Product Description:

The S77202-FBF2-PM is a servo drive produced by Kollmorgen in the S700 Servo Drives series. It conditions three-phase mains power and modulates current to synchronous or asynchronous servomotors, allowing tight velocity, torque, and position control in industrial automation cells that need integrated safety and high-speed feedback processing.

The power stage accepts line voltages from 208...480V and can process up to 50 kVA of apparent power through its standard PCBs. Continuous motor load is supported with 72 Arms of rated current, while the output can surge to 140 Arms for 5 s to cover acceleration peaks. An IGBT bridge that switches at 8 kHz keeps current ripple low, and the internal path shows only a 6 V residual drop. Secondary encoder devices receive 5 VDC at 300 mA, and the Posi/O port carries 5 V differential signals. That interface sustains data rates up to 1.5 MHz, giving precise position capture that matches the dual-channel STO safety input. Cooling is handled by the F2 controlled fan, and a dedicated fan-controller expansion card monitors airflow.

Mechanically, the drive is enclosed in a 190 mm-wide housing that rises to 386 mm and extends 244 mm behind the mounting plane when connectors are excluded. The assembly weighs 13 kg, so standard cabinet rails can support it without reinforcement. Controlled air movement from the F2 fan maintains thermal limits for the 72 Arms continuous load, and component spacing on the standard PCB set matches those airflow patterns. Motion applications benefit from the drive’s Dual channel STO capability for safe torque shut-off, while the high-speed feedback link sustains up to 1.5 MHz without signal degradation. Together, these electrical, mechanical, and safety parameters allow dependable integration in systems that require short peak bursts, quick positional sampling, and verified shutdown paths.
