Max. execution time of realtime cycles (P-CHAN-00425)
P-CHAN-00425 | Max. execution time of realtime cycles per CNC cycle |
Description | This parameter defines the maximum execution time of realtime cycles in the NC channel. The parameter is specified in percent (%) and refers to the length of the CNC cycle. Example: If the realtime task of the CNC is clocked at 2ms and parameter P-CHAN-00425 is 75, the realtime cycles may require a total execution time of maximum 1.5ms. If this time is exceeded, error ID 50939 is output. |
Parameter | rt_cycles.max_duration |
Data type | UNS16 |
Data range | 0 < P-CHAN-00425 < MAX_UNS16 |
Dimension | % |
Default value | 75 |
Remarks | The user has no restrictions regarding the number of instructions within a realtime cycle. Realtime timeouts will occur if realtime cycles contain too many instructions and cannot be executed in one CNC cycle,
The parameters P-CHAN-00426 and P-CHAN-00427 represent a safety mechanism to prevent such realtime timeouts as early as possible. |
