Product Description:
The 12.S4.ED0-6K01 is a servo controller produced by KEB for the S4 Combivert Servo Controllers series. It converts fixed-frequency plant power into regulated three-phase output so that servo motors can follow precise speed, torque, and position commands in automated packaging lines, gantry systems, and material-handling stations. By integrating the control electronics and power stage in a compact enclosure, the unit provides a ready-to-install module that regulates attached motors while monitoring current, temperature, and supply quality. Its control functions support coordinated motion where repeatable acceleration, deceleration, and positioning are required during normal machine operation.
The controller connects to a three-phase supply at 400 V and draws 18.2 A during nominal operation; conductors must have a minimum cross-section of 2.5 mm² and may be protected by a 20 A mains fuse. On the motor side, it delivers a continuous output of 16.5 A, matching its stall current, and it can sustain an overload factor of 3.0 for brief torque surges. These excursions raise thermal output to 240 W, so cabinet airflow must remove the generated heat. The housing carries a protection rating of IP20, the climatic class is 3K3, and the overall mass is 3.5 kg, allowing installation on standard DIN rails without additional structural support. This arrangement supports compact panel layouts while keeping wiring and heat management straightforward.
Dynamic events are handled by a peak current of 38 A that can be maintained for 600 ms before the unit returns to the continuous rating. Environmental limits include operation up to 2000 m altitude and tolerance of relative humidity up to 95 % without condensation, which are conditions commonly found in factory electrical rooms. Within these limits, the internal DC bus and power semiconductors can operate within their normal thermal range during continuous-duty automation cycles. This helps the controller maintain stable output during repeated acceleration and deceleration in enclosed control cabinets.
