Update Information No. 8

In mid February 1996 software version 17 was released for the NC software types 260 02 and 280 49, and for the newly introduced software types 260 060 (for 1 MB EPROMs) and 280 610 (for 2 MB EPROMs). The new software types were introduced for the Polish conversational language.

Software version 17 contains the following additions:

• The software now supports the new handwheel HR 410.

The HR 410 is a portable electronic handwheel with:

Keys for selection of five axes Keys for traverse direction Keys for three pre-programmed feed rates for latched traverse One key for actual-position capture Three keys for machine functions determined by the machine manufacturer Two permissive buttons Emergency stop button Magnetic holding pads

With MP7640 = 6 you can activate the functions for the HR410 handwheel.

MP7645.0 determines whether the keys on the handwheel are assigned to the NC or the PLC.

MP7645.0 = 0 NC key assignment

Update Information No. 5

For NC software types 260 02 and 280 49, software version 13 was released in mid-June1994, software version 14 at the end of June, and software version 15 at the beginning of July.

Software version 13 contains the following enhancements:

The input range for machine parameter MP1350 (type of reference mark approach) was

expanded. An input value of 3 selects encoders with distance-coded reference marks, and thedirection of traverse reverses when the trip dog for the reference end position is crossed.

Data transfer in blockwise mode (ACK/NAK protocol) could be interrupted if the control characters STX or ETB were transmitted incorrectly. Since the TNC did not know the cause of the interruption, it sends NAK (after a delay in which no further data are transferred) if a block was not completely recognized due to a faulty STX or ETB.

If ACK is not received within a certain time, the error message TRANSFERRED DATA

INCORRECT N is generated.

If bit 3 in machine parameter MP7641 is set, the electronic handwheel is selected in each

operating mode (initially before REF traversing) to be able to interrogate the inputs of the handwheel keys (except axis keys) in the PLC. The axis keys on the handwheel and the handwheel impulses do not become active until handwheel mode is selected. After an error the handwheel is not selected again until the handwheel key is pressed.

If the operating voltage of the control is outside the limit values, the blinking error message

PROCESSOR CHECK ERROR M is displayed.

The input range of machine parameter MP4220 has been expanded to 0 ... 65535.

The memory for the executable PLC program has been increased from 28K bytes to 32K bytes.

The value for the analog voltage of the analog input at connector X8 is transferred to word

W392.

The meaning of machine parameter MP7225 (automatic block generation with the capture

actual position key or with PLC marker M2829) has been changed as follows: MP7225 = 1 : Block generation with the capture actual position key MP7225 = 2 : Block generation with PLC marker M2829 MP7225 = 0 : No block generation

The resolution of the feed rate display depends on the programmed feed rate:

Feed rate ≤ 31 999 mm/min (previously 29 999 mm/min): display step 2 mm/min Feed rate > 31 999 mm/min (previously 29 999 mm/min): display step 20 mm/min

Software version 14 was released to correct the following error:

If a STOP and an M function for PLC positioning were executed in one NC block, in the

following block an M function that becomes effective at the beginning of the block (e.g., M3) was not executed!

7/94 TNC 360/TNC 335 Update Information No. 5 1-1

Page 11

Software version 15 was released to correct the following error:

### If, in an OEM cycle that was run from the EPROM, the feed rate was defined via Q parameter,

a greatly excessive feed rate was ouput.

Update Information No. 4

In late February 1994, software version 12 was released for the NC software 260 02 and 280 49.

Note:

In software version 11, the deceleration ramp is too flat when the feed rate is changed at constant contour transitions during operation with feed precontrol. This error was corrected in software version 12.

Software version 11 must be replaced by software version 12!

No new features were introduce in software version 12.

2/94 TNC 360/TNC 335 Update Information No. 4 1-1

Page 13

Update Information No. 3

Software version 11 for software types 260 02 and 280 49 was released at the end of January 1994. Software version 10 was not released for general distribution.

The following improvements were made since version 9:

Machine parameter 7411 defines whether during execution of the TOUCH-PROBE block the

•

current compensation values for probe length and radius should be taken from the central tool file or from the calibration process.

