KDF Variable Frequency Drives

KDF Variable Frequency Drives are Bosch Rexroth cabinet-mounted drive modules used in legacy industrial systems for controlled AC motor and spindle operation. The series operates within a DC-bus-based drive architecture, where the KDF module works with related Rexroth power and control components rather than functioning as a standalone VFD. Different current classes are available so the drive can be matched to the required motor load and machine duty. KDF units were used in cabinet-based automation systems that needed regulated speed and torque control, with configurations that include blower cooling and separate control-voltage inputs. Because these drives are tied closely to the original system architecture, replacement or service decisions depend on cabinet layout, electrical interfaces, cooling arrangement, and compatibility with the existing drive package. Overall, the KDF series is most relevant for maintaining older Rexroth installations where the original drive-system configuration must be preserved.
