Product Description:
The M.1302.8630 servo feedback cable is produced by Kollmorgen within the Kollmorgen Servo Cables series. It conveys resolver signals, reference voltages, and winding temperature data between an AKD-family drive and the feedback interface on compatible servo motors. By matching the F1/F2 feedback port found on Kollmorgen drives, the assembly supports accurate position control in industrial automation applications that require tight loop closure.
This cable uses a Hi-Flex construction, allowing it to tolerate continuous motion in cable chains without premature fatigue. Its overall length is 1 m (3.3 ft), providing a short run that reduces capacitive loading while allowing convenient routing inside a control cabinet. Eight conductors are sized at 24 AWG, balancing voltage drop against mechanical flexibility in low-power resolver circuits. The drive end terminates in a D-sub 15-pin HD male plug with an angled hood, allowing the harness to clear adjacent modules when connected to the designated F1/F2 receptacle. The internal conductors carry the COS, SIN, REF, and TEMP lines required for feedback and temperature monitoring. An overall shield limits electromagnetic interference that could otherwise disrupt the low-level analog signals.
On the motor side, the cable has a straight connector that mates directly with the resolver header on AKM/DDR motors. The feedback conductors deliver excitation and sensor-return signals over 9 VDC and +5 VDC supply rails, allowing the connected transducer to operate within its required range. Resolver transformation accuracy is preserved by the dedicated four-pair geometry, while the straight connector helps prevent torsion during installation. The cable supports a resolver feedback scheme, providing analog angle data that the drive converts into digital position information for precise motion control.
