The TNC therefore cannot show the complete tree structure of the program within smarT.NC, nor can you test or run the program.  Rotational speed of the housing fan is too low.  Reentrance into smarT.NC is at present not possible.  The program that you selected cannot be processed by the TNC because it has too many units.  The 3,3-V power supply of the control is too high.  The 3,3-V power supply of the control is too low.  Error in the conversion of the programmed workpiece blank in the FK graphics: One edge length is negative (min. and max. limits were switched).  FK programming: A tangential FK block (FLT,FCT) can follow a conventional positioning block only if the approach direction is unambiguously defined.  FK programming: You programmed a relative angle reference to a part program block whose slope angle is not constant.  FK programming: In FPOL you did not program both coordinates of the working plane.   You defined the cutter radius for the active tool in the tool table as less than or equal to 0.  More than 5 axes were defined for PLC positioning in one positioning block, but the TNC can move no more than 5 axes simultaneously.  You tried to run Cycle 254 with the slot position 0 (Q367=0) in conjunction with the point pattern Cycle 221.  In the first block of a subprogram, you did not defined both coordinates of the working plane.  You tried to download a program with over 100 NC blocks into the demo version of the iTNC 530 programming station.  No symbolic operands are being used in the PLC program.  You tried to change a preset value in an active tool-axis system.  You tried to set a datum although the M114 function is active.  An attempt was made to activate a function that requires a running PLC program.  Not all tests were completely run.  The CRC sum of the compiled PLC program is incorrect.  General file management error.  General software error in the main processor task.  Insufficient memory left free to open a machine parameter file.  Internal error: incorrect interrupt  Internal error: A task was given an unknown command or a command with illegal parameters.  You have attempted to simultaneously move more axes than is possible with the export version of the control.  The CRC sum of the EPROMs IC-P1 and IC-P2 is incorrect.  The CRC sums of the EPROMs IC-P3 and IC-P46 is incorrect.  The axis is moving at least 4 times slower or faster than commanded by the nominal speed command output.  The motor is moving while the axis slide is not, or vice versa.  You did not enter the end-of-block character in the given line of the format description file.  You entered more than 32 keywords in the given line of the format description file.  You defined an unknown keyword in the given line of the format description file.  You used an unknown statement in the given line of the format description file.  You used an invalid format statement in the given line of the format description file.  You did not close the format description in the given line of the format description file.  You defined an excessively long keyword in the given line of the format description file.  In the given line of the format description file, you defined a keyword that requires the entry of an index although no index had been defined.  In the given line of the format description file you did not define a closing bracket (]) after a keyword with an index.  The mask file that you defined could not be opened.  The TNC cannot make the output file: - Output file is selected in the Programming and Editing mode. - The destination directory does not exist.  Two collision-monitored objects have come below a certain minimum clearance. |<-->| Warning - coarse clearance |<->| Warning - fine clearance  The machine was moved into a collision-protected area. Further movement would result in a collision. |<>| Collision protection prevents further movement of the axes.  The Profibus firmware on the Profibus master could not be updated.  The file entered in OEM.SYS under "MPFRAGMENTFILE =" cannot be opened:  You tried to use the FN17 function to write a value that lies outside of the permitted input range.  You tried to change the TNC network settings although DHCP is active (Dynamic Host Configuration Protocol, dynamic IP address assignment).  You pressed the RESET COLUMN soft key.  You defined a fixed cycle with the depth 0.  You tried to use a workpiece blank definition from an .hu program, but you did not select the current contour program from an .hu program.  You tried to insert a block from the clipboard, but the clipboard is empty.  - Inverter defective - Incorrect wiring of the braking control (short circuit to 0 V, short circuit to 24 V)  - Inverter defective - Incorrect wiring of the braking control (short circuit to 0 V, short circuit to 24 V)  The actual speed of the spindle varies too greatly from the programmed nominal speed.  - You connected to the USB bus a device that the TNC does not support. - You have a software version that does not support USB block devices (memory sticks, hard disks, CD-ROM drives).  You tried to edit a unit although the marking function is active.  You used FEZ to define a feed rate without having defined the number of teeth for the active tool.  You tried to activate the M118 function during active collision monitoring.  You tried to edit a point table with the .PNT file type.  During M128 or TCPM FUNCTION, the tolerance of the standstill monitor (MP1110.x) of an open-loop axis (displayed only) was exceeded. Maybe you tried to position this axis manually.  An error occurred during automatic generation of the cycle structure. Working with touch-probe and/or machining cycles is not or not entirely possible.  You tried to use a feature that is not enabled on your TNC by the Feature Content Level (FCL) management.  You tried to use a software option that is not enabled on your TNC.  You tried to open a DXF file that cannot be edited by the TNC.  The TNC locks keys during a status change, but the lock was opened because the status change was not completed within 15 seconds.  You tried to use a feature that is not available on your machine.  You tried to select a file that is editable only in the smarT.NC operating mode.  In an inch program you combined the FU functions (feed rate in in./rev) or FZ (feed rate in in./tooth) with the M136 function (feed rate in 0.1 in./rev).  You tried to select the smarT.NC operating mode although the cycle structure is not correctly set.  