IKG4060 by Bosch Rexroth Indramat

The IKG4060 belongs to the IKG Motor Power Cables series manufactured by Bosch Rexroth Indramat. It is a shielded motor power cable intended to link servo drives to synchronous or induction motors in automated machinery, carrying phase power and auxiliary signals in one assembly. It serves as the connection between the drive output and the motor on axes that cycle through frequent acceleration and deceleration. By combining four power cores with paired control conductors, the cable simplifies routing and supports coordinated motion control without requiring a separate auxiliary cable. The shield also helps reduce electrical interference along the cable route in systems that use fast-switching drive output.

The overall diameter measures 12.2 mm, and the cable contains four phase conductors sized at 4 × 1.5 mm². A tough PUR outer jacket resists oil and abrasion in moving cable chains, and fatigue life is rated for 5 million bending cycles. Each phase can carry up to 15.7 A, while conductor temperature may reach +80 °C within the permitted thermal limit of the insulation system. Two control pairs with 0.75 mm² conductors run alongside the power cores to carry brake release or thermal sensor signals. This arrangement keeps power and auxiliary circuits in one cable and reduces the need for an additional harness.

Minimum static routing requires a loop radius of 5 × D, while dynamic carrier applications need a larger 7.5 × D bend to protect the conductors during repeated motion. The separate bend-radius values account for the different stresses created by stationary loops and drag-chain travel. Operation is permitted at low ambient temperatures in fixed and moving installations, helping prevent jacket cracking in cold storage systems. The upper ambient limit is +40 °C, which matches the stated current rating for normal operation. These limits suit packaging lines, gantry loaders, and palletizers where the cable may be exposed to continuous travel and changing temperatures.
