Product Description:
The 09.F4.C1D-4999 is a frequency inverter manufactured by KEB as part of the F4 Combivert Frequency Inverters series. The device belongs to the COMBIVERT F4 product type and converts a fixed mains supply into a variable electrical output. By adjusting voltage and frequency, the inverter allows motor speed and torque to follow changing process demands. It supports induction and synchronous motors used in conveyors, pumps, and positioning axes that require accurate speed regulation. Its compact design also supports installation in control cabinets where mounting space is limited.
The inverter uses the Compact control mode, which provides streamlined parameter sets while retaining vector-control routines for responsive torque regulation. Its housing follows the Compact D-size format, so its mounting-hole arrangement and airflow paths correspond to other D-size modules in the platform. The drive supports motors with outputs up to 1.5 kW, making it suitable for smaller machine axes and auxiliary equipment. At rated line conditions, the power stage provides a nominal output of 2.8 kVA. An integrated braking transistor redirects regenerative energy to an external braking resistor during deceleration. This arrangement permits faster stopping while reducing the likelihood of DC-bus overvoltage trips. The selected resistor must be suitable for the regenerative energy and braking duty of the connected load.
The enclosure has an IP20 protection rating and must be installed inside a closed panel to prevent direct contact with live electrical parts. Permissible ambient air ranges from -10 to 45 °C, with applicable derating required when operating conditions fall outside the normal range. Relative humidity may reach 95 percent as long as condensation is prevented inside the enclosure. Maintaining adequate cabinet ventilation helps control semiconductor temperatures during continuous operation. The installation area should also remain free of moisture accumulation that could corrode control electronics or reduce insulation performance. Proper panel spacing allows cooling air to pass through the housing without obstruction, while a dry interior protects the inverter’s power and control circuits during extended machine operation.