In the PATTERN DEF block, you programmed the first position with incremental coordinates.  You tried to switch on the touch probe cycle 441 to switch on the angle tracking, although this function is deactivated by machine parameter 6165.  During the switch-off test the CC performs a current measurement started by the MC. If there is no reaction after max. 2 s, it results in a Stop0 reaction.  Software error  Software error  One or more machine keys that are connected with "MT" (machine key) are active on the CC side.  Machine-key permissive key is depressed on the MC side.  Machine-key permissive key is depressed on the CC side.  Handwheel permissive key is active on CC side.  Tool changer permissive key is active on CC side.  One or more protective doors (A/S/T) of the CC are open.  Internal calculations in combination with the Scaling Factor or Axis-Specific Scaling Factor cycles resulted in an impermissibly large numerical value.  The cycle can only run in negative direction (positive in Cycle 204) because the machine parameter "suppressDepthErr" is set to on.  - You tried to move the tool with the "virtual tool axis." The definition for the tool axis does not exist or was canceled.  You have hidden or disabled a point for which a pre-positioning height is defined. In some cases this could lead to a collision.  Permissive button of machine operating panel or handwheel is depressed.  Permissive button of machine operating panel or handwheel is depressed.  You tried to convert a program containing an ISO program call.  You defined the range definition in Cycle 30 (DIN/ISO: G60) incorrectly.  You tried to select a datum number by soft key although no datum table is selected in the program header.  The iTNC cannot simulate the M140 MB MAX function because the working space monitoring is inactive.  You have connected several string variables and, in doing so, have exceeded the maximum permissible string length.  In a TOOL CALL or TOOL DEF block you tried to define a tool number although it is prohibited by machine parameter.  In a TOOL CALL or TOOL DEF block you tried to define a tool name although it is prohibited by machine parameter.  You tried to divide by 0.  You tried to calculate the root of a negative number.  You tried to calculate the logarithm of a negative number.  You tried to form the tangent of a 90° angle (or its integral multiple).  In Cycle 22 (ISO: G122), you tried to define the feed-rate factor Q401 to be less than 1. This upgrade feature is locked on your TNC by the FCL management.  In a formula calculation the absolute value of the argument is greater than 1.  In a formula calculation the absolute value of the argument is greater than 1.  You tried to edit the active preset although M128 or the TCPM FUNCTION is active.  - No cutting data tables available in the TNC:\ directory - No workpiece material defined by WMAT block - No tool material defined in TOOL.T - No cutting data table defined in TOOL.T - Combination of workpiece and tool material not available in the active cutting data table  A service/support file listed in OEM.SYS is faulty or missing.  Someone tried to set a breakpoint through the data interface.  You did not define a probing direction in probe cycle 4.  You entered a spindle speed S greater than the maximum speed defined for this tool in the tool table TOOL.T.  You tried to rename an entire drive.  You tried to copy an entire drive.  You tried to delete an entire drive.  You tried to open a file that cannot be processed by the TNC.  - Defective hardware - Spindle cannot be controlled  Axes cannot be controlled  During an active FUNCTION TCPM, AXIS SPAT function, you tried to resume a program by using the GOTO block number key.  In the TOOL CALL block(DIN/ISO: T block) you programmed a tool axis that was locked for the currently active kinematics by your machine tool builder.  Traverse in safe mode through TNCopt exceeded the permissible range.  Settings for the PLC memory layout have changed.  Your hardware does not have enough main memory to start the help system.  You used function M141 (suppress touch-probe monitor) while the collision monitor was active.  A reference run was started in one axis by PLC module, then the M function was acknowledged before the reference run could finish. As a result the NC program cannot continue.  - Controller unit with operator safety module is not supported with the installed software  Hardware is defective  Although SH1B.x=1, RDY.x=0  Although SH1B.x=0, RDY.x=1  The entered values could not be transferred due to an internal error.  You tried to swap a linear axis for a rotary axis.  When swapping axes, you tried to assign two different axes to the same axis.  When swapping axes, you tried to swap an axis for an axis that does not exist.  In the global program settings you defined a value that lies outside of the permitted input range.  You tried to change the global program settings while the program was running.  There has been an indefinable error.  There was a spindle overload during adaptive feed rate control.  The amplitude of the position encoder signal is too high or the signal for contamination is active.  The amplitude of the position encoder signal is too low or the signal for contamination is active.  The maximum input frequency was exceeded at a position encoder input.  Contradiction apparent from comparison of the absolute and incremental positions.  In the PLANE AXIAL function you defined a rotary axis that is not described in the active kinematics.  MC did not command a braking test although MP2230.x !=0 (i.e., run brake test in this axis).  There is an error in the column definition in a freely definable table: - Column name missing - Field width not allowed - Number of decimal places not allowed - Unknown column type  - The actual speed of the spindle is too much higher than the programmed nominal speed.  In the smarT.NC operating mode you selected the Program Run submode although global program settings were active.  You tried in the smarT.NC operating mode to open a file that it cannot depict.  - You tried to edit a program that is now being run. - You tried to edit a table that is accessed from within the program that is now being run.  An attempt was made to run an NC macro while the machine status was being restored.  - Poor resolution of the absolute value from the ENDAT encoder.
