Product Description:
The 07.S4.D31-3470 is a servo controller manufactured by KEB for the S4 Combivert Servo Controllers series. Designed for cabinet-mounted automation cells, the device converts line power into regulated current sequences that drive compatible synchronous or asynchronous motors. The connected motor can be equipped with a brake and a feather key for load retention and positive torque transmission. The controller maintains commanded velocity and position profiles in conveyors, handling gantries, and other motion axes where compact control hardware is needed.
The power stage is intended for 200 V three-phase networks and includes suppression chokes. This input arrangement eliminates the need for an external step-down transformer when the controller is connected to a compatible supply. The accepted line frequency is 50/60 Hz, permitting installation on common industrial power systems. During continuous operation, the inverter supplies 2.7 A, while short-term acceleration demands are supported by a peak current of 8.5 A for 200 ms. Electronic monitoring permits an overload factor of 3.1, providing headroom for rapid indexing moves without exceeding thermal limits. Input conductors with cross-sectional areas up to 1.5 mm² accommodate the power connection, while a 10 A mains fuse protects the upstream wiring. A 3 A control input capacity supports the controller’s auxiliary electronics.
The closed-loop regulator uses rotor feedback to maintain synchronism as the motor reaches 3000 rpm. The controller operates within an ambient temperature range of -10 to +45 °C, allowing use in standard shop-floor enclosures without dedicated climate control. The housing has an IP20 rating, which protects against accidental contact with internal components but requires installation inside a sealed cabinet in dusty or wet areas. A depth of 160 mm, combined with a height of 240 mm and a width of 90 mm, fits the D-style enclosure profile and allows predictable allocation of panel space. The compact housing supports cabinet installation where nearby drives, power supplies, and control modules must share limited mounting space.
