Pasos oficiales de solución de problemas

Parameters: %1 = Channel number %2 = Block number, label Definitions: When programming a circle by means of an intermedia te point (CIP) all 3 points (initial, end and intermediate points) are on a straight line and the interm ediate point (programmed by means of interpolation parameters I, J, K) is not located between the initial and end points. If the circle is the component of a helix, the specif ied number of turns (keyword TURN=...) determines further block processing: - TURN>0: alarm display because the ci rcle radius is infinitely great. - TURN=0 and CIP specified between initial and end points. A straight line is generated between the initial and end points (without alarm message). Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: Locate the position of the intermediate point with the parameters I, J and K in such a way that it actually is located between the initial and end points of the circle or do not make use of this type of circle programming and instead program the circle with r adius or opening angle or center point parameters. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
