2301, Power and feedback cable

Special Cables for Servo Application

Motor cable – double shielded low capacitance cables of flexible design, with PVC sheath and PE core insulation. Longer cable connection possible between frequency converter and drive due to low capacitance design. 3+3 symmetry reduces common-mode interference effects.

Screen - double screening with aluminium coated plastic foil (metal side outwards) and braid of tinned copper wires, braid coverage min. 70% (nominal value)

Number of wires - 3x2.5 mm power wire + 3 x 0.5 ground wire

Outer diameter – 12.9 mm

Nominal voltage - 600V

Maximum voltage – 4000V

Feedback cable

High flexible, screened, oil4resistant, halogen free, signal (encoder and resolver) cables with an outer sheath of Polyurethane.

Screen – braid of tinned copper wires, coverage = 85% (nominal value)

Number of wires – 9 x 0.25 mm

Nominal voltage – 30V

Maximum voltage – 750V