MP7411 = 1 : Probe length and radius values from the tool file MP7411 = 0 : Probe length and radius values from the calibration process

MP 7411 is also effective for tool length compensation in the digitizing cycles. This machine parameter was already available in version 08, but it was not documented.

Machine parameter MP7225 was introduced for automatic generation of NC blocks in the

•

PROGRAMMING AND EDITING mode. With the "actual position capture" key (teach-in) it is now possible to generate a positioning block in plain language dialog (not in ISO mode) with a maximum of 3 axes and without feed rate, radius compensation or M-functions. This positioning block is inserted below the currently addressed block in the selected NC part program. The current actual position values become the nominal position values. The axis is selected in the dialog "AXIS SELECTION =" in the MOD operating mode. Here up to 3 out of 4 axes can be selected by pressing the corresponding axis keys.

MP7225 = 1 : Block generation with the actual-position-capture key (teach-in) MP7225 = 2 : Block generation with the actual-position-capture key or with the PLC marker

M2829 (the marker is reset by the NC)

MP7225 = 0 : No block generation or axis selection possible.

If the machine parameters are erased, the RS-232-C/V.24 interface is now preset to FE mode.

•

PLC inputs I160 to I175 (HR 332 handwheel) now generate signal edges. The positive edge is

•

assigned to markers M1660 to M1675, the negative flank to markers M1860 to M1875.

If machine parameter MP7641, Bit 2 = 1, the interpolation factor for the handwheel can be set

•

both from the keyboard as well as from PLC module 9036. If Bit 2 = 0, the machine parameter functions as before (input either from the keyboard or from PLC module 9036).

The NC saves the code number entered in the MOD mode in Doubleword D276.

•

Machine parameter MP810 defines the modulo value for reducing the position values of the

•

auxiliary axes. Machine parameter MP7470 has no effect on auxiliary axes. Rotary axes as NC axes are always reduced to the range 0° to 359.999°. Machine parameter MP810 was already available in version 08, but it was not documented.

1/94 TNC 360/TNC 335 Update information No. 3 1-1

Page 14

The new PLC module 9124 makes it possible to set a feed rate override value for secondary

•

axes. The override value can lie between 0% and 100% (resolution 0.01 %) and must be transferred as a whole number (0 to 10 000). It can be set before the beginning of a movement or during the movement of an auxiliary axis. If the control is reset, the NC presets an override value of 100%.

Call : PS B/W/D/K <Axis> (0..3 for X/Y/Z/4) PS B/W/D/K <Override value> (0..10 000) CM 9124 PL B/W/D <Error code> 0: Override was set 1: Invalid axis was entered 2: Axis is not defined as auxiliary axis 3: Override value is invalid Error status after call: M3171 = 0 : Override was set = 1 : Error condition see above

If more than one of the PLC modules 9120/9121/9123 for controlling the movement of auxiliary axes is called within one PLC scan, only the last called PLC module is executed. The module 9124 can be called in addition to the above modules within one PLC scan, but it will always become effective after the other module.

In PLC module 9036 (transferring PLC status information to the NC) the interpolation factor can

•

be set for all axes by transferring the value 4 or 5.

The PLC can inhibit the reference pulse for specific axes through Word W608 (bit-

•

coded,....4zyx).

Bit = 1 : Reference pulse is not evaluated Bit = 0 : The next reference pulse is evaluated

By setting marker M2615 the reference mark of the spindle is evaluated again. The marker is

•

reset by the NC.

Marker 2510 fixes the spindle potentiometer setting at 100%. Marker M2511 has the same

•

effect on the feed rate potentiometer.

CC blocks in OEM cycles are effective only locally and are not transferred into the calling

•

program.

Update Information No. 2

In earl September 1993 the software version 09 was released for the software types 260 02 and 280 49.

The new version contains the following changes:

If marker M2612 (Suppress position exchange in the tool table) is set before a T strobe is set

•

(M2046), the position numbers are not exchanged. The PLC acknowledges the T strobe without having exchanged in the tool magazine and resets the PLC marker M2612. The new tool number is shown inverted and the associated tool data (length and radius) are activated. The tool number is shown inverted in the status display until the tool has physically been changed. If the control is switched off and on in this condition, the last exchanged tool becomes active again.

