Product Description:
The 14.F4.F1G-4I30 is a frequency inverter produced by KEB and placed in the F4 Combivert Frequency Inverters series. As an AC drive, it supplies variable voltage and frequency to induction or synchronous motors, making it suitable for conveyors, pumps, and general motion systems that require coordinated speed and torque. The unit is offered as a scalable control platform, allowing analog, digital, and encoder feedback to be integrated without external interface cards. This arrangement supports both straightforward speed control and more complex machine functions in a compact drive package.
Control processing inside the unit uses field-oriented control, and the drive scans all inputs every 2 ms to maintain current vector accuracy. Two differential voltage inputs accept ±10 V reference signals, and the analog channel resolution is 12-bit, allowing fine speed trimming during operation. The inverter offers 6 programmable digital inputs, giving flexible event-driven control for start, stop, direction, and interlock functions. It also includes two analog outputs for meter signals or drive-to-drive communication. Seventeen parameter groups, shown as 17, organize the menu tree so motor, system, and communication settings remain separated and easier to navigate.
Two digital outputs can send status flags to external relays, and a single relay output supports direct switching of contactors or alarms. Input circuits present a 2 kΩ resistance, which suits most 24 V sourcing sensors used in industrial control wiring. A braking transistor is included so surplus DC-bus energy can be routed to an external resistor during rapid deceleration. Encoder feedback is accepted on two channels, while one fixed digital input provides a dedicated enable line. For analog references, the unit supplies +10 V at 4 mA to power potentiometers, and users can store up to 8 parameter sets for different machine recipes or operating modes.
