Product Description:

The 17.F4.C1G-M420 is a compact AC drive produced by KEB for the F4 Combivert Frequency Inverters series. It converts fixed-frequency three-phase mains power into a variable-frequency, variable-voltage output so an induction motor’s speed and torque can be matched to process demand in automated machinery and material-handling equipment. This allows smooth motor control in conveyors, fans, pumps, and similar variable-speed systems where operating conditions can change during use. A compact control housing also simplifies panel layout in space-limited enclosures.

The inverter provides 2 analog inputs and 4 digital inputs, allowing a controller to send proportional setpoints or on/off commands directly to the drive. Internally, it has a frequency resolution of 0.0125 Hz, which lets a PLC establish precise motor speeds without noticeable hunting during low-speed adjustment or fine trimming. The unit can reach a maximum output frequency of 409.5875 Hz, enabling high-speed applications such as centrifugal pumps and spindle drives where the connected motor is suitable for elevated running speeds. It also provides three output phases for motor connections, and an integrated braking transistor dissipates regenerated energy into an external resistor during rapid deceleration to help prevent DC-bus overvoltage.

Field wiring flexibility includes one analog output for feedback of process variables and one digital output that can flag status conditions such as drive ready. Two form-C contacts supply two relay outputs for higher-power signaling to interlocks or contactors, which is useful when the drive must exchange simple status signals with surrounding control hardware. Configuration is organized into 11 parameter groups, and eight selectable parameter sets allow quick switching between different motor recipes without reprogramming. This structure keeps operating settings grouped in a clear way when one machine must support more than one production mode.
