Sinumerik Alarm 4065 Buffered memory was restored from backup medium (potential loss of data!)
Definitions:
Only occurs with PC-NC. A possible data integrity error was detected in the buffered memory during power-up.The buffered memory was initialized with the last backup copy. Changes in the buffered memory, which have been made since the last backup copy update, have been lost. Backup copies of the buffered memory are updated (on the hard disk) every time the control is shut down normally.
!! Only for 802D: The reason for this procedure is that the backup time is exceeded. Make sure that the required operating time of the control corresponds to the specifications in your Installation & Start-up Guide. The current backup copy of the buffered memory has been created by the last internal data backup via the “Save data” soft key on the HMI.
Reactions:
– Alarm display.
– Interface signals are set.
– NC not ready.
– NC Start disable in this channel.
Remedy:
Start the control again.
Program Continuation:
Switch control OFF – ON.

Re: NEED HELP 828D alarm 4065
Please help me for remove 4065 alarm in 828d
Здравствуйте уважаемые! На вертикально — фрезерном станке высветилась ошибка 004065 Буферизация памяти восстановлено с жесткого диска.
Произошла она в результате вытаскивания провода внутри стойки, который подходит к нижней клавиатуре. Эту операцию мы делали, из -за того, что при работе станка клавиатура, постоянно зависала. Сегодня произошла перезагрузка станка с ошибкой 004065. Ошибка не сбрасывалась кнопкой Reset, После того, когда я его снова перезагрузил, она исчезла, но в программе я не могу редактировать текст, Пишет запись защищена. Как решать данную проблему??

Fundamental Geometrical Principles Workpiece positions 1.1.1 Workpiece coordinate systems In order that the machine or the control can work with the positions specified in the NC program, these specifications have to be made in a reference system that can be transferred to the directions of motion of the machine axes.
- Page 14
Fundamental Geometrical Principles 1.1 Workpiece positions Figure 1-2 Workpiece coordinate system for turning The workpiece zero (W) is the origin of the workpiece coordinate system. Sometimes it is advisable or even necessary to work with negative position specifications. For this reason, positions that are to the left of the zero point are assigned a negative sign («-«). -
Page 15: Cartesian Coordinates
Fundamental Geometrical Principles 1.1 Workpiece positions 1.1.2 Cartesian coordinates The axes in the coordinate system are assigned dimensions. In this way, it is possible to clearly describe every point in the coordinate system and therefore every workpiece position through the direction (X, Y and Z) and three numerical values The workpiece zero always has the coordinates X0, Y0, and Z0.

Page 18: Polar Coordinates
Fundamental Geometrical Principles 1.1 Workpiece positions 1.1.3 Polar coordinates Polar coordinates can be used instead of Cartesian coordinates to describe workpiece positions. This is useful when a workpiece or part of a workpiece has been dimensioned with radius and angle. The point from which the dimensioning starts is called the «pole». Position specifications in the form of polar coordinates Polar coordinates are made up of the polar radius and the polar angle.

Page 23: Working Planes
Fundamental Geometrical Principles 1.2 Working planes Working planes An NC program must contain information about the plane in which the work is to be performed. Only then can the control unit calculate the correct tool offsets during the execution of the NC program. The specification of the working plane is also relevant for certain types of circular-path programming and polar coordinates.

Page 67: Tool Offsets
Tool offsets General information about the tool offsets Workpiece dimensions are programmed directly (e.g. according to the production drawing). Therefore, tool data such as milling tool diameter, cutting edge position of the turning tool (counterclockwise/clockwise turning tool) and tool length does not have to be taken into consideration when creating the program.
-
Page 68: Tool Length Compensation
Tool offsets 5.2 Tool length compensation Tool length compensation The tool length compensation compensates for the differences in length between the tools used. The tool length is the distance between the toolholder reference point and the tool tip: This length is measured and entered in the tool compensation memory of the control together with definable wear values.

Page 69: Tool Radius Compensation
Tool offsets 5.3 Tool radius compensation Tool radius compensation The contour and tool path are not identical. The milling tool or cutting edge center must travel along a path that is equidistant from the contour. To do this, the control requires data about the tool form (radius) from the tool compensation memory.

Glossary Interpolatory compensation Interpolatory compensation is a tool that enables manufacturing-related leadscrew error and measuring system error compensations (SSFK, MSFK). Interrupt routine Interrupt routines are special → subroutines that can be started by events (external signals) in the machining process. A part program block which is currently being worked through is interrupted and the position of the axes at the point of interruption is automatically saved. - Page 590
Glossary Limit speed Maximum/minimum (spindle) speed: The maximum speed of a spindle can be limited by specifying machine data, the → PLC or → setting data. Linear axis In contrast to a rotary axis, a linear axis describes a straight line. Linear interpolation The tool travels along a straight line to the destination point while machining the workpiece. - Page 591

Glossary Numerical Control: Numerical control (NC) includes all components of machine tool control: → NCK, → PLC, HMI, → COM. Note A more correct term for SINUMERIK 840D controls would be: Computerized Numerical Control Numerical Control Kernel: Component of NC that executes the → part programs and basically coordinates the motion operations for the machine tool. - Page 593
Glossary Oriented tool retraction : If machining is interrupted (e.g. when a tool breaks), a program command can be RETTOOL used to retract the tool in a user-specified orientation by a defined distance. Overall reset In the event of an overall reset, the following memories of the → CPU are deleted: ●… - Page 594
Glossary PCIN data transfer program PCIN is an auxiliary program for sending and receiving CNC user data (e.g. part programs, tool offsets, etc.) via a serial interface. The PCIN program can run in MS-DOS on standard industrial PCs. Peripheral module I/O modules represent the link between the CPU and the process. - Page 595
Glossary Pre-coincidence Block change occurs already when the path distance approaches an amount equal to a specifiable delta of the end position. Program block Program blocks contain the main program and subroutines of → part programs. Programmable frames Programmable → frames enable dynamic definition of new coordinate system output points while the part program is being executed. - Page 596
Glossary Rapid traverse The highest traverse rate of an axis. For example, rapid traverse is used when the tool approaches the → workpiece contour from a resting position or when the tool is retracted from the workpiece contour. The rapid traverse velocity is set on a machine-specific basis using a machine data element. - Page 597
Glossary Setting data Data, which communicates the properties of the machine tool to the NC, as defined by the system software. Softkey A key, whose name appears on an area of the screen. The choice of soft keys displayed is dynamically adapted to the operating situation. - Page 598
Glossary Synchronized Actions 1. Auxiliary function output During workpiece machining, technological functions (→ auxiliary functions) can be output from the CNC program to the PLC. For example, these auxiliary functions are used to control additional equipment for the machine tool, such as quills, grabbers, clamping chucks, etc. - Page 599
Glossary TOA area The TOA area includes all tool and magazine data. By default, this area coincides with the → channel area with regard to the reach of the data. However, machine data can be used to specify that multiple channels share one → TOA unit so that common tool management data is then available to these channels. - Page 600
Glossary User memory All programs and data, such as part programs, subroutines, comments, tool offsets, and zero offsets/frames, as well as channel and program user data, can be stored in the shared CNC user memory. User Program User programs for the S7-300 automation systems are created using the programming language STEP 7. - Page 601
