Product Description:
The 10.S4.D31-4M00 belongs to the S4 Combivert Servo Controllers series developed by KEB. As a Combivert servo controller, it regulates synchronous or induction motors used in positioning, conveying, and general motion tasks on automated machinery. Within a closed-loop system, it issues torque and speed commands while monitoring feedback, allowing the paired motor, which is equipped with a brake and a feather key, to follow programmed profiles with repeatable accuracy.
The control section samples command signals through an analog input that offers 12 bit resolution, and it reports status through an analog output scaled at 10 bit. A dedicated reference rail of +10 V biases the Ref1 channel, whose 40 kΩ input resistance and 500 Ω load impedance accommodate most PLC interfaces. Power is derived from a 200 V three-phase supply with suppression, so overvoltage transients from the mains are attenuated internally. The speed loop is tuned for motors rated up to 4000 rpm, and temperature feedback is accepted from a PTC sensor that measures 400 Ω when cold. The drive has a climatic category of 3K3, allowing operation in control cabinets with moderate humidity and dust. Motor wiring uses four 1.5 mm² power conductors and two pairs of 0.75 mm² signal conductors, enabling brake power and sensor lines to share the same cable harness.
The controller uses housing design D, with a depth of 160 mm, a height of 240 mm, and a width of 90 mm. A protection class of IP20 limits installation to enclosed panels where finger-safe clearances are maintained. Operation is permitted at elevations up to 2000 m above sea level without performance derating, and the 3K3 category supports ambient conditions typically found in standard switchrooms. The mounting holes accept 5 mm hardware, simplifying installation in retrofit frames. Cable entries and mounting geometry maintain clearances around the heat sinks to support airflow while the controller supervises motors fitted with brake assemblies and feather-keyed shafts.
