Technical notes
Notations

The following notations and abbreviations are used in this Documentation:
S PLC interface signals -> IS ”Signal name” (signal data)
Example: IS ”Feed override“ (VB380x 0000)
The variable byte is in the range “at axis“, “x” stands for the axis: 0 axis 1
1 aixs 2
n axis n+1.
S Machine data -> MD MD_NR: MD_NAME
S Setting data -> SD SD_NR: SD_NAME
S The headlines of the individual chapters/sections are added by a code designation in brak-
kets (e.g. Chapter 1: EMERGENCY STOP (N2)). This code designation is used in referen-
ces to individual Chapters/Sections.
Explanation of the code designations
In the chapters/sections of each Description of Functions, the data and/or signals are explai-
ned which are important for the function discussed. Within these explanations provided in the
form of tables, some terms and abbreviations are used, which are explained here.
Default value:
This is the default value of the machine/setting data when loading the standard machine data.
Range of values (minimum/maximum values):
specifies the input limits. If no range of values is specified, the data type defines the input li-
mits, and the field is marked with ”***”.

Activation of changes:
Changes in machine data, setting data or the like come not immediately into effect in the con-
trol system. The conditions for activation are therefore always specified. The possibilities used
are listed below by their priority:
S POWER ON (po) Turning off/turning on the power supply
or softkey “StartUp/Normal” on HMI

S NEW_CONF (cf) ”RESET” key on the control unit
S RESET (re) ”RESET” key on the control unit
S immediately (im) after input of a value
Protection level:
There are the protection levels 0 to 7 whereby the interlock for protection levels 1 to 3 can be
canceled by setting a password and the interlock for protection levels 4 to 7 via the IS “Protec-
tion level” (e.g.: keyswitch position). Protection level 0 cannot be accessed (see Chapter “Va-
rious Interface Signals”).
The operator has only access to information that corresponds to this particular protection level
and the lower protection levels. The machine data are assigned different protection levels by
default and are marked by a Write/Read value (e.g. 4/7).
Note: In this document, the machine and setting data of protection levels 2 to 7 are documen-
ted. Notes on machine data of protection level 1 are only provided in special cases (expert
mode).
Unit:
The unit refers to the default setting (see Section “Velocities, Setpoint/Actual Value System,
Closed-Loop Control“).
If the MD has no physical unit as the basis, the field is marked with ”-”.
Data type:
The following data types are used in the control system:
S DOUBLE
Floating point value (64-bit value )
Input limits from +/-4.19*10
-307

to +/-1.67*10
308
S DWORD
Integer values (32-bit value)
Input limits from -2 147 483 648 to +2 147 483 648 (decimal),

as a hexadecimal value: 0000 to FFFF
S BYTE
Integer values (8-bit value)
Input limits from -128 to +127 (decimal), as a hexadecimal value: 00 to FF
S BOOLEAN
Boolean value: TRUE (1) or FALSE (0)
S STRING
consisting of a maximum of 16 ASCII characters (uppercase letters, digits and underscore)

EMERGENCY STOP (N2)
1.1 Brief description
Important
We would like to draw the machine manufacturer’s attention to his duty to observe the rele-
vant international and national standards (see notes on standards further below in the text).
The SINUMERIK 802D supports the machine manufacturer in implementing the EMER-
GENCY STOP function according to the specifications in this Description of Functions. The
EMERGENCY STOP function (tripping, sequence and acknowledgement) is the sole and only
responsibility of the machine manufacturer.
Note
The following standards are relevant for the EMERGENCY STOP function:
S
EN 292 Part 1
S
EN 292 Part 2
S
EN 418
S
EN 60204 Part 1:1992 Section 10.7
The VDE 0113 Part 1 is only valid for a transition period and is replaced by EN 60204.
EMERGENCY STOP in the control system
The following arrangements are provided in the control system to support the machine manu-
facturer in implementing the EMERGENCY STOP function:
S Initiation of the EMERGENCY STOP sequence in the NC via the PLC input.
S The EMERGENCY STOP sequence in the NC will decelerate all axes and spindles in the
NC as fast as possible.
S The EMERGENCY STOP status cannot be canceled by unlocking the EMERGENCY

STOP button. Resetting the control device will not result in a restart.
S After the EMERGENCY STOP status has been canceled, it is not necessary to reference
axes or synchronize spindles (the positions are corrected).
EMERGENCY STOP button
A mushroom button (with one normally closed and normally open contact each), further refer-
red to as EMERGENCY STOP button, is installed in the Siemens machine control panel
(MCP) for the 802D.

1.2 EMERGENCY STOP sequence
Prerequisite
The actuation of the EMERGENCY STOP button or a signal directly derived from it must be
carried to the control (PLC) as a PLC input. In the PLC user program, this PLC input must be
passed on to the NC to the IS ”EMERGENCY STOP“ (V2600 0000.1).
Resetting of the EMERGENCY STOP button or a signal directly derived from it must be car-
ried to the control (PLC) as a PLC input. In the PLC user program, this PLC input must be
passed on the NC to the IS “Acknowledge EMERGENCY STOP” (V2600 0000.2).
Sequence in the NC
In the control system, the predetermined sequence (as per EN 418) of internal functions for
the EMERGENCY STOP status is as follows:
1. The part program execution is interrupted. All axes and spindles are stopped along defined
braking ramps according to MD 36610: AX_EMERGENCY_STOP_TIME.
2. The IS ”802-READY” (V3100 0000.3) is reset.
3. The IS ”EMERGENCY STOP active” (V2700 0000.1) is set.
4. Alarm 3000 is set.
5. The servo enable is disabled after an axis/spindle-specific time that can be set in MD

