Product Description:

The 09.F5.A1D-LAWA is an axis drive module produced by KEB as part of the F5 Combivert Axis Drives series. It converts fixed-frequency mains power into variable-frequency, variable-voltage output so that synchronous or induction motors can be coordinated in industrial automation cells such as packaging stations, material-handling gantries, or process lines. The module is intended for applications that require controlled motor speed and torque for axis movement.

This drive accepts a three-phase input of 400 V and, through its standard control board, regulates motor current to a continuous level of 4.1 A. That current corresponds to an output rating of 2.8 kVA, which is the electrical load the unit can sustain during normal duty. The insulated-gate transistors switch at a rated carrier frequency of 8 kHz, balancing acoustic noise with switching losses while the heat-sink cooling method removes generated heat. An IP20 enclosure limits accidental contact and is intended for installation inside a closed cabinet. A braking transistor is integrated, so regenerated energy can be routed to an external resistor no smaller than 120 Ω, and overcurrent protection activates at 8.9 A to protect the power stage. The D-type housing profile affects mounting space and airflow requirements.

The dynamic limits are higher than the continuous ratings. The braking path can conduct up to 7.5 A when decelerating high-inertia loads, and the inverter can energize motors rated as large as 1.5 kW for short periods. During rapid torque changes, the gate drivers may be commanded to a maximum switching frequency of 16 kHz, which improves output resolution for fast-response axes but also increases switching losses. Safe operation relies on the heat sink remaining below 90 °C and on the short-time output limit of 7.4 A during use in multi-axis systems.
