Product Description:
The 05.S4.R11-M200 is a digital servo controller from KEB, included in the S4 Combivert Servo Controllers series. It drives synchronous or induction motors in automated equipment by regulating torque, speed, and position with closed-loop current control. Positioned between a PLC and the motor windings, the unit issues timed voltage patterns that match commanded motion profiles. Panel mounting and integrated I/O allow connection of motor power, feedback, and small actuators without separate interface cards.
Two analog command channels accept velocity or torque setpoints at a resolution of 12-bit signed, while two analog monitor channels generate process values with 8-bit granularity. Current feedback is refreshed every 64 µs, a cycle fast enough to support high-bandwidth flux control. The drive supplies a continuous phase current of 6.4 A and tolerates short-term overloads up to 16 A (500 ms) to start heavy loads. Wiring uses a line cross-section of 1.5 mm², and a relay contact rated 30 V DC 1 A can switch brakes or indicators. The drive samples speed every 128 µs to align electromagnetic torque generation with mechanical response, and all electronics are housed in an enclosure with an IP20 rating for cabinet installations.
A built-in resolver is digitized to 12 bits and feeds an internal position controller that holds the shaft within ±1 increment. For systems that expect quadrature signals, a simulated encoder stream delivers 1024 ppr so legacy motion cards receive standardized feedback. During operation, the controller maintains speed to within ±0.5 rpm, even when phase current approaches the stall limit. These accuracy figures, together with the short speed sampling period, allow tight synchronization between multiple axes and reduce following error in pick-and-place or indexing tables.
