EtherCAT Architecture
Engineering architecture for controller, servo, remote I/O, cycle time, axis count and topology.
Engineering selection, not blind model matching.
This page separates published product information from project-specific engineering advice. Final ordering code depends on the full suffix, controller, protocol, mounting, quantity and destination.
Complete selection classification
Use this table for pre-selection. Confirm the latest official FLEXEM datasheet before ordering.
| Controller layer | Motion PLC / EtherCAT master |
|---|---|
| Drive layer | EtherCAT servo axes |
| I/O layer | Remote I/O and distributed sensors |
| Key design inputs | Cycle time · synchronized axes · topology · cable length · diagnostics |
| Commissioning | Device addressing · ESI files · motion configuration · fault recovery |
| Boundary | Safety functions require separate formal machine-safety design |
Important: published values may vary by exact model suffix. Product compatibility, certificates, mounting dimensions and accessories require final confirmation.

Selection questions
Is EtherCAT always better than pulse control?
No. Select it when synchronization, diagnostics, wiring and multi-axis architecture justify the added system complexity.
What determines cycle time?
Controller performance, number of nodes, distributed clocks, process logic and network configuration.
Do I need to verify each servo?
Yes. Confirm EtherCAT profile, ESI file, control mode, motor and commissioning software.
Need price, lead time or compatibility confirmation?
Send the exact model / current installed model, quantity, controller/protocol and destination. We verify first, then quote.
