FAQ Question?Is the KEB COMBIVERT F4 series still supported with software or spare parts by the manufacturer? Question?The F4 series is obsolete and no longer actively supported by KEB. Support is limited, and users are typically advised to migrate to modern series like the F6 or S6 for new projects or critical replacements. Question?Can this 07.F4.S3D-3420 inverter be used for a 1.1kW motor? Question?No, this inverter is rated for a 750W (0.75kW) motor. Using it with a higher-rated motor like 1.1kW would overload the drive, leading to faults, overheating, and potential damage. Always match the inverter’s power rating to the motor’s specifications. Question?What type of braking resistor is required for this drive in dynamic braking applications? Question?The specific braking resistor depends on the application’s duty cycle and braking torque requirements. You would need to consult the original KEB F4 series technical manual for the correct resistance (Ohm) and power (Watt) values compatible with the 07.F4.S3D-3420 model.
