Product Description:

The EL7201-0000 is a single-axis EtherCAT servo drive terminal manufactured by Beckhoff within the EL EtherCAT Terminals series. It mounts on the I/O rail and interfaces directly with a compact servomotor, converting the 24 V DC control supply into phase-modulated power while returning position feedback to the central PLC. Used in packaging, assembly, and small-gantry applications, the terminal reduces cabinet space by merging drive electronics and fieldbus communication in a 12 mm-wide IP20 housing.

The power stage delivers a continuous motor phase current of 2.8 A rms and can reach a peak of 5.7 A (1 s) to cover acceleration demands. A pulse-width-modulated bridge clocks at 16 kHz, while the current loop updates at 32 kHz to keep torque ripple low. For holding or emergency stops, the integrated brake output supplies 0.5 A at 24 V DC. One channel handles both motor phases and brake control, and the terminal exposes one output each for the servomotor and its brake. Speed regulation executes at 16 kHz (unbolded), matching the PWM base for deterministic velocity control.

The power contacts pass up to 10 A, so additional 24 V auxiliary loads can be daisy-chained without external wiring. An IP20 rating confines the module to dry, enclosed panels, but it still supports high-precision timing because distributed clocks are present for nanosecond-level synchronization between axes. Resolver feedback is accepted, allowing absolute position evaluation through the Resolver interface without separate encoders. One channel is available, and the output set includes a single servomotor plus a motor brake line, simplifying node counts on dense machines. The electronics require 24 V DC supply yet remain isolated from the high-current power contacts, minimizing common-mode noise on the control backplane.
