Product Description:
The 05.S4.D11-327E is a servo controller produced by KEB within the S4 Combivert Servo Controllers series. Designed to modulate power to closed-loop AC servomotors, it handles speed, torque, and positioning tasks inside automated machinery. The unit interfaces between mains supply and motor windings, translating command signals from a PLC into precise current and voltage patterns. By coordinating motor behavior, it supports conveyor sections, pick-and-place axes, and other motion stages that require repeatable dynamic response.
Electrical parameters show how the controller is cabled and supplied. It operates from a nominal line of 230 V AC and accepts either single-phase or three-phase feeds through its 1/3-phase input design. Under continuous load, the inverter delivers a rated output current of 6.4 A to the motor, while the single-phase mains side can draw up to 12.8 A. When powered from three phases, the input current falls to 7 A, improving fuse coordination with the recommended 10 A device. An auxiliary output bus provides +24 V for encoder or brake supply. The stall current matches the rated figure, so the thermal profile remains unchanged during locked-rotor conditions.
Installation criteria focus on wiring, environment, and protective hardware. Power conductors up to 1.5 mm² can be landed at the terminals, and relay contacts inside the unit are rated for 30 V DC at 1 A to switch external interlocks. Overcurrent protection on single-phase supplies relies on a fuse rated at 16 A. The housing carries an IP20 ingress rating for use inside electrical panels, with safe operation between -10 °C and +45 °C and relative humidity not exceeding 95%. The controller sustains full output up to altitudes of 3000 m and continues to function in humid or dusty shop floors when kept behind a control cabinet door.