During execution of cycle 13 (spindle orientation) the NC sets the new marker M2408. This

•

marker can be evaluated by the PLC for the spindle orientation and should afterwards be reset by the PLC.

1 Software

In July 1993 the following software was released:

260 02x 08 for insertion of 1M byte EPROMs and 280 49x 08 for insertion of 2M byte EPROMs

The software numbers 280 49x 01 to 07 were not delivered. The new software version became necessary because new logic units can also accommodate 2M byte EPROMs (see below in Section 2 "Hardware").

The new software version contains the following changes:

The PLC can limit the maximum feed rate through the doubleword D596. In order to ensure

•

compatibility to previous PLC programs the doubleword D596 is preset with the value 300 000 mm/min after control switch-on or after interruption of the PLC run.

The new feed rate is effective immediately!

The doubleword D596 has no effect with the new cycles "Tapping" (Cycle 2) and "Rigid Tapping" (Cycle 17).

In the newly introduced machine parameter MP60, axes can be defined as auxiliary axes.

•

These axes cannot be moved by an NC program. They are controlled exclusively by the PLC.

All auxiliary axes work independently of each other. Auxiliary axes always move in trailing mode. The following modules are available for the PLC to control the axes: Module 9120: Positioning of auxiliary axes Module 9121: Stopping the auxiliary axes Module 9122: Status inquiry of auxiliary axes Module 9123: Traversing the reference point of an auxiliary axes

Spindle orientation can be suppressed at the beginning of Cycle 17 "Rigid Tapping" with

•

machine parameter MP7160. At the beginning of the cycle, the spindle voltage is decelerated with the ramp from MP3410.1 to the value 0 volts.

In this case it is not possible to cut into the same thread several times!

Up to 20 NC "tool def" blocks can be read-in during blockwise transfer without central tool

•

memory, whereby the tool def block must be read-in before the associated "tool call". When a "PGM call" NC block is read-in or when a user cycle is called, the NC blocks with "tool def" are considered up to the above mentioned limit and provided that the proper order is followed. A violation of these preconditions releases the error message "TOO MANY TOOLS".

9/93 TNC 360/TNC 335 Update information No. 1 1-1

Page 17

If bit 2 is set in machine parameter MP7300, the last inserted (programmed) tool is

•

automatically activated during switch-on.

By setting the static PLC marker M2612 the PLC can now prevent the exchange of pocket

•

numbers in the central tool memory during a P output.

Function FN19 was introduced, with which two numerical or Q parameter values with an

•

accuracy of 1/1000 (i.e., three places after the decimal point) are transferred into the PLC doublewords D280 and D284. A value of 2.5, for example, is filed in the doublewords as 2500.

The unit of measure of the calling NC program is set in marker M2150 (millimeter=0/inch=1).

During transfer the NC sets the strobe marker M2149. The transfer must be acknowledged by the PLC with the marker M2611.

The number of PLC labels was increased to 1024.

•

Marker M2614 was introduced. Setting this marker blocks the output of PLC functions

•

(M/S/T/Q output) by the NC. The marker is set and reset by the PLC; it is read by the NC.

Marker M2827 was introduced. It is set by the PLC and causes the following behavior in case

•

of an external EMERGENCY STOP and erasable positioning error: Machining is not aborted ("control in operation" symbol off, strobe signal reset). Instead, machining is merely interrupted as in an NC STOP (control-in-operation symbol blinks). This permits machining to be resumed with NC START after the error has been corrected. This marker functions only for the output of M/S/T/Q strobes.

Now a maximum of 32 Q parameters can be transferred for user cycles. To do this, the 'DLG-

•

DEF' or 'DLG-CALL' blocks must be programmed several times in the user cycle, whereby in the third DLG block only the first five entries can be evaluated.

