Product Description:

The 09.F5.B1B-3A00 is a three-phase axis drive from KEB that belongs to the F5 Combivert Axis Drives series. Designed as a variable-speed controller for asynchronous or synchronous motors, the unit modulates the applied AC waveform to manage speed, torque, and position loops in production machinery, packaging lines, and material-handling systems. By integrating gating, current monitoring, and a factory-mounted braking transistor, the drive supplies regulated power to a connected motor while dissipating regenerated energy during deceleration.

For the mains supply, the drive operates from 400 VAC and draws a continuous input current of 6 A. Its inverter bridge provides a continuous phase output of 4.1 A, supporting loads up to 2.8 kVA at the motor terminals. Internal IGBTs switch at a rated carrier frequency of 8 kHz, balancing acoustic performance with switching losses. These electrical limits correspond to a nominal power loss of 80 W that must be removed through the aluminum heat sink. An overcurrent trip is set at 8.9 A, and the short-term current reserve reaches 7.4 A, allowing transient acceleration without nuisance faults. The main supply fuse should be limited to 16 A to coordinate with the protective logic.

The carrier frequency can be increased to 16 kHz when low-noise operation is required, provided that the heat sink temperature stays below 90 °C. Within this thermal range, the drive can energize motors rated at up to 1.5 kW, with stable torque available down to a minimum full-load frequency of 6 Hz. Mechanical ingress protection is classified as IP20, so the unit must be installed inside a control cabinet. No encoder feedback card is installed, but position control can be added later through an optional plug-in module. During rapid stops, the integrated braking transistor directs surplus DC bus energy to an external resistor, preventing DC overvoltage events and maintaining bus stability.
