Product Description:

The M.1015.7979 servo motor interconnect is produced by Kollmorgen for the Kollmorgen Servo Cables series. It serves as the composite power and signal link between a drive controller and its matched servomotor, which is required in industrial automation where coordinated torque and position commands must withstand continuous flexing and electrical interference. It routes phase current, encoder data, and protective earth conductors through a single jacket, simplifying machine wiring and reducing the number of separate cable runs needed between the cabinet and motor.

The cable is supplied in fixed lengths of 30 m (100 ft), giving machine builders a predictable reach from control cabinets to moving axes. A nominal outer diameter of 0.38 in permits tight bend radii without exceeding strain limits in compact routing paths. Current conductors use mixed gauges of 28 AWG and 16 AWG, balancing voltage drop with the flexibility needed for repeated movement. The applicable power and feedback conductors are arranged as twisted pairs to minimize crosstalk between circuits. Electromagnetic integrity is further reinforced by an overall copper braid with at least 85% coverage, allowing the drive system to meet common electromagnetic compatibility requirements in motor environments.

A circular adapter with an outside diameter of 1.36 in mates the cable to cabinet bulkheads, and its backshell provides continuous 360° shielding so the braid bonds directly to ground at entry points. The outer jacket is molded from a thermoplastic elastomer, providing resistance to oil and coolant during cable-chain motion, while the connector overmold uses black PVC rated for service temperatures up to 105 °C (221 °F) so thermal excursions inside press brakes or packaging ovens do not degrade the strain relief. Individual cores are insulated with polyvinyl chloride, and the customer-side pigtail supports soldered, screw-terminal, or crimped attachment when a standard mating plug is unavailable.
