Motor feedback systems rotary HIPERFACE DSL®
EFS/EFM50

High-resolution motor feedback system for dynamic servo drives

Your Benefits

Thanks to data transmission exclusively in digital format, no analog components are necessary on the controller side
The absence of a separate encoder cable considerably reduces costs. Data transmission is synchronized with the controller cycle.
Minimum cabling thanks to integration of encoder communication into the motor cable
Optimization of the controller circuit via automated synchronization with the controller cycle

Overview
