Product Description:
The 07.S4.D30-3470 servo controller is produced by KEB within the S4 Combivert Servo Controllers series. The unit converts three-phase mains power from the 200 V supply class into regulated output for synchronous or asynchronous servomotors used in packaging, material-handling, and general motion axes. By controlling current during acceleration, normal operation, and braking, it serves as the actuator interface between higher-level PLC commands and the motor windings in industrial automation systems.
Powered from a 200 V supply class, the controller draws a nominal input current of 3 A through a three-phase mains connection. Under continuous load, it delivers a rated output current of 2.7 A, which matches the motor stall current and supports sustained torque at standstill. Short load surges are handled by a peak current of 8.5 A, which the drive can sustain for 200 ms to reduce following errors during rapid indexing. The housing has an IP20 protection rating, so the controller is intended for installation inside a control cabinet that prevents unintended contact with electrical components. Motor cable length is limited to 50 m, and the PTC thermistor must have a cold resistance below 400 Ω to provide suitable thermal feedback. The controller is designed for operation within the temperature conditions associated with climatic category 3K3.
Upstream circuit protection is provided by a 10 A time-delay mains fuse, while cable cross sections of at least 1.5 mm² satisfy voltage-drop and thermal requirements. The controller maintains full performance at installation altitudes up to 2000 m, with its cooling design accounting for reduced air density. It tolerates relative humidity of up to 95% without condensation, consistent with the tropical classification of its climatic category. During dynamic motion, an overload ratio of 3.1 allows the motor current loop to exceed the nominal current for 200 ms. This short-term current capacity provides reserve torque for accelerating inertial loads or controlling vertical axes before the output returns to its continuous level.
