Pack AK-BX556M

Technical Specifications Cable Type: Flexible, shielded multi-conductor servo cable Conductors: 4 × power (3-phase + PE) + 2 × brake + 9 × feedback signal pairs Conductor Cross-Section: Power 1.5 mm² (AWG 16), signal 0.25 mm² (AWG 24) Standard Length: 6 m (suffix M denotes metric length code; other lengths available) Voltage Rating: 600 V (power), 30 V (signal) Current Capacity: Up to 16 A continuous (ambient 30 °C) Shielding: Overall tinned copper braid coverage ≥ 85 %, individual foil-wrapped signal pairs Connector (Motor End): Kollmorgen proprietary circular connector, bayonet lock Connector (Drive End): Separate power and feedback connectors matching AKD drive Bending Radius: Fixed ≥ 7.5 × cable OD; flexing ≥ 10 × cable OD Operating Temperature: -20 °C to +80 °C (fixed), -5 °C to +70 °C (flexing) Oil Resistance: Compliant with IEC 60332-1 flame retardant Protection Rating: IP65 at motor connector when mated

Functional Features Single-cable solution reduces cabinet wiring and panel penetration Twisted, individually shielded signal pairs minimize encoder noise and crosstalk Low-capacitance dielectric supports long cable runs without signal degradation Color-coded conductors per IEC 60304 for fast field replacement Pre-tested for continuity, insulation resistance, and hi-pot before shipment

Application Scenarios General industrial servo axes in packaging, material handling, and assembly machinery Retrofit and OEM machine builds using Kollmorgen AKM motors with AKD drives Cable tray and drag-chain installations requiring oil-resistant, flexible cabling

Working Principle Power conductors deliver three-phase drive current and DC bus return to the motor stator; brake pair supplies 24 V DC to the holding brake when enabled; feedback pairs transmit differential encoder/resolver signals back to the drive for closed-loop position and velocity control. The overall shield provides a low-impedance EMI return path.

Installation Requirements Route cable away from VFD power cables and high-voltage bus bars by at least 200 mm Use cable glands rated for the cable outer diameter to maintain IP65 at motor entry Do not exceed the minimum bending radius, especially in drag-chain applications Connect PE conductor at both ends; bond shield 360° at drive cabinet entry Leave a service loop of 200 mm to 300 mm at both ends

Usage Precautions Do not splice or extend the cable; use a longer factory assembly instead Inspect connectors for bent pins before mating; never force a misaligned connector Avoid exposing cable to cutting fluids, solvents, or UV radiation beyond rated conditions Torque connector locking ring to manufacturer specification, do not over-tighten Replace immediately if jacket is cut, shield is exposed, or connectors show corrosion
