Product Description:

The 15.F5.CBE-Y00A is a compact axis drive that KEB builds for the F5 Combivert Axis Drives series. As a drive controller, it modulates power for induction or synchronous motors up to the power limit allowed by its housing and inverter size. In automated machinery, the unit sits between the mains supply and the motor, converting DC-link energy into a pulse-width-modulated output while also providing low-level control signals and protective switching for brakes and relays.

The drive is sized for motors drawing no more than 15 HP, so a single unit can cover moderate conveyors, pumps, or gantry axes. Its differential analog interface accepts command signals within ±10 VDC, letting a PLC transmit velocity or torque references directly. Those references are digitized at 11-bit resolution, establishing 2048 discrete steps for closed-loop regulation. Every new sample is captured after only 2 ms, which aligns the controller’s reaction time with fast machine cycles. The digital input terminals load the source with just 2.1 kΩ, reducing current draw on sensor or controller outputs while still providing reliable state recognition.

Status inputs tolerate control voltages from 13 to 30 VDC, covering common 24-volt bus distributions without additional level shifting. Analog feedback to supervisory controls leaves the unit through two configurable outputs, and each value is formatted with 12-bit depth for fine granularity. Internal gate drivers switch at a carrier frequency of 3.4 kHz, balancing acoustic noise against motor current ripple. When the application needs an isolated hardware signal, the relay contact can switch loads up to 30 VDC at 1 A. Additional features include a dedicated 24-volt, 100 mA supply for encoder power and an integrated brake transistor that dissipates regenerated energy during rapid deceleration.