The following Q parameters were introduced:

•

Q114 current tool length Q115 to Q118 measured values of the 4th axis after a programmed probing cycle

The type of tool compensation (R0/RR/RL/R+/R-) is stored in Q parameter Q123:

•

Q123 = 0 means R0 = 1 means RR = 2 means RL = 3 means R+ = 4 means R-

Application as positioning module:

•

If machine parameter MP 4010 = 1 is programmed (PLC program from RAM), no machine parameters will be taken from the PLC EPROM when the positioning module is switched on. If the CRC sum of the machine parameters is incorrect they will be taken from the PLC EPROM.

1-2 TNC 360/TNC 335 Update information No. 1 9/93

Page 18

The software now supports PLC subprograms stored in the PLC-EPROM (translated PLC

•

code). With the PLC.EXE programming software from HEIDENHAIN such programs can be written and on an external computer and filed in the PLC EPROM.

The incremental jog positioning can be activated or deactivated (dialog "JOG-INCREMENT: ...")

•

in the 'ELECTRONIC HANDWHEEL' operating mode by pressing the 'ELECTRONIC HANDWHEEL' key, provided that marker M2498 is set.

In the 'PROGRAMMING AND EDITING' operating mode the electronic handwheel can be used

•

to move the axes, provided that in machine parameter MP7641 bit 1 = 1. The interpolation factor (regardless of handwheel model) and the handwheel axis (for HR130) can be change only in the 'ELECTRONIC HANDWHEEL' operating mode. A handwheel axis, once chosen, remains in effect even when the operating mode is changed.

Simultaneous operation of the handwheel interface and the RS-232-C interface at differing baud rates (38 400 and 19 200 baud) results in the error message "BAUD RATE NOT POSSIBLE".

The current feed rate in mm/min is now available in the PLC.

•

Module 9150

•

During an active M/S/T output the PLC can use module 9150 to define an NC block, which is then executed after the M/S/T strobe is acknowledged, before the control continues the NC program. An NC block can also be defined if no program is being run. The block is then executed immediately.

Module 9120

•

Positioning an auxiliary axis

The positioning of an axis is started by presetting a target position (in the reference system), a feed rate and a flag register. The axis is positioned without regard to other processes in the control. There is no contour interpolation with other axes.

Conditions: The given axis must be activated via MP10 and configured as an auxiliary axis via MP60. The values for rapid traverse, analog voltage for rapid traverse, acceleration, etc., must be properly set in the machine parameters. For axes with automatic reduction (modulo value in MP810.x) the axis is always moved in the shortest direction to the target position, unless the target position is entered as an incremental value. There is no checking for violations of the limit switch ranges! The axis must be stationary. If the axis is already moving, the positioning must be terminated beforehand with module 9121. If the axis was in the reference point traversing mode, this state is canceled. The positioning always builds on the momentary counter contents. If the modules 9120, 9121 and 9122 are called several times during a PLC scan, only the last instruction is executed. If a "positioning error" status was set in this axis it is erased.

Potential errors: A non-existent axis was transferred. An axis was transferred that was not identified as an auxiliary axis in MP10 and MP60. The axis is already moving.

Call:

PS B/W/D/K <Axis> (0 to 3 for X/Y/Z/4) PS B/W/D/K <Target position> (in the reference system, Format 0.001mm) PS B/W/D/K <Feed rate> (mm/min) PS B/W/D/K <Flag register> Bit 0 = 1: incremental target position

•

Stopping a positioning with an auxiliary axis

A positioning started beforehand with modules 9120 or 9123 can be canceled at any time with module 9121.

Conditions: The given axis must be activated via MP10 and configured in MP60 as an auxiliary axis. If modules 9120, 9121 and 9122 are called several times for the same axis during a PLC-scan, only the last instruction will be executed.

Inquiring the status of an auxiliary axis

For a certain axis a bit-coded status word is transferred that contains information on the momentary operating state of this axis.

Conditions: Status changes causes by commands that the PLC sends to control the auxiliary axes (modules 9120, 9121, 9123) are not recognized until the next PLC scan. After switch-on, bit 1 (axis over reference point) is erased. It is possible to position the axis without traversing the reference point first.

