Product Description:
The 09.F5.B1B-LA0A axis drive is manufactured by KEB and belongs to the F5 Combivert Axis Drives series. Designed for BASIC open-loop flux vector control, the unit modulates input power to govern the speed and torque of connected motors in automated machinery such as conveyors or packaging stations. Its current regulation operates without encoder feedback, while adjustable inverter settings support controlled motor performance across a range of industrial motion applications.
On the supply side, the drive accepts a DC bus between 420 to 746 V DC, derived from a front-end rectifier connected to a mains network in the 400 V class. When operated from an AC source, the input window spans 305 to 528 V AC, allowing the unit to tolerate normal utility fluctuations. The nominal line frequency is 50/60 ±2 Hz. The connection requires three input phases, providing the balanced supply needed by the inverter power stage. Under these conditions, the inverter delivers a rated motor output of 1.5 kW and a continuous motor current of 4.1 A at the terminals. Its apparent output reaches 2.8 kVA, providing the electrical capacity needed to support the stated motor load.
The housing uses form factor B to dissipate heat generated by conduction and switching losses. At continuous load, power loss is 75 W with a DC supply, while total inverter power loss is 80 W. A built-in braking transistor directs regenerated energy to an external braking resistor with a resistance of at least 120 Ω, and the transistor can conduct up to 7.5 A of braking current to stabilize the bus voltage. Short-term output current reaches 7.4 A, while the overcurrent trip activates at 8.9 A to protect the power semiconductors. The default carrier frequency is 8 kHz, but the drive can be configured for a maximum switching frequency of 16 kHz when reduced motor noise or smoother torque is required.
