IKG0012 by Bosch Rexroth Indramat

The IKG0012 cable is manufactured by Bosch Rexroth Indramat and belongs to the IKG Motor Power Cables series. It is used as a combined power and control lead for servo and spindle motors, allowing both the high-current phases and auxiliary sensor lines to be routed through a single jacket. Used inside drag chains or machine frames, the cable supports coordinated axis motion by providing stable electrical paths between the drive inverter and the motor terminals, even under constant acceleration.

The power circuit is formed by 4x1.0 mm² conductors and is insulated for a phase-to-phase working voltage of 300/500 V, so the cable can be used on low-voltage servo drives without additional shielding. Distributed capacitance of 0.6 nF/m limits reactive current at high switching frequencies, while a direct-current loop resistance of 19.5 ?/km keeps voltage drop modest on typical machine lengths. When the cable is clamped to a stationary track, the minimum static bend is 5 x D; with the stated outer diameter of 12.0 mm, this corresponds to a 60 mm loop, reducing stress on copper strands. Rated control pairs carry 300/300 V logic signals, and the PUR jacket is certified for continuous movement inside drag chains.

Two shielded signal pairs, specified as 2x(2x0.75 mm²), provide brake or temperature inputs and are color-matched to the three-phase cores for quick termination. The sheath color is RAL 2003 (orange), aiding visual separation from pneumatic hoses, and the matte, adhesion-free surface is molded from PUR to resist oil and weld spatter. During dynamic operation, the cable endures more than 5,000,000 flex cycles with a bend radius of 7.5 × D, and its class-E insulation tolerates conductor temperatures up to +90 °C in fixed routing. The cable maintains power and signal continuity while machines accelerate, reverse, and index in short duty cycles.
