm and the LE 430 M. When put into service, the control automatically finds the assignment between the encoder and the rotor magnets and saves this information on the hard disk. From this time on the assignment is available to the servo controller.

1.7 New Motor Table

As of NC software 280 476-13, the motor table motor.mot is used as the standard table instead of the previous standard motor tables motor.asn and motor.sn. Synchronous and asynchronous motors are registered in motor.mot. If the new motor table motor.mot is not available, the control looks for motor.asn and motor.sn.

You can transfer asynchronous motors from motor.asn into motor.mot. To transfer synchronous motors into motor.mot, please contact HEIDENHAIN.

1.8 Hardware

New receiver units The EA 550 and EA 552 receiver units and the APE 511 interface electronics for the connection of two EA 552 to the LE have been superseded by new units.

Old units	New units
EA 550 (Id. Nr. 262 904-xx)	EA 632 (Id. Nr. 346 322-xx)
EA 552 (Id. Nr. 339 317-xx)	EA 652 (Id. Nr. 346 323-xx)
APE 511 (Id. Nr. 275 759-xx)	APE 652 (Id. Nr. 354 656-01)

LE 430 M/9 axes On the LE 430/9 axes with flash EPROMs, only the speed encoder inputs and with flash EPROMs the position encoder inputs X1 to X6 (but not X35 to X38) are equipped with

EnDat interface.

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 TNC 426 PB/M, TNC 430 PA/M features integral digital drive control and controls the power stages via PWM signals.

Integration of the drive controller in the TNC 426 PB/M, TNC 430 PA/M offers the following advantages:

nAll 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.

nHigh control quality, because the position controller, speed controller and current controller are combined into one unit.

nThe same functions are available for commissioning, optimizing and diagnosing feed drives as well as spindles.

With the TNC 426 PB, up to five axes and spindle speeds of up to 12 000 rpm can be controlled digitally (option: 30 000 rpm).

The TNC 430 PA supports up to 6 digitally controlled NC axes, 3 analog controlled secondary axes, and digitally controlled spindle speeds up to 30 000 rpm.

December 2001

General Information

2 – 3

The TNC 426 M offers digital control for up to 5 axes and spindle speeds up to 12 000 rpm (option: 30 000 rpm). The TNC 430 M offers digital control for up to six or nine axes and spindle speeds up to 30 000 rpm.

The TNC 426 M, TNC 430 M 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 offered (see Technical Manual “Inverter Systems and Motors”).

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 an analog speed command interface for machines with up to eight axes plus spindle. A ninth axis can be controlled with an additional PCB.
