Product Description:
The 00.F4.071-0039 is an AC drive manufactured by KEB for the F4 Combivert Frequency Inverters series. It converts fixed-frequency mains power into a controllable output that lets industrial controllers vary motor speed directly from the drive rather than through mechanical adjustments. In automated machines, this conversion supports closed-loop torque regulation and dynamic braking so conveyors, mixers, and pumps can start, stop, and change speed in precise time with process demands.
The control section provides 7 digital inputs that accept a standard +24 V signal level for start, stop, or preset selection commands. Feedback to higher-level controllers is handled by 3 relay outputs; each contact can switch up to 1 A at a maximum of 30 V DC for status or fault indication. Five analog or frequency signal outputs are present, and their combined sourcing capability is limited to 500 mA, preventing external load from over-driving the internal supply. A 100 V endurance rating to ground isolates the logic section from common-mode noise on field wiring. When power is first applied, the inverter waits ten seconds before energizing its output stage so that field devices have time to reach a stable state.
The frequency management routine lowers the carrier to 8 kHz when cabinet temperature approaches the 50 °C warning point and returns to 16 kHz once the heat sink cools to the 40 °C restore threshold. In addition, the braking transistor remains active for five seconds after a stop command to discharge residual DC bus energy. Output regulation uses a total band of 12 % around the setpoint, while the DC-link monitor issues a fault at 6 % deviation to protect semiconductor devices. The signal section can deliver up to 500 mA for tachometer or meter drives without exceeding its internal power budget.
