Product Description:

The 14.F5.C3D-YG1A inverter is manufactured by KEB as part of the F5 Combivert Axis Drives series. Classified under inverter size code 14, the unit includes an integrated braking transistor and an EMI filter, which reduce the need for separate external hardware, handle regenerated energy during deceleration, and help limit conducted interference on the supply lines. It is intended for automated machinery where closed-loop regulation of speed and torque supports stable axis motion, repeatable speed changes, and consistent response in positioning or conveying tasks.

The drive’s mains side accepts a three-phase supply at 400 V with a continuous input of 23 A, protected by a 25 A main fuse for upstream circuit protection. Internally, that energy is converted into an output capability of 11 kVA and 16.5 A rms at the motor terminals, enabling the specified 10 HP rating at 50/60 Hz and during 230 V Unit B operation. A 10 VDC reference source is available for external potentiometers, and the 24 V encoder and logic rail can supply 100 mA for feedback devices or sensors that need low-power auxiliary voltage. Thermal monitoring limits operation to a heat-sink temperature of 90 °C to help prevent derating and protect the power section during continuous use.

For transient loads, the inverter can deliver 29.7 A for short periods before the electronic current limit engages, while a hardware overcurrent trip activates at 35.6 A to protect the IGBTs from excessive stress. Control resolution is matched to modern PLC requirements: the analog outputs are pulse-width modulated at 3.4 kHz with 12-bit depth, and the analog inputs provide 11-bit resolution with a 2 ms scan time for responsive reference processing. Digital inputs present a 2.1 kΩ impedance, allowing direct connection to sourcing or sinking field devices without excessive loading. That combination allows the drive to process reference signals and field states without heavily loading connected devices during normal operation.
