# Optimized bus access (P-AXIS-00276)

P-AXIS-00276 | Optimized bus access
Description | To avoid the jitter of the command value output, normally the command value is output right at the beginning of the next cycle of the position controller. This especially is not necessary, if a subordinate driver ensures the synchronized access on the drive (e.g. at digital drives, SERCOS).

The element 'lr_param.field_bus_allows_optimized_schedule' defines whether the access on the drive can be executed in such an optimised way. In this case, the new command values are made available in the same cycle and the actual values of the axes are read in.

To ensure consistency in time during access to all axes, this adjustment must be activated for all axes to take effect. If this adjustment is not selected for at least one axis, it is deselected automatically for all axes!
