2. Core Hardware Specifications

Connector Configuration

• Motor side: M23 12‑pin male right-angle SpeedTec DIN connector (IP65 when mated to MP motor)
• Drive side: Unterminated flying lead wires (no plug, on-site crimp to drive feedback terminal)
• Supported encoder: Sin/Cos high-resolution incremental encoder, resolver, multi-turn absolute encoder for MP rotary/linear servo motors

Cable Mechanical & Electrical

• Cable type: Continuous-flex dynamic drag-chain rated, suitable for reciprocating motion axes
• Outer jacket: Green TPE thermoplastic elastomer, oil-resistant, abrasion-resistant
• Shield structure: Double shielding (aluminum foil + copper braid), full 360° shield backshell grounding to suppress servo EMI interference
• Rated voltage: 600V signal cable
• Wire gauge: 22 AWG twisted differential pairs for encoder A/B/Z, power & temperature feedback
• Minimum bend radius: Static 6× cable OD; dynamic continuous flex 10× cable OD

4. Main Functions

1. High-precision position feedback transmission
    
   Transmit differential encoder A/B/Z pulse, resolver sine/cosine signals from MP motor back to Kinetix 6000 drive, realize closed-loop position/velocity/torque control for high-speed positioning, electronic cam, winding tension control.
2. Long-distance 60m stable signal transmission
    
   Double shielding design eliminates long-distance EMI interference, avoids position jitter, encoder loss faults in large assembly lines, printing & textile winding equipment.
3. Drag chain continuous dynamic operation
    
   Continuous-flex construction resists repeated bending fatigue, ideal for reciprocating robot axes, gantry cutting machines, packaging reciprocating stations.
4. Multi-signal integration single cable
    
   Integrates encoder differential signals, motor temperature thermal feedback, encoder power supply in one cable, simplifies cabinet wiring layout.
5. Flying lead drive-end flexibility
    
   Loose wire terminal design allows custom wiring to drive feedback terminals, adapts to special cabinet wiring layout without fixed D-Sub plug length limitation.
