1. General information
The HEIDENHAIN TNC‘150 is equipped with an integral PLC: and is available in two basic versions:
HEIDENHAIN TNC 150 B
Control with a standard output to the machine interface.
The standard PLC program which is contained in the TNC 15C1almost corresponds to the interface for the
TNC 145 control version. Alterations to this interface are possible (if required, please ask for the PLC-Description
HEIDENHAIN TNC 150)
HEIDENHAIN TNC 150 Q
Control with a PLC-power board PL 100 B having
.63 inputs, 9 of which have fixed allocations,
.31 outputs
or with PLC-power board PL 110 B having
.63 inputs, 9 of which have fixed allocations
.25 outputs,
.3 bipolar output pairs
On delivery, this control version also has the standard PLCprogram stored.
By using a further PLC-power board PL 100 B or PL 110 B the PLC-inputs and outputs may be doubled.
Both control versions permit the connection of the visual display units BE 111 (9” screen) or BE 211
(12” screen).
Caution!
The description for the functioning of the interface being deal-: with pertains to the control versions
HEIDENHAIN TNC 150 B and HEIDENHAIN TNC 150 0. This is valid if the stored PLC-standard program has
not been altered prior tr) delivery.
Please note:
We are constantly working on the further development of our TNC-Controls and a certain control may deviate
from the versions described within this manual.

2.3 Transducers for TNC 150
23.1 Transducers for TNC 150 B / TNC 150 Q
The TNC 150 controls the actual position with a digital step of 0.001 mm and subdivides the grating period
of the transducers by 20 x or 10 x. Incremental linear transducers with a 20 urn or 10 urn grating pitch such as
.LS 107 (measuring lengths 240 mm to 3040 mm)
.LS 703 (measuring lengths 170 mm to 3040 mm)
.LS 903 (measuring lengths 70 mm to 1240 mm)
.LID 300,310
should therefore be used.
If accuracy requirements are permitting, indirect measuring :;ystems e.g. rotary encoders type ROD 450 or
ROD 456 may be connected to the drive spindles. The requj-ed number of lines for the encoder is calculated
as follows:
Line number / rev. = 50 x lead screw pitch (in mm) with 20 x evaluation (MP 12 - 15)
Line number / rev. = 100 x lead screw pitch (in mm) with 10 x evaluation (MP 12 - 15)
For angle measurement (with axis IV) rotary encoder types ?OD 250 and ROD 700 with 18.000 or
36.000 lines are available.
The cable length between transducer and TNC 150 must no1 exceed 20 m.

2.32 Transducers for TNC 150 BR / TNC 150 OR
For cable lengths between transducers and control which exceed 20 m or for transducers which exceed
3040 mm, the control versions TNC 150 BR / TNC 150 OR al-e used.
2.3.2.1 Transducers and EXE-units for the X, Y, Z-axes
Transducers for the main axes X, Y, Z are connected to the control via 3-axis EXE-units with separate voltage
supply.
The following combinations are available:

Rotary encoders may also be used instead of linear transducers. ’
The max. cable length between EXE 8 .. and TNC 150.R is 50 m and 20 m between the transducer and the
EXE. The total cable length is therefore 70 m.

In order to maintain the correct supply voltage, the total lengtl of the connecting cable between EXE 602
and the control is limited to 10 m.
When using an ROD 800 in conjunction with an EXE 602, an extension cable between EXE 602 and the control
should not be used.

The required push-buttons for “Stop” (opener) and “Start” as well as “rapid traverse” (closer) are incorporated
into the machine pendant or console by the machine tool manufacturer.
Depending on the programming of machine parameter 74, the function of the “rapid traverse” button overrides
all other programmed speeds i.e. on pressing the “rapid traverse” button, the machine moves in rapid traverse
regardless of any lower programmed feed rate.
It is left to the discretion of the machine tool manufacturer as to whether a “rapid traverse” button is to be
fitted. A “rapid traverse” can be programmed directly into the TNC 150 via keyboard-entry
(“rapid traverse” = 15999 mm/min or 6299 inch/min.)

routine according to the sequence programmed in parameter 59. The axis release relays remain permanently
closed after crossing the reference marks so that the machine is kept in a closed loop condition by the control.
Exception:
In all operating modes,the axis release contacts are opened by providing + 24 volts control voltage at input for
“Manual traverse” e.g. with traverse of machine in conventional mode with mechanical handwheels.
Caution !
Machines, on which axes could move out of position when the closed loop is off, must be fitted with a clamping
facility.

M-, S- and T-functions are provided statically via the same relay outputs of the control. To differentiate
whether an M-, S- or T-function is at the output, pulsed strobe signals “M-Strobe”, “S-Strobe” and “T-Strobe”
are used.

Please note:
The programmed time in machine parameter 121 must be less -:han the time in machine parameter 122.
The M-code is provided as a static signal. The impulse duration of the M-gating signal is programmed with
machine parameters 120 and 121. After duration of the time Fleriod programmed with 122, the control input
ist interrogated for the feedback signal: “Auxiliary function completed”. When this input is at + 24 V, the
M-code signals are inactiive and program run is resumed. If this input is inactive, (at 0 V), the M-code signals
are output and program run is interrupted until the input is re-activated (at 24 V).
The number of M-functiions depends of the type of decoding in the machine interface.
With external decoding, 100 different M-functions can be programmed.
Without external decodiing, 9 different M-functions can be programmed.
a) Coded M-functions
Output is in 8-4-2-l BCD-code, 2 decades parallel. (Decoded N-functions are present with the corresponding
coded M-functions simultaneously). The table on next page shows which M-functions are operative at the be-
ginning or end of a block, and the appropriate coding.

