Product Description:

The 12.F5.M3D-Y080 axis drive is produced by KEB for the F5 Combivert Axis Drives series. It is a field-oriented inverter that supplies regulated power to an induction motor, enabling accurate speed and torque control in automated conveyors, wrapping lines, and similar machinery. By integrating current, voltage, and temperature feedback, the unit maintains consistent operation during demanding industrial duty cycles.

Internal electronics sample analog reference signals with 12-bit resolution and use a 3.4 kHz carrier for fine voltage modulation at low speeds. The drive executes closed-loop field-oriented control, while eight digital inputs and two digital outputs exchange status signals with a PLC. Because an encoder feedback card is absent, the vector algorithm estimates rotor position from motor current. The power stage accepts 400 V at a rated input current of 13 A and delivers an output current of 9.5 A, providing 6.6 kVA of apparent power. The power devices use an 8 kHz baseline switching frequency that may be increased to 16 kHz when reduced audible noise is required. The inverter has size code 12, and its built-in braking transistors and EMI filter reduce the number of separate panel components. Full-load operation is available from 6 Hz, nominal power loss is 160 W, and the short-term overload current is limited to 17 A.

Thermal supervision activates when the heat sink reaches 90 °C, helping prevent damage to the insulated-gate bipolar transistors. During rapid acceleration, the output current can rise briefly until it reaches the 21 A overcurrent threshold, at which point the drive trips. Within these protective limits, the inverter supplies up to 5 HP of mechanical power to the connected motor. Command and diagnostic cycles refresh every 1 ms, keeping the control loops aligned with machine dynamics even at low operating frequencies. Current monitoring also allows the controller to respond quickly to abnormal motor loading before prolonged stress affects the power stage.
