Product Description:
The 01.S4.D4E-3001 servo controller is manufactured by KEB as part of the S4 Combivert Servo Controllers series. The unit converts fixed-frequency factory power into precisely timed output phases so that closed-loop motion axes can follow torque, speed, and position references in material-handling, printing, and assembly equipment. It occupies a compact frame suited for panel mounting close to the machine.
This model belongs to the 400 V class and can be connected to mains supplies ranging from 305 V AC to 500 V AC. The rectifier and intermediate circuit are designed for a three-phase supply operating at 50 Hz or 60 Hz, eliminating the need for external power conversion hardware. Within that electrical range, the controller’s power section keeps ripple low, and its DC link maintains the bus level needed for full torque during dynamic load changes. A resolver serves as the primary feedback system, while the controller provides incremental encoder simulation so downstream PLCs that require quadrature signals can receive position information. The controller uses Housing Design D, which provides consistent terminal locations and airflow paths within the cabinet.
The controller carries an IP20 protection rating and operates from -10 °C to 45 °C without derating. This operating range supports continuous duty in climate-controlled rooms and enclosed industrial control cabinets. For storage, the controller tolerates temperatures between -25 °C and 70 °C. Motion profiles are calculated around a motor reference speed of 3000 rpm, which is common for servo stages in pick-and-place gantries and indexing tables. The controller can be installed beside other control electronics without requiring additional ducting when the specified spacing and ventilation conditions are maintained. Built-in diagnostics monitor operating conditions and provide warnings before a supported limit is exceeded, helping prevent interruptions during demanding motion cycles.
