14040 Channel %1 block %2 error in end point of circle

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: In circular interpolation, either the circle radii for the initial point and the end point are further apart, or

the circle center points are further apart, than specified in the machine data.

1. In circle radius programming the starting and end points are identical, thus the circle position is not

determined by starting and end points.

2. Radii: The NC calculates from the present start point and the other programmed circle parameters

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 the pro-

grammed radius is smaller than the quotient of the MD 21000 CIRCLE_ERROR_CONST divided by

MD 21010 CIRCLE_ERROR_FACTOR), or

• greater than the programmed radius multiplied by the MD 21010 CIRCLE_ERROR_FACTOR (for

large radii, if the programmed radius is greater than the quotient of the MD 21000

CIRCLE_ERROR_CONST divided by MD 21010 CIRCLE_ERROR_FACTOR).

3. Center points: A new circle center is calculated using the circle radius at the starting position. It lies

on the mid-perpendicular positioned on the connecting straight line from the starting point to the end

point of the circle. The angle in the radian measure between both straight lines from the starting point

to the center calculated/programmed as such must be lower than the root of 0.001 (corresponding to

approx. 1.8 degrees).

Reaction: Correction block is reorganized.

Interface signals are set.

Alarm display.

Remedy: Please inform the authorized personnel/service department.

Check MD 21000 CIRCLE_ERROR_CONST and MD 21010 CIRCLE_ERROR_FACTOR. If the val-

ues are within reasonable limits, the circle end point or the circle mid-point of the part program block

must be programmed with greater accuracy.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

14045 Channel %1 block %2 error in tangential circle programming

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: The alarm may have the following causes:

The tangent direction is not defined for tangent circle, e.g. because no other travel block has been

programmed before the current block.

No circle can be formed from start and end point as well as tangent direction because - seen from the

start point - the end point is located 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 the active plane.

In the special case in which the tangent circle changes to a straight line, several complete circular rev-

olutions were programmed with TURN.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Change part program.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

14048 Channel %1 block %2 wrong number of revolutions in circle

programming

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: In the circle programming, a negative number of full revolutions has been specified.

Reaction: Interpreter stop

NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: Change part program
