Product Description:

The 05.S4.D10-3270 servo controller is produced by KEB within the S4 Combivert Servo Controllers series. This unit functions as a closed-loop drive interface between a PLC and a synchronous or induction motor in industrial automation, providing controlled acceleration, speed regulation, and torque-limiting functions during normal machine operation. By combining gate drive electronics with integrated control logic, the controller executes motion commands for conveyors, packaging axes, and material-handling cells that require repeatable motion profiles. That behavior is useful on machinery that depends on consistent starts, stops, reversals, and speed changes across repeated production cycles.

The housing measures 160 mm deep, 240 mm high, and 90 mm wide, giving it a slender profile for standard DIN-rail or panel layouts. Under full load, the S4 controller releases up to 75 W of heat, so cabinet airflow or heat sinking must be arranged to manage internal temperature rise over extended duty cycles. When powered from a single-phase branch, the rectifier draws 12.8 A, a value used to size upstream wiring and protective devices. Thermal monitoring interacts with current-limit logic, and the minimum 1.5 mm² line cross-section helps keep conductor temperature within allowed limits during continuous operation and repeated load changes.

For installations with three-phase supplies, the controller accepts 7 A of input and supports either single-phase or three-phase feeds. The power section is rated for the 50 / 60 Hz ± 2 Hz mains frequency range at the 230 V voltage class, allowing use on standard distribution networks in facilities with either common mains frequency. During rapid acceleration, the inverter can deliver a peak output of 14.8 A (600 ms) before it returns to the continuous 6.4 A stall limit, which also matches the rated output current. Protection fuses should be sized at 16 A on single-phase lines or 10 A on three-phase circuits. The enclosure carries an IP20 rating, so it must be mounted inside a panel that shields the electronics from conductive dust or dripping liquids.
