Product Description:
The 12.F5.G1D-L001 is an AC drive manufactured by KEB for the F5 Combivert Axis Drives series. It is intended to regulate induction or synchronous motors in automated equipment by converting fixed-frequency mains power into variable-frequency, variable-voltage output. Through open-loop flux-vector control or an optional closed-loop configuration when a feedback sensor is added, the unit modulates torque and speed so production machinery can follow process demands without mechanical throttling.
This inverter is sized for motors up to 5 HP, delivering continuous power within that capacity. It generates carrier-based output over a frequency range of 0 to 400 Hz, while the output phase voltage tracks the supply and can reach 3 × 0 to Uin. Input compatibility spans industrial grids operating at 50/60 ±2 Hz, allowing the drive to operate on either frequency without reconfiguration. A maximum switching frequency of 16 kHz allows smoother current waveforms and reduces acoustic noise. When the output frequency falls below 6 Hz, the drive maintains rated torque through its minimum full-load frequency setting. The factory-mounted braking transistor supports the dissipation of regenerative energy, protecting the DC bus during rapid deceleration.
The control system accepts eight discrete commands through 8 digital inputs, while two analog references are available for speed or torque control. Relay feedback is provided by two changeover contacts. Real-time events are polled every 2 ms, aligning control updates with fast motion sequences. Thermal management supports operation at a heat sink surface temperature of up to 90 °C. Reliable service is supported at ambient temperatures from -10 to 45 °C and relative humidity levels from 5% to 85%. Installation is permitted at elevations up to 2000 m, with derating required above this elevation. The inverter has a size code of 12, and its terminal block is scanned in quick succession to refresh input and output status. The assembly withstands switching stresses while the open-loop algorithm maintains motor flux integrity.
