Product Description:

The ENC-AKM-009M-MCS-DCA-28-AA is an encoder feedback cable produced by Kollmorgen within the Kollmorgen Servo Cables series. It links the incremental encoder on an AKM servo motor to the matching servo drive. The cable carries the position, commutation, and status signals required for closed-loop motion control in industrial automation cells.

The cable uses a Hi-Flex jacket so the conductors endure continuous chain motion without fatigue. Its overall length is 9 m, allowing controller cabinets to be mounted a moderate distance from the axis while maintaining signal integrity. A D-Sub 15-pin HD male connector terminates the drive end and is molded at a 45° angle to reduce bend stress where it exits a panel. Inside the jacket, the feedback lines are organized as eight pairs of 28 AWG twisted conductors that minimize crosstalk between the A, B, and index channels. The motor side is a straight plug that mates directly with the encoder housing, and the twisted-pair format works with the commutating encoder to keep phase information aligned with motor rotation. Supply lines carry 9 VDC, +5 VDC, and COM so the sensor electronics remain within their specified voltage range. The S1, S2, and S3 switch leads are routed beside the feedback pairs for home or limit detection.

An auxiliary conductor set consisting of one pair of 16 AWG conductors is reserved for optional brake power or temperature sensors without adding bulk to the main signal core. The feedback scheme uses an incremental encoder, and the dedicated A, A/, B, B/, I, and I/ channels deliver differential pulses that reject electrical noise. To prevent insulation damage during installation, the minimum bend radius is 12 times the outside diameter. Shielding around the signal conductors helps limit interference from nearby motor power cables and switching equipment. The flexible jacket supports frequent movement when the cable is routed through cable tracks.
