Kollmorgen CP306260

Product Category: Servo Drive Accessory — Power Cable Assembly

Product Overview:
The CP306260 is a Kollmorgen-specific power cable assembly designed for connecting AKD series servo drives to 3-phase AC mains power and to the servo motor. It is a pre-terminated, factory-tested cable assembly that ensures optimal EMC performance and reliable power delivery.

Detailed content

Technical Specifications:

  • Part Number: CP306260
  • Cable Type: 3-phase + PE (4-core) power cable
  • Conductor Size: 6 mm² (approximately — verify exact gauge from datasheet)
  • Voltage Rating: 600/1000V
  • Current Rating32A (typical for 6 mm² copper)
  • Cable Length: Factory-specified length (commonly 3m or 5m — verify exact length from part number decoding)
  • Connector (Drive End): Kollmorgen proprietary power connector or IEC 60309 (depending on region)
  • Connector (Mains End): IEC 60309 blue (230V) or red (400V) industrial plug
  • Shielding: Overall braided copper shield (drain wire included)
  • Insulation: XLPE or silicone rubber (high-temperature rated)
  • Outer Jacket: PUR (polyurethane) — oil and abrasion resistant
  • Bend Radius: Minimum 5× cable diameter
  • Temperature Range: -20°C to +80°C (continuous), +120°C (short term)
  • Protection Rating: IP67 (with connectors mated)

Material Composition:

  • Conductors: Oxygen-free high-conductivity (OFHC) copper, Class 5 (flexible)
  • Insulation: Cross-linked polyethylene (XLPE) — Class B (130°C)
  • Shield: Tinned copper braid (coverage >85%)
  • Jacket: Polyurethane (PUR) — abrasion, oil, UV resistant
  • Connectors: Nickel-plated brass housing, silver-plated copper contacts

Structural Features:

  • Pre-terminated at both ends — no field termination required
  • Drain wire with ring terminal for chassis ground
  • Flexible construction — suitable for moving cable carriers (if rated for dynamic use)
  • Color coding per IEC 60446: Brown (L1), Black (L2), Grey (L3), Green/Yellow (PE)

Working Principle:
The cable delivers 3-phase AC power from the mains supply to the servo drive’s rectifier input stage. The built-in EMI shield prevents high-frequency switching noise from the drive’s IGBT inverter from radiating back onto the mains supply, ensuring EMC compliance (EN 61800-3). The drain wire provides a low-impedance ground path for shield current.

Key Advantages:

  • Factory-terminated — eliminates field wiring errors
  • EMC-optimized — meets EN 61800-3 Category C3 (or higher)
  • High flexibility — PUR jacket resists oil, abrasion, and repeated flexing
  • Reliable connections — industrial-grade connectors with IP67 rating
  • Kollmorgen-validated — tested with AKD drives for optimal performance

Applicable Industries:

  • All AKD drive installations
  • CNC machines
  • Robotics
  • Packaging equipment
  • Any Kollmorgen servo system

Installation Requirements:

  • Route cable away from signal/encoder cables (min 100 mm separation)
  • Use cable clamp at drive end and mains end
  • Connect drain wire to cabinet ground bar (both ends if long run)
  • Do not exceed minimum bend radius
  • Do not run cable parallel to high-current welding cables

Usage Notes:

  • Replace entire assembly if damaged — do not re-terminate in the field
  • Verify connector keying matches drive and mains supply
  • For dynamic applications, confirm cable is rated for cable carrier use (CP series with “DYN” suffix)
  • Store coiled (not kinked) in dry environment
