Product Description:
The IKG4008 cable is a motor power cable produced by Bosch Rexroth Indramat within the IKG Motor Power Cables series. It serves as the fixed or dynamic connection between an IndraDrive amplifier and a synchronous servo motor, carrying motor power together with auxiliary control cores inside one jacket. This combined layout reduces the need for separate parallel runs between the drive and the motor. Used in energy chains and machine gantries, the cable is intended for repetitive movement while maintaining reliable electrical performance in industrial automation cells. It is suited to axes that cycle frequently and require stable current delivery during travel.
The PUR jacket resists oil and abrasion, and the cable is rated for 5,000,000 bending cycles with a minimum dynamic bending radius of 7.5 × D. It has an outside diameter of 12.0 mm and contains four 1.0 mm² power conductors that fit standard chain separators. A separate pair for encoder or brake signals has a 0.75 mm² cross-section, allowing the same routing path without an additional cable bundle. This arrangement keeps the moving cable package compact in drag-chain systems. Power insulation is rated for 300/500 V, while the control pair operates at 300/300 V.
Electrical characteristics include a distributed capacitance of 0.6 nF/m and a conductor resistance of 19.5 Ω/km, which help limit reactive effects and voltage drop along the run. Stable transmission is important on longer cable paths where drive output and auxiliary signals share the same assembly. The cable remains flexible down to -30 °C and is intended for ambient temperatures up to +40 °C. In fixed routing, the conductor insulation tolerates +90 °C, while in motion the conductor temperature is limited to +80 °C. The fixed-routing limit and moving limit are applied separately because flexing places more stress on the conductor insulation during operation.
