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.
