# ID 21758

Maximum difference of radii exceeded.
Description | When programming circles G02, G03 with inactive circle centre point correction (G164), it may occur that the calculated radius of circle start point and circle end point are varying. The resulting radius difference should not exceed maximum permissible radius difference limit.

This limit value for the radius difference can be set via parameters P-CHAN-00171 and P-CHAN-00172.

Response | Class | 2 | Program execution stop.
Solution | Class | 3 | Correction of programmed circle end point in CNC program.
Parameter | %1: | Error value [0.1 µm or 0.0001°]
Current radius difference of circle start point and circle end point.
%2: | Upper limit value [0.1 µm or 0.0001°]
Maximum permissible radius difference
%3: | Current value [0.1 µm or 0.0001°]
Circle start radius
%4: | Current value [0.1 µm or 0.0001°]
Circle end radius
Error type | 1, Error message from NC program.