3.4.2 Output of S- and T-functions within Tool Call-block
The output of S- and/or T-functions with the gating signals can be either inhibited through relevant machine
parameters in the initial dialogue or programmed for output of an S-analogue voltage with up to 8 gear ratios,
Timing diagram
. Start,
l
S-Code, static
“Auxiliary function completed”
Please note:
The programmed time in machine parameter 121 must be less than the time in machine parameter 122.
3.4.2.1 Output of T-functions (tool numbers)
The T-Code is provided as a static signal. The impulse duration of the T-gating signal is determined by
machine parameters 120 and 121 (compare 3.4.1 Output of M-functions). After duration of the time period
programmed with 122, the control input is interrogated for the feedback signal: “Auxiliary function completed”
When this input is at + 24 V the T-code signals are cut-out and the program resumed. If the input is inactive
(at 0 V) the T-signals are output and program run is interrupted until the input is re-activated (at + 24 V).
The TNC 150 permits programming of tool numbers from 1 to 254. The tool numbers 1 - 99 in 8-4-2-KID-code
are only output in the programmed tool call blocks; for too numbers greater than 99, all 8 output-relays
pick-up. In addition to the tool number, the tool call block contains the data for the spindle speed S.
3.4.2.2 Output of S-functions (Spindle speeds)
Depending on how machine parameter 62 is program-med, the output of spindle speeds can be in S-Code or via
an analogue voltage output with up to 8 programmable gear ratios.
15

a) Coded output of S-functions (Spindle speeds)
The S-Code is provided as a static signal. The impulse duration of the S-gating signal is determined by
parameters 120 and 12’1 (compare 3.4.1 Output of M-functiors). After duration of the time period programmed
with 122, the control input is interrogated for the feedback signal: “Auxiliary function completed”. When this
input is at + 24 V the S-signal is cut-out and the program is resumed. If the input is inactive (at 0 V), the S-
signals are provided and the program run is interrupted until the input is re-activated (at + 24 V).
Spindle speeds are entered into the TOOL CALL program blocks with max. 4 digits in r:p.m. and automatically
rounded-off to the nearest standard speed by the control. The entered spindle speed is automatically coded by
the control in S-codes in accordance with German standard DIN 66025 page 3, in 100 steps - as listed on
next page (Output is in 2-decade BCD-code).
With the machine parameter 63 “RPM-Code”, the minimum and maximum permissible speed can be entered.
The RPM-steps can be set within the permissible RPM-range.
The code is entered as a 5 digit number:
1No. of I
min. RPM ,..
max. RPM ...
Step ............
decades S-Code No.
2 01-99
2 01-99
1 I- 9
Example:
The RPM-code “2 0 8 0 2” is entered,
i.e. the minimum spindle-RPM is therefore S 20 (1 RPM), the maximum spindle RPM is S 80 (1060 RPM), the
range is more closely defined by the specification that only every second speed is programmable.

The O-volt nominal value output must be grounded (see sectiol 3.13 Wiring). For activation of the spindle with
DC-servodrive, the control provides a DC voltage of 0 to + 10 volts. The polarity of the output voltage is
determined by parameter MPI 72. With the aid of machine parameters 78 to 85, up to 8 gear ratios may be
defined. This should be commenced with the entry of the ratio with the lowest speed. The max. voltage at the
input of the servo-amplifier which is programmed with machine parameter 8,7. The S-gating signal is provided
with each gear ratio.
After verification of the feedback signal “auxiliary function completed” and spindle status MO3 or M04, the
nominal value voltage with the ramp as programmed with maciine parameter 168 are output. No nominal value
voltage output takes place with M05.
The nominal value voltage for the spindle drive during gear change is determined with MP70. For the duration
of gear change, the polarity of this voltage MP70 is switched o>/er in accordance with parameters 124 and 125.
The control is fitted with an S-override potentiometer. The min. and max. voltage values can be programmed
with machine parameters (Nos. 86 to 89 and 184).

Important functions of the TNC 150 are under constant supenlision through self-diagnostics (electronic
subassemblies such as microprocessors, the memory read/write-store, positioning systems, transducers etc.). If
a fault is detected, it is indicated as a flashing display in the plain language dialogue. On output of fault-
indication, the “emergency stop” contact opens.
The “Emergency Stop” condition of TNC 150 can only be carcelled by switching off the mains voltage-provided
that the fault has been rectified. A special mains switch may be necessary for the control only!
The emergency stop contact must cut-out the 24 V auxiliary voltage in the machine interface. Due to the
significance of the emergency stop contact for safety reasons, its function is monitored by the control with each
switch-on of power (see flow chart).
18

The emergency stop contact can be governed’ by two monoflops:
.Monoflop for the position loop calculator
.Monoflop for the main calculator
Both directions of the emergency stop circuit are checked when the control is switched on (see
flow-chart).
