Product Description:
The 12.F5.B1B-3500 is an AC frequency inverter from KEB in the F5 Combivert Axis Drives series. It converts fixed line power into adjustable voltage and frequency so connected motors can run at commanded speeds. That control helps automated equipment maintain torque during changes in load, speed, or process demand.
Power enters through a 3-phase 400 V AC/DC supply connection, and the IGBT output stage delivers a continuous current of 9.5 A. That rating suits motors up to 5 HP in applications that need reliable speed control without unnecessary oversizing. A switching frequency of 4 kHz balances audible motor noise and inverter losses, while the control section uses 24 V DC for electronics and field devices.
During acceleration, current demand can rise to 21 A, but trip protection intervenes at 180 % to help prevent damage under conditions. The power section also tolerates 150 % current for short overload periods, which supports brief torque peaks during starts or rapid speed changes. Control scanning updates every 2 ms, coordinating the integrated digital and analog I/O, relay status outputs, and the built-in braking transistor for regenerative events.
The encoder feedback slot is empty, so the drive is configured for sensorless operation rather than motor feedback devices. Standard cooling removes heat without an external blower, which helps simplify panel layout. Wake Industrial stocks this drive, offers same-day shipping on qualifying orders, keeps quotes valid for 30 days, and provides the chat tool available on the website for general questions about fault codes or type codes.
