Sampling of override (P-CHAN-00065)

P-CHAN-00065

Override scanning

Description

To avoid exciting oscillations in the machine, the override value is only adopted after the first change to calculate a new velocity. This may also occur in the same cycle.

The next value is only adopted after the time expires in the parameter. This avoids excitations in the machine caused by an override change.

Parameter

override_delay

Data type

UNS32

Data range

10 * cycle time < override_delay < 100 s

Dimension

µs

Default value

10

Remarks

Parameterisation example: The delay time for override scanning is set to 50 ms.

override_delay     50000

The smallest value that can be set in override_delay is 10 * cycle time.
Therefore, a cycle time of 2 ms is equal to 20000 µs.

If a smaller value is set for P-CHAN-00065, the value is corrected to the minimum value.
