In circle radius programming the starting and end points are identical, thus the circleposition is not determined by starting and end points.2. Radii: The NCK calculates from the present start point and the other programmed circleparameters the radii for the start and the end point.An alarm message is issued if the difference between the circle radii is either• greater than the value in the MD 21000 CIRCLE_ERROR_CONST (for small radii, if theprogrammed radius is smaller than the quotient of the machine dataCIRCLE_ERROR_CONST divided by 21010 CIRCLE_ERROR_FACTOR), or• greater than the programmed radius multiplied by the MD CIRCLE_ERROR_FACTOR(for large radii, if the programmed radius is greater than the quotient of the machinedata CIRCLE_ERROR_CONST divided by CIRCLE_ERROR_FACTOR).3. Center points: A new circle center is calculated using the circle radius at the startingposition. It lies on the mid-perpendicular positioned on the connecting straight line fromthe starting point to the end point of the circle. The angle in the radian measure betweenboth straight lines from the starting point to the center calculated/programmed as suchmust be lower than the root of 0.001 (corresponding to approx. 1.8 degrees).Reactions: - Alarm display.- Interface signals are set.- Correction block is reorganized.Remedy: Please inform the authorized personnel/service department. Check MD 21000CIRCLE_ERROR_CONST and 21010 CIRCLE_ERROR_FACTOR. If the values arewithin reasonable limits, the circle end point or the circle mid-point of the part programblock must be programmed with greater accuracy.Program Continuation: Clear alarm with NC START or RESET key and continue the program.14045 Channel %1 block %2 error in tangential circle programmingParameters: %1 = Channel number%2 = Block number, labelDefinitions: The alarm may have the following causes:The tangent direction is not defined for tangent circle, e.g. because no other travel blockhas been programmed before the current block. No circle can be formed from start andend point as well as tangent direction because - seen from the start point - the end point islocated in the opposite direction to that indicated by the tangent.It is not possible to form a tangent circle since the tangent is located perpendicular to theactive plane.In the special case in which the tangent circle changes to a straight line, several completecircular revolutions were programmed with TURN.Reactions: - Local alarm reaction.- Alarm display.- Interface signals are set.- Correction block is reorganized.- NC Stop on alarm at block end.
