12.12System sampling times

12.12.1Description

The software functions installed in the system are executed cyclically at different sampling times (p0115, p0799, p4099).

The sampling times of the functions are automatically pre-assigned when configuring the drive unit.

The settings are based on the selected mode (vector/servo), the number of connected components, and the functions activated.

The sampling times can be adjusted using parameter p0112 (sampling times, pre-setting p0115), p0113 (pulse frequency, minimum selection) or directly using p0115.
