Product Description:
The 07.F4.S1D-4A01 is an AC frequency inverter manufactured by KEB as part of the F4 Combivert Frequency Inverters series. The unit rectifies mains supply and generates a variable-frequency output, enabling precise speed control for small asynchronous motors used in conveyors, pumps, and packaging stations. By combining power electronics, field-oriented control, and basic machine interface signals in a compact format, the inverter automates low-power axes without additional external drives.
Its analog command channel presents an input resistance of 56 kΩ, so a standard 0–10 V speed reference draws minimal load from upstream PLC cards. Logic terminals are energized by a 15 V digital I/O supply, while a separate 10 V rail is available for an external potentiometer that may dissipate 0.5 W. An internal brake transistor shunts regenerated energy into an external resistor during rapid deceleration. To coordinate with switchgear, the drive is protected by a maximum mains fuse of 10 A. Under rated operation, it delivers 1.8 kVA of apparent power to the motor and loses only 45 W as heat, which simplifies enclosure thermal calculations. If the motor current rises to 5.7 A, the overcurrent trip halts the inverter to prevent device stress.
During operation, the aluminum heat sink may reach up to 85 °C; a built-in PTC sensor and a normally closed thermocontact supervise this surface and issue a warning or shutdown before thermal limits are exceeded. Continuous output is rated at 2.6 A, but the inverter can supply a short-time surge of 4.6 A for acceleration or peak load events, provided the input side draws its nominal 2.8 A. On the motor shaft, this current corresponds to a mechanical output of 0.75 kW. These current and power limits support cable sizing, overload relay selection, and duty-cycle planning for connected equipment.
