50W EtherCAT Servo Motor in a 40mm Frame with 17bit Absolute Encoder (iESVH40-30-05-24-17BC-RC/EC)

In dense laboratory and optical equipment, the motion axis must fit the instrument, not the other way around. The iESVH40-30-05-24-17BC-RC/EC is a 50W EtherCAT Servo Motor in a 40 mm frame that carries a 17-bit absolute encoder and the full fieldbus suite on a single compact unit.

50 W Fieldbus Servo in a 40 mm Frame

This is the smallest power rating in the fieldbus integrated series: 50 W at 3.4 A, supplied from 24 VDC, in a 40 mm frame. It still carries a 17-bit absolute encoder and the full RS485/CANopen/EtherCAT communication suite on RJ45, so it can join a motion bus as a small, precise node.

What the Integrated Design Buys at This Size

At 40 mm, external drive hardware would dominate the machine layout. Integrating the amplifier keeps the axis footprint small and removes the separate encoder, power, and signal cables, which is significant in dense laboratory and optical equipment. The unit installs as a single component with a DC feed and a network drop.

Protection and Control Behavior

The unit protects against overcurrent, overvoltage, undervoltage, and excessive position deviation. Absolute position from the 17-bit encoder is available after power-up, supporting repeatable positioning in pump and inspection systems without a referencing cycle.

Applications

Robotics, semiconductor equipment, medical equipment, laboratory equipment, optical equipment, inspection equipment, and pump systems. The 24 VDC input and small frame make it a good match for benchtop instruments and compact handling modules.
