Product Description:

The 09.F5.CBD-YA53 is a frequency inverter manufactured by KEB for the F5 Combivert Axis Drives series. Installed between the line supply and a three-phase motor, the unit converts fixed-frequency input power into a variable-frequency output to regulate speed and torque in conveyors, pumps, and coordinated axis groups on automated lines. Its design integrates the control electronics, power section, and cooling hardware inside a single drive frame for panel installation.

The power stage is fed through 3 input phases, which allows symmetrical loading of industrial distribution networks at a line frequency of 50/60 Hz. Circuit designation A1 identifies the rectifier layout and EMC filtering used at the input stage. After conversion, the inverter supports a minimum full-load operating frequency of 6 Hz, so low-speed ventilation or positioning tasks can be carried out without external gear reduction. Rated apparent power is 2.8 kVA, and when matched with a standard-efficiency motor, this supports mechanical output up to 1.5 kW. Closed-loop current regulation within this range helps maintain stable torque across the speed band while protecting the power modules from overcurrent.

Deceleration energy is managed by an internal braking transistor, which diverts excess DC-bus energy during rapid speed changes. Cooling air is moved by an integrated fan and expelled through a rear channel in the drive's D housing, helping keep the heat sink below 90 °C during operation. The unit uses the Compact control concept, so parameterization, diagnostics, and fieldbus options are housed on the primary board instead of external modules. A monitored safety relay is included, and STO commands can disable gate firing without removing line power. This arrangement allows the control system to stop torque production while communication and diagnostic access remain available.
