INTRODUCTION
Our PUR shielded servo power cable is a 1:1 drop-in replacement for Siemens original 6FX5008 (MOTION-CONNECT 500 fixed installation) and 6FX8008 (MOTION-CONNECT 800 continuous flex drag chain) series motor power wires. Designed to transmit stable power and brake control signals between SINAMICS servo drives and SIMOTICS 1FK7, 1FL6, 1FT7 motors, this DESINA-compliant cable adopts VDE 0295 Class 6 extra-fine bare copper strands, double EMC shielding and wear-resistant orange PUR outer sheath. We provide pre-molded M23 motor connectors, customizable core cross-section, cable length and wire configuration, fully compliant with CE, RoHS and industrial VDE standards.

6FX8008 (PUR High Flex) vs 6FX5008 (PVC Fixed) Comparison Table
| Parameter | Our PUR 6FX8008 Equivalent (Drag Chain) | PVC 6FX5008 Equivalent (Fixed Only) |
|---|---|---|
| Outer Sheath | Polyurethane PUR (Orange RAL2003) | PVC |
| Drag Chain Suitability | Excellent (10M+ bend cycles) | Not recommended for dynamic movement |
| Oil/Coolant Resistance | Superior | Poor, easy swelling & aging |
| Low Temp Flexibility | -40℃ no cracking | Brittle below -10℃ |
| Dynamic Service Life | Long-term heavy duty | Short lifespan for moving axes |
| Best Usage | Robot, high-speed automation, machine tools | Static cabinet-to-motor fixed wiring |
FAQ
Q: What is the difference between 6FX5008 and 6FX8008 Siemens servo power cable?
A: 6FX5008 (MOTION-CONNECT 500) is PVC fixed installation cable for stationary wiring; 6FX8008 (MOTION-CONNECT 800) is PUR high-flex drag chain cable designed for millions of reciprocating bending cycles on moving machine axes.
Q: Will your servo cable trigger SINAMICS drive error codes?
A: Double full EMC shielding and identical core impedance match original Siemens specs, effectively eliminates power interference alarms like F30001, F30002 motor overload/signal faults.
Q: Do your cables include brake wires for SIMOTICS motors?
A: Standard layout comes with 2 built-in brake control cores; we support custom core configurations without brake wires upon request.
Q: What connectors can you pre-assemble for Siemens servo motors?
A: Standard straight & angled M23 motor plugs, custom crimped terminals, bare flying wire ends available.
Q: Can I get free test samples before bulk order?
A: 1–5m free testing samples are available for system verification, factory direct bulk wholesale
