Internal Product Review
The 10.S4.D30-347M is a KEB S4 Combivert servo controller designed for three-phase motion systems, with 305...500 VAC mains voltage and 4.4 kVA apparent power. A rated output current of 6.4 A and peak current of 22 A for 200 ms give this unit confident transient response during demanding servo moves. IP20 protection and an operating range of -10 to +45 °C make this controller a strong fit for enclosed industrial installations.

Product Description:
The 10.S4.D30-347M is a servo controller produced by KEB in the S4 Combivert Servo Controllers series. This unit interfaces between a three-phase AC supply and a synchronous or induction motor, shaping current and voltage so the drive can execute precise speed or torque commands issued by a PLC. In automated production lines, it forms the core of closed-loop positioning axes, coordinating motion sequences while protecting the connected motor from overload. It accepts field-level analog and digital commands and returns status signals to supervisory controls.
Command resolution is 12-bit, so each of the controller’s two analog channels distinguishes 4,096 discrete levels across an input span of ±10 V differential. This fine granularity allows smooth velocity ramps instead of stepwise changes. The device is designed for an AC input range of 305 to 500 VAC, draws 7 A nominally, and is protected upstream by a 10 A fuse. Under these conditions, it can deliver an apparent power of 4.4 kVA to the motor terminals. Continuous motor current is limited to 6.4 A, while transient load spikes are handled with a peak capability of 22 A for 200 ms to reduce nuisance trips during acceleration. Line conductors up to 1.5 mm² can be terminated at the spring clamps, and the three-phase 50/60 Hz input keeps the internal DC link charged for regenerative operation.
The logic terminals accept control signals such as enable, direction, and error reset at 13–30 VDC, permitting direct wiring to standard PNP sensor blocks without extra level conversion. Feedback to the cell controller is supplied through an isolated relay that switches up to 30 VDC at 1 A, which is useful for fault signaling. The housing has an IP20 rating, which supports cabinet installation and guards against accidental finger contact. Thermal design supports continuous service from -10 to +45 °C, so the unit can operate beside other drives in an enclosed panel without forced cooling if convection paths are maintained.
