Product Description:
The 07.B6.A3A-9A00 frequency inverter is built by KEB within the B6 Combivert Frequency Inverters series. Designed for integration in industrial automation panels, the unit converts fixed mains power into a variable voltage and frequency output so three-phase motors can be matched to application speed and torque demands. By adjusting motor parameters electronically, it eliminates mechanical throttling devices and improves process efficiency in conveyors, pumps, and small machining equipment.
The inverter accepts a supply of 3-phase 400 V AC, routing it through a dedicated heat sink so semiconductor junctions stay within thermal limits during constant operation. Internally, the control section uses a standard PNP interface, enabling direct start-stop and speed commands from typical PLC digital outputs. The default carrier is set at 8 kHz, balancing audible noise against switching loss. At the output stage, the device provides a continuously adjustable frequency range of 0–400 Hz and can deliver up to 4 A of rated current, which corresponds to 1.6 kVA of apparent power for the connected motor. Output voltage is synthesized on three phases and can vary from zero up to the rated mains potential, allowing full motor control. Size code 07 and housing type A set the overall footprint, so the unit fits 45 mm-wide DIN rail sections without extra brackets.
For transient demands, the drive can exceed nominal output. The hardware permits 216% instantaneous overcurrent and supports a short-time surge of 180%, giving additional torque during acceleration or deceleration. The integrated braking transistor GTR7 diverts regenerated energy, while the internal filter keeps conducted emission low and limits leakage to 6 mA at nominal operation. The inverter can start and stop motors up to 0.75 kW without tripping upstream protection.
