EL7201-0000

EL7201-0000 is a Beckhoff terminal in the EL EtherCAT Terminals series. It has one channel for controlling a single servo axis and provides one servomotor output plus one motor-brake output. Resolver feedback supplies motor position and speed information to the controller. Distributed Clocks support synchronized timing across the EtherCAT system.

The servomotor output delivers 2.8 A RMS continuously and up to 5.7 A RMS for one second to accommodate short peak-load conditions. A 16 kHz PWM clock controls motor voltage switching, while the current controller operates at 32 kHz for rapid current regulation. The speed controller runs at 16 kHz to regulate motor velocity.

The integrated brake output supplies 24 V DC at up to 0.5 A for operating the motor brake. The terminal electronics also use a 24 V DC supply. Its power contacts support a load of up to 10 A for passing supply current through the terminal assembly. The IP20 protection rating provides protection against finger contact and solid objects larger than 12.5 mm, but it does not provide water protection.
