Product Description:

The 10.S4.DB0-348A servo controller is manufactured by KEB and belongs to the S4 Combivert Servo Controllers series. It acts as the motion-control core in industrial automation cells, converting velocity or position commands from a host PLC into controlled three-phase power for synchronous or asynchronous motors. In this role, the device ensures repeatable positioning, manages dynamic load shifts, and coordinates multi-axis moves in packaging machinery, material-handling systems, and assembly stations.

The controller receives differential analog references through inputs that present an impedance of 40 kΩ, and these inputs are digitized with a resolution of 12-bit for fine setpoint granularity. Commanded values are returned to external hardware on a 100 Ω low-impedance channel with an output granularity of 10-bit. Digital status lines can source up to 20 mA, allowing direct driving of opto-isolated indicators or high-speed counters. Internally, the position counter works with a native granularity of 65,536 inc/rev, aligning with high-resolution encoders for smooth servo loops. Complementary resources include a voltage-mode reference port that can supply 60 mA, eight non-volatile position registers for index moves, and an overload capability that lets current peak temporarily without drive shutdown.

The current-to-torque converter tolerates transients at an overload ratio of 3.4, supporting rapid accelerations without derating. An enclosure rated at IP20 protects the electronics when the unit is installed inside a cabinet, and 5 mm mounting holes simplify panel integration. Relay contacts switch loads up to 1 A at 30 V DC for brake release or ready signals, while the ±10 V reference channel provides a calibrated drive signal centered on +10 V. A separate 4 mA reference current source is also available for low-level sensor excitation.
