Product Description:

The RES-AKM-003M-MCS-DCA-28-NA feedback cable belongs to the Kollmorgen Servo Cables series and is produced by Kollmorgen. It functions as a dedicated resolver harness for AKM servomotors, linking each motor’s feedback connector to the corresponding F-port on a compatible Kollmorgen drive. By transmitting resolver reference, sine, and cosine signals, the cable allows the drive to calculate the rotor position required for closed-loop velocity and torque control in automated machinery.

The assembly has a total length of 3 m (9.8 ft), making it suitable for the mounting distances commonly found between compact control cabinets and nearby axes. It has static, non-flex construction, so the jacket and conductors are intended for fixed routing rather than cable carriers or other continuously moving applications. Inside the sheath, the conductors are arranged as four twisted pairs, which reduce crosstalk between complementary resolver channels and help maintain signal integrity across the full cable length. The drive end uses a 15-pin high-density male D-Sub connector with a 45° angle, reducing the required cabinet depth while matching the feedback ports on compatible Kollmorgen S200 and AKD drives.

At the electronics rack, the cable connects to the drive feedback header marked F1/F2, allowing resolver excitation and return paths to align with their designated terminals without additional pin mapping. The opposite end has a straight molded receptacle that threads directly onto the motor’s resolver bulkhead and helps maintain a secure connection. Within the conductor core, a shielded pair carries the reference carrier, while the remaining signal pairs transmit the differential sine and cosine outputs generated by the motor’s resolver. The available channel set consists of COS¹, SIN¹, REF¹, and TEMP¹, with the temperature channel carrying thermal data that allows the drive to monitor the motor winding temperature and adjust current limits when necessary.
