Product Description:

The IKG4056 is a pre-engineered motor power lead produced by Bosch Rexroth Indramat as part of the IKG Motor Power Cables series. It links a drive controller to the stator terminals of an Indramat motor, supplying three-phase mains energy while maintaining shielding continuity. Factory-attached connectors and tested insulation shorten cabinet assembly and commissioning time on automated production lines. The construction targets harsh motion environments where vibration, oil mist, and repeated axis travel place high demands on cable integrity.

As a Power Cable (Ready-Made) assembly, the IKG4056 arrives in a finished length with both ends stripped, crimped, and strain-relieved, so installers only route and fasten the harness. The conductor bundle follows the INK0669 core specification, so copper cross-sections and shielding are matched to Indramat drive currents. External abrasion resistance comes from a PUR outer jacket that withstands cutting fluids and tight cable tracks. The power pair is rated for 600 V, and insulation integrity is proven by a dielectric withstand of 4000 V on those conductors. Supply cores can also operate at 600/1000 V, giving compatibility with international mains classes.

Service life is aided by modest bend limits; in motion the cable flexes to 10×D, while fixed routing allows 6×D without damage. Thermal resilience spans machine and climate extremes: during continuous movement it stays flexible from -30 to +60 °C, and when stationary it tolerates -50 to +80 °C. An INS0681 motor-end connector mates directly with Indramat terminal boxes, preserving EMC bonding and sealing. These mechanical and thermal margins permit repeated carrier-chain travel without compromising electrical clearance or retention.
