Servo Drive

Matched with DC brush motors with encoder or brushless EC motors with Hall sensors and encoder to 250 watts.


The MAXPOS 50/5 is a motion controller for highly dynamic applications and receives motion and I/O commands from the higher-level EtherCAT master controlling the process. The extremely fast controllers together with the diverse feedback options provide ideal conditions for operation in high-performance applications, raising the bar for precision and synchronization. The MAX-POS 50/5 supports CoE (CAN application layer over EtherCAT).

MAXPOS is a modular, digital positioning controller. It is suitable for permanent magnet-activated DC motors and brushless, electroni-cally commutated EC motors with incremental or absolute encoders with an operational range of up to 250 W continuous power.A wide range of operating modes allows flexible use in a variety of fields in drive systems, auto-mation, and mechatronics.
