Product Description:
The 01.S4.D2E-3002 is a Combivert servo controller manufactured by KEB as part of the S4 Combivert Servo Controllers series. The unit functions as a closed-loop drive that handles current, speed, and position regulation for brushless and induction machines used in automated lines. It interfaces with machine control systems through analog references and resolver feedback, delivering the real-time torque commands needed to maintain precise motion profiles in industrial equipment.
It operates from a DC link derived from a three-phase 200 V supply and is rated for a continuous apparent power of 0.46 kVA, matching low-power axes such as feeders or indexing tables. The analog command channel is sampled every 128 µs with 12-bit resolution, so voltage references between ±10 V are digitized with adequate granularity for fine velocity control. Inside the controller, a 16-bit DSP updates the current loops every 64 µs, while a separate 16-bit host processor manages parameter handling and fieldbus traffic. Closed-loop speed regulation holds the shaft within ±0.5 rpm of the target across the rated speed of 3000 rpm. Analog outputs are updated every 2 ms at 8-bit depth and can retransmit measured variables to supervisory systems.
In the feedback chain, the unit synthesizes a simulated encoder stream of 1024 ppr for controllers that expect incremental quadrature signals, while its resolver interface digitizes rotor position with 12-bit accuracy to support electronic commutation. Synchronous operation between multiple axes is maintained within ±0.15° of phase, allowing coordinated motion in gantries and printing lines. The housing follows design D and meets the IP20 protection class, so it is intended for installation inside a ventilated control cabinet. For discrete status control, the built-in relay can switch loads up to 30 V DC, 1 A, isolating the drive from external logic. Unit size 01 keeps the dimensions compact, and interference-suppression components included in the subassembly minimize conducted emissions on the power bus.
