The Industrial Raspberry Pi Forum

Hello,

What is the approximate jitter if I do motion control via a Codesys EtherCAT master? Can you provide a range?

Best regards，
Cade

Hello Cade,
The Codesys Control for Raspberry Pi mentions that Jitter depends on many factors, especially on parallel executed Linux applications, and is ideally about 50μs with maximum values of 400μs.
As a general rule for hard motion control ,the Raspberry Pi based system may not yield desirable results.
