Product Description:

The 23.F5.C0R-940A is an axis inverter manufactured by KEB for the F5 Combivert Axis Drives series. It converts three-phase mains power into variable voltage and frequency output for induction or synchronous motors used in automated conveyors, packaging lines, or material-forming cells. By integrating current-vector algorithms and field-oriented regulation, the drive delivers closed-loop speed and torque so multiple axes can be synchronized, energy use can be improved, and motion can be monitored through the same control platform. It can serve as the power stage for applications that require repeatable acceleration, stable speed regulation, and consistent torque during load changes.

The unit accepts a three-phase supply at 400 V, matching common industrial mains for high-power installations, and it is identified by inverter size code 23 so line cabling and protective devices can be scaled accordingly. Under continuous duty, the drive delivers a rated output of 75 kW while supplying the motor with a steady line current of 150 A. Thermal management and semiconductor design support this performance, while the enclosure rating of IP20 indicates that the housing is touch-safe and must be mounted inside a switch cabinet for dust and moisture protection. For pulse-width modulation, the factory nominal switching frequency is 2 kHz, giving a balance between acoustic noise, current ripple, and transistor losses during typical production cycles.

For temporary overloads, the drive can supply a peak phase current of 270 A, which helps during acceleration of heavy loads. When low-inductance machines need finer current shaping, the switching stage can be set to 8 kHz, trading efficiency for smoother torque. The chassis stands 520 mm tall, projects 355 mm deep, and spans 340 mm, all within housing form factor code R. These dimensions permit stacking F5 modules on DIN rail while leaving space for input conductors, motor leads, and cabinet clearances.
