Product Description:

The S74802-SEF2-F2 is a servo drive manufactured by Kollmorgen within the S700 Servo Drives series. The unit conditions incoming three-phase power and regulates motor current so that position, velocity, and torque commands from a motion controller are reproduced accurately at the machine axis. By combining power conversion, closed-loop control, and embedded safety into one chassis, it simplifies integration of high-performance servomotors in automated packaging lines, electronic assembly cells, and other industrial equipment that demand repeatable dynamic response.

Electrically, the drive operates on a mains range of 208 to 480 V three-phase AC and draws up to 35 kVA under rated load. Its continuous output capability of 48 Arms supports medium-power rotary axes, while a peak provision of 96 Arms accommodates acceleration bursts and transient overloads. The power stage is clocked at a switching frequency of 8 kHz, balancing current ripple and semiconductor losses. Internal gating allows thirty start-stop cycles per hour, matching the stated switch-on and switch-off limit. The architecture uses standard PCBs for general-purpose applications, and thermal management can be supported by an optional fan controller card fitted in the designated expansion slot.

For cabinet layout, the body measures 386 mm in height, 190 mm in width, and 244 mm in depth without connectors, yet it weighs only 13 kg. Control wiring is powered from an auxiliary supply of 24 VDC, leaving the main bus isolated when the system is idle. Functional safety is provided by a dual-channel STO circuit, and real-time drive coordination is handled through a SERCOS II interface installed in slot 1. An IP20 enclosure rating requires installation inside a protective cabinet, and fan-assisted cooling removes heat from the power section.
