Product Description:
The 00.F4.509-0001 is a preassembled feedback lead manufactured by KEB for use with drives in the F4 Combivert Frequency Inverters series. Classified as an accessory rather than a power cable, it provides a deterministic data path between an external motor encoder and an internal repeater that extends the synchronous bus. In industrial automation lines, this link allows the inverter to receive real-time shaft position signals so multiple axes operating in master-slave control can maintain coordinated speed and phase. Because the encoder information reaches the repeater with low latency, linked motion channels can follow the same timing reference more consistently.
The assembly has a fixed length of 1 m, which is short enough for drive cabinet layouts while still reaching from the encoder terminal block to a nearby repeater. It is identified as a master cable, so it carries the primary timing stream rather than subordinate responses. One end uses a shielded 9-pole male D-Sub connector that mates with the encoder socket, and the opposite end is pinned identically for the inverter interface, which eliminates the need for gender adapters. The conductors are twisted in pairs, and the wiring follows the master-slave bus used by the drives. Using identical pinning on both ends keeps the signal path straightforward inside compact control enclosures. The factory-terminated harness also helps reduce wiring errors during installation.
The drive transmits through the Encoder Output, and the cable connects to the repeater's MS Repeater MASTER IN receptacle so differential signals can pass downstream. The cable is without a supply connection, so no auxiliary power cores are present and all conductors are dedicated to data transmission. Its impedance-matched pairs and continuous shielding help limit reflections and electrical noise, which preserves edge integrity for deterministic control and supports cyclic position sampling across follower axes. Since the cable does not carry supply conductors, available space inside the jacket is reserved for feedback wiring and shielding elements. This arrangement helps maintain stable synchronization when several connected axes must track the same timing reference.