PLC MODULE 9123

•

Passing over the reference point of an auxiliary axis

The module starts positioning in a preset direction, which continues until a reference point is found or the positioning is canceled with module 9121.

Conditions: The given axis must be activated via MP10 and configured as an auxiliary axis via MP60. The values for rapid traverse, analog voltage for rapid traverse, acceleration, etc., must be set in the machine parameters. There is no checking for violations of the limit switch ranges! The axis must be stationary. If the axis is already moving, the positioning must be canceled beforehand with module 9121. The feed rate override is not included in the calculation. The state "reference point not yet traversed" is set for the axis. A reference point that already exists in this axis is erased, but not the numerical value of the axis. This is not reinitialized until the reference point is found. If modules 9120, 9121 and 9122 are called several times during a PLC scan, only the last instruction is executed. If a "positioning error" status was set in this axis it is erased. The positioning is stopped as soon as the reference point is reached. Since the axis must decelerate before it can stop, it comes to rest behind the reference point in the direction of motion.

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 Grounding diagram). – 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 take the necessary measures to keep the unit within the permissible ambient temperature range.

Permissible ambient temperature in operation: 0° C to 45° C (BF 110: 0° C to 40° 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. – 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 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.

2.5.2 Visual display unit (VDU)

Permissible ambient temperature

BE 212 max. 45° C (113° F) BF 110 max. 40° C (104° F)

The VDU must be installed with a minimum clearance of 25 mm to the housing. It is recommended especially, that a large area is left free above the unit for heat removal.

Temperature is measured at a distance of 25 mm to the housing. The above mentioned temperatures must not be exceeded.

Please also note for the BE 212:

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.)

2.5.3 PLC Input/Output board PL 410

One PL 410 can be connected to the LE 360 C, if desired. There is no preferred mounting position for heat removal.

2.6 Degree of protection

When mounted, the visual display unit and the keyboard unit provide class IP54 protection against dust and splashwater.

The NC and the HRA 110 must not be supplied from the machine control voltage supply! It requires an individual, external and separately generated supply voltage according to VDE

0551. Use 24 Vdc with a permissible ac component of 1.5 Vpp (recommended filter capacitor 10 000 µF/40 Vdc).

Danger to internal components!

The internal fuses of the power supply assembly must be exchanged only by HEIDENHAIN personnel.

If the operating voltage of the control (5V on the processor board) is outside the limit values a blinking error message "PROCESSOR CHECK ERROR M" is displayed.

The buffer battery is the potential source for the RAM memory for NC programs, PLC programs and machine parameters when the control is switched off.

If the ”EXCHANGE BUFFER BATTERY” 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 Encoders

The HEIDENHAIN contouring controls are designed for the installation of incremental linear and angular encoders.

The control controls the actual position with a measuring step of 0.001 mm or 0.001°. Encoders with a graduation period of 0.001 mm or 0.001° to 1 mm or 1° may be used.

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

5.1 Linear encoders

Measurement of length is best performed by a linear 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 encoders:

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 Angle encoders

For direct angular measurement in the A, B or C axes the following incremental angle encoders 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.

The interface complies with the recommendations in VDE 0160, 5. 88 for separation from line power.

5.4.2 Connecting cable

Please use only HEIDENHAIN encoder cables, connectors and couplings.

In order to be able to connect an encoder to the square-wave signal input of the logic unit, the sinusoidal signal from the encoder 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 encoder or is 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).

HEIDENHAIN offers a connecting cable with a connector at one end (Id.-Nr. 244 006 ..).

The connecting cable to the nominal value outputs may not have more than one intermediate terminal clamp. The clamp 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.

11.5 PL 410 B / PL 410 PLC I/O unit

The PL 410 B / PL 410 has 64 PLC inputs, 31 PLC outputs and one "control-is-operational" output.

In its interface to the LE and its load capacity of inputs and outputs it is identical to the PL 400.

The analog inputs (X15 to X22) of the PL 410 cannot be evaluated in the LE 360 C! The DIL switch on the PCB of the PL 410 must therefore be set to OFF (as is stated on the housing). The PLC outputs are powered in groups and are therefore switched off via EMERGENCY STOP in groups.
