Product Description:
KEB’s 16.F4.C1G-4A02 belongs to the F4 Combivert Frequency Inverters series and is engineered to modulate the speed and torque of three-phase AC motors in automated machinery. The inverter converts fixed line frequency into a variable output through a DC-link topology, allowing precise motor control for conveyors, pumps, or positioning axes on factory floors. This operating method gives the motor adjustable speed while maintaining stable torque response during changing process demand. Eleven parameter groups organize the functional settings, and a hardware current limit helps protect the power section during faults or stalls.
The control section provides 2 analog inputs that accept process signals such as speed references and torque limits, and 1 analog output can retransmit feedback values to external indicators or PLC analog cards. The unit has 4 digital inputs for start, stop, and preset selection, and it can issue discrete status through 2 relay outputs. An internal PI controller maintains closed-loop regulation when process feedback is wired to an analog input, eliminating the need for an external PID module. The drive topology keeps DC-bus energy buffered so dynamic load changes do not propagate back to the supply, which helps the output remain stable when motor speed changes quickly.
The unit includes a factory-installed braking transistor for applications that require rapid deceleration, shunting excess DC-bus energy into a resistor bank. Power conversion is performed through a DC voltage link that feeds an inverter delivering 3 output phases to the motor terminals. The unit uses the Compact control style and is enclosed in G housing type, which maintains wiring space while fitting standard cabinet rail patterns. It also stores 8 parameter sets so different motor or recipe configurations can be selected without re-entering each value, and it can be used with asynchronous or synchronous three-phase AC motors.
