An alarm message is issued if the difference between the circle radii is either
- greater than the value in the MD21000 $MC_CIRCLE_ERROR_CONST (for small radii, if the programmed radius is
smaller than the quotient of the machine data MD21000 $MC_CIRCLE_ERROR_CONST divided by MD21010
$MC_CIRCLE_ERROR_FACTOR), or
- greater than the programmed radius multiplied by the MD21000 $MC_CIRCLE_ERROR_FACTOR (for large radii,
if the programmed radius is greater than the quotient of the machine data MD21010 $MC_CIRCLE_ERROR_CONST
divided by MD21010 $MC_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 MD21000 $MC_CIRCLE_ERROR_CONST and MD21010 $MC_CIRCLE_ERROR_FACTOR. If the values 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 Clear alarm with NC START or RESET key and continue the program.
Continuation:
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 revolutions 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: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
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, an inadmissible number of full revolutions has been specified.
The number of revolutions must not be negative and must not be greater than 1000000.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Clear alarm with the RESET key. Restart part program
Continuation:
14050 [Channel %1: ] Block %2 nesting depth for arithmetic operations exceeded
Parameters: %1 = Channel number
%2 = Block number, label