36620: SERVO_DISABLE_DELAY_TIME (servo enable cutout delay) has been elapsed.
In this context, make sure that 36620: SERVO_DISABLE_DELAY_TIME must be specified
at least as large as MD 36610: AX_EMERGENCY_STOP_TIME.
Sequence on the machine
The EMERGENCY STOP sequence on the machine is exclusively defined by the machine
manufacturer. The following must be observed in conjunction with the sequence in the NC:
S The sequence in the NC is started using the IS ”EMERGENCY STOP“ (V2600 0000.1).
After the axes and spindles have been stopped, the power supply must be interrupted acc.
to EN418.
S The sequence in the NC has no influence on the PLC I/Os (digital outputs). If you wish
individual outputs to have a certain status in case of EMERGENCY STOP, the machine
manufacturer must implement the appropriate functions in the PLC program.
Important
To interrupt the power supply, is the sole and only responsibility of the machine manufacturer.
If you wish the sequence in the NC in case of EMERGENCY STOP not to be carried out as
defined, the IS “EMERGENCY STOP” (V2600 0000.1) may not be set until an EMERGENCY
STOP status defined by the machine manufacturer in the PLC user program is reached. Until
the IS “EMERGENCY STOP” is not yet set and no other alarm is pending, all IS are active in
the NC. Thus, any manufacturer-specific EMERGENCY STOP status is possible.

1.3 EMERGENCY STOP acknowlededgement
Acknowledging EMERGENCY STOP
The EMERGENCY STOP status will only be reset if first the IS “Acknowledge EMERGENCY
STOP” (V2600 0000.2) and then the IS “Reset” (V3000 0000.7) is set. When doing so, make
sure that the IS ”Acknowledge EMERGENCY STOP” and the IS ”Reset” must be set together
at least as long as the IS “EMERGENCY STOP active” (V2700 0000.1) has been reset (see

Fig. 1-1).

PLC I/Os

The PLC I/Os must be brought again by the PLC user program to the appropriate status requi-
red to operate the machine.

Axis-specific machine data
36620 SERVO_DISABLE_DELAY_TIME
MD number Servo enable cutout delay
Default: 0.1 Min. input limit: 0.02 Max. input limit: ***
Change valid after NEW_CONF Protection level: 2/2 Unit: s
Data type: DOUBLE Valid from SW release:
Meaning: Maximum time delay for cancellation of “Servo enable” after faults.
The speed enable (servo enable) of the drive is canceled internally in the control system at the
latest after a set delay time if the axis / spindle is moving.
The entered delay time acts due to the following events:
S in case of errors resulting in immediate axis stop
S if the IS “Servo enable” is canceled from the PLC.
Once the actual speed reaches the zero speed range (MD 36060: STANDSTILL_VELO_ TOL),
“Servo enable” is disabled for the drive.
The time should be set as large as the axis / spindle needs to come to a standstill from maximum
traversing velocity or speed.

If the axis / spindle is already at a standstill, “Servo enable” is disabled for the drive immediately.
Application example(s) The speed control of the drive should be maintained for this time to make sure that the axis/spindle
can come to a standstill from maximum traversing velocity or speed. For this time, the cancellation
of “Servo enable” should be delayed for an axis/spindle moving.
Special cases, errors, ...... CAUTION: If the servo enable cutout delay is set too small, the “Servo enable” is already canceled
even if the axis/spindle is still traversing. In this case, it is suddenly stopped with setpoint 0.
The time set in this MD should therefore be greater than the time of the braking ramp in case of
error statuses (MD 36610: AX_EMERGENCY_STOP_TIME).

2.2.1 Contour monitoring
Function
The principle of functioning of the contour monitoring is based on the permanent comparison
of measured actual position value and the actual position value calculated from the NC posi-
tion setpoint. To calculate the following error in advance, a model is used which simulates the
dynamic properties of the position control including feedforward control.
To make sure that the monitoring system does not respond already in the case of slight
speed variations (caused by load changes), a tolerance band is permitted for the maximum
contour deviation.
If the permissible actual value deviation entered in MD 36400: CONTOUR_TOL (contour mo-
nitoring tolerance band) is exceeded, an alarm is output, and the axes are stopped.
Activation
The contour monitoring is active for axes and a position-controlled spindle.
Effect
If the contour error is too large, the following will occur:
S Alarm 25050 ”Contour monitoring” is output.
S The axis/spindle concerned is stopped with rapid stop (with open position feedback loop)
via a speed setpoint ramp.
The duration of the braking ramp is defined in the MD 36610: AX_EMER-
GENCY_STOP_TIME (duration of braking ramp in case of error statuses).

S If the axis/spindle interpolates with other axes/spindles, these are stopped by rapid stop
with reduction of the following error (position setpoint = constant).
Remedy
S Increase tolerance band of monitoring function in MD 36400.
S The real servo gain factor must correspond to the desired servo gain factor set in
MD 32200: POSCTRL_GAIN (servo gain factor).
With an analog spindle, check
MD 32260: RATED_VELO (rated motor speed) and
MD 32250: RATED_OUTVAL (rated output voltage).
S Check optimization of speed controller.
S Check smooth running of axes.
S Check machine data for traversing movements (feedoverride, acceleration, max. veloci-
ties, ... )
