Product Description:

The 07.F5.CDB-3B0A is an axis drive module produced by KEB for the F5 Combivert Axis Drives series. It sits between a plant’s 400 V three-phase supply or shared DC bus and a connected servo or induction motor, where it regulates voltage and current for controlled speed and torque operation. The unit is intended for industrial automation systems that need compact power electronics with integrated safety functions and built-in electromagnetic compatibility measures.

During continuous operation, the drive can supply 1.8 kVA of apparent power while drawing a nominal line current of 3.6 A. On the motor side, the inverter delivers a continuous output current of 2.6 A and uses space-vector modulation with IGBTs switching at 16 kHz. This carrier frequency helps reduce torque ripple while the commanded output frequency ranges from zero up to 599 Hz. Input power can be supplied from a three-phase 400 VAC source or from a shared DC bus, and the integrated EMC filter helps reduce conducted noise on either source. The unit also includes a safety relay for STO functions, but it does not include an encoder interface, so it is suited to open-loop or sensorless vector operation. Dynamic braking energy is directed to an external resistor with a minimum resistance of 120 Ω, and the internal chopper limits discharge current to 7.5 A.

A heat sink with a forced-air fan maintains thermal stability, and under worst-case switching the assembly releases 90 W into the cooling air while supporting motors up to 0.75 kW. The selected main fuse must not exceed 16 A gG, and protective shutdown occurs if the aluminum base plate reaches 90 °C. The power section is also protected by an integrated brake-transistor monitor and by automatic derating routines that reduce carrier frequency during sustained high thermal load.
