Product Description:
The 03.S4.02E-3011 servo controller is manufactured by KEB as part of the S4 Combivert Servo Controllers series. It links the machine control layer to a three-phase servomotor and converts power from the DC link into a modulated output that commands torque, speed, and position in CNC tables, packaging lines, and handling cells. The feedback plug supports resolver signals and IG-IO, while internal interference suppression helps the controller close velocity and position loops without external interpolation. This arrangement allows the controller to process motor feedback and regulate motion through the connected drive system.
The controller is powered from a single DC bus operating at 200 V, and it supplies a rated motor phase current of 2.4 A under continuous duty. During transient load events, the output channel can deliver 8.5 A for up to 1200 ms. An overload ratio of 1.3 limits sustained loading and helps prevent thermal shutdowns during demanding motion cycles. The rated speed of 3000 rpm matches standard low-inertia servomotors, while a stall current of 6.4 A sets the maximum current available for producing static holding torque without shaft rotation. Self-ventilated cooling requires no external fan and helps keep internal components within their permitted temperature range during cyclic operation.
Steady-state heat dissipation is 65 W, so the cabinet must provide sufficient airflow or heat sinking for the generated thermal load. The unit has an IP20 protection rating, which provides protection against contact with hazardous internal parts but does not seal the housing against liquids. It can operate at installation heights up to 2000 m, where the reduced air density still permits self-ventilated cooling. Operation is permitted at relative humidity levels up to 95% without condensation. The size D housing must be mounted vertically, and the connected cables must use a 1.5 mm² conductor cross section. The motor cable can have a maximum length of 50 m, which must be observed when routing the connection between the controller and motor.
