Product Description:

The 13.F5.CBD-YA50 is an AC inverter drive produced by KEB within the F5 Combivert Axis Drives series. In automation systems, it modulates the voltage, frequency, and torque delivered to connected motors so that conveyors, pumps, or positioners run at the speed demanded by the controller. The unit forms the power stage between a plant’s three-phase mains and the motor winding, providing a compact axis solution without external starters or contactors. It can therefore adapt motor output to changing load conditions without relying on mechanical switching methods.

The drive accepts an input supply of 400 V AC or AC/DC, allowing direct connection to standard European mains or rectified bus links. Its power section is rated for 7.5 HP, giving continuous capability for medium-frame motors used on packaging, textile, or small machining axes. Inside, insulated-gate transistors switch at 8 kHz, a carrier frequency that balances acoustic noise with heat dissipation. This switching behavior helps the drive balance audible motor noise with thermal load in typical cabinet installations. If a load surge occurs, the protection logic trips only when current reaches 216% of the programmed limit, permitting brief torque peaks without nuisance shutdown. Physical dimensions follow KEB inverter 13 size code, which keeps mounting holes and cable clearances consistent with other F5 modules.

During acceleration or braking, the unit can supply up to 180% rated current for a short time, supporting high-inertia starts without oversizing the motor. Heat is extracted through the standard cooling variant, which uses integral fans and surface fins so cabinet airflow remains straightforward. The base configuration includes no encoder feedback card, making this build suitable for open-loop V/Hz or sensorless vector control. When wired to a 230 V supply as Unit B, it still delivers 7.5 HP at 230 V, which helps maintain application flexibility in lower-voltage installations that use the same mechanical footprint.
