Product Description:

The 10.5F.C1D-YF12 axis drive is produced by KEB and belongs to the F5 Combivert Axis Drives series. It is intended for closed-loop control of induction or servo motors on automated machinery. By modulating a 400 V intermediate circuit, the unit delivers a regulated three-phase waveform so motion sequences can be synchronized with PLC commands. An integrated brake transistor dissipates regenerated energy, allowing rapid stops without external braking hardware. Rated for a maximum motor size of 3 HP, the device covers small to medium mechanical loads found on packaging lines, indexing stations, and light material-handling axes.

The drive employs water cooling, which moves heat away from the internal power stack and keeps semiconductor junctions below critical limits under continuous cycling. On the line side, it draws 8 A at a nominal input of 400 V through either AC or DC feeds, matching common factory supply levels in 400 V systems. Inverter size code 10 indicates the mechanical frame and connection geometry for cabinet integration. A braking path can discharge up to 10 A, provided that the external resistor is no less than 82 Ω. When commanded, the power section delivers carrier pulses at a rated switching frequency of 16 kHz, creating a smooth sinusoidal output that supports motor frequencies up to 400 Hz without noticeable acoustic noise or torque ripple.

The output stage supplies 5.8 A per phase across all three output legs and can furnish a continuous apparent power of 4.0 kVA. Short transients such as acceleration spikes are supported up to a current that is 240% of the 5.8 A rating, while separate short-time protection allows 200% for brief intervals before foldback occurs. Safe operation depends on maintaining the heat sink temperature below 90 °C, so the liquid circuit ties into a common cooling manifold and the braking transistor uses a suitable external resistor to keep the DC-link voltage within limits.
