Product Description:

The IKG4203 motor power cable is produced by Bosch Rexroth Indramat as part of the IKG Motor Power Cables series. It serves as the combined power and control link between an IndraDrive amplifier and its synchronous motor, enabling energy delivery and auxiliary signal transmission in industrial automation axes. Its construction permits installation in moving cable carriers or static cable ducts, so integrators can place drives either inside cabinets or on machine frames without signal degradation.

Internally, the cable follows a 4x25.0 + 2x(2x1.5) mm² topology: four 25 mm² conductors handle the motor’s three phases plus protective earth, while two shielded pairs with 1.5 mm² cross-section carry holding-brake and temperature signals. Even with this mixed layout, the outside diameter remains 29.8 mm (±1.0 mm), allowing standard cable gland sizing. Line-to-shield capacitance is 1.1 nF/m, a value that keeps reactive current low and helps the drive meet EMC limits on longer runs. Copper conductor resistance at 20 °C is rated at 0.78 Ω/km, so voltage drop is predictable when sizing feeders. Power contacts are arranged as 3 + PE, control contacts total 7 at 1.5 mm² each, and the motor end is equipped with an INS0381/C25 circular connector for plug-in assembly.

The outer sheath is made from PUR, giving the assembly high abrasion resistance, coolant tolerance, and low halogen content. Its visibility is increased through the Orange (RAL 2003) coloring that matches standard safety conventions for energized motion cables. Mechanical handling limits are defined by a minimum bend radius of 5×D for fixed routing and 7.5×D when installed in moving drag chains, and the cable is expressly rated as suitable for continuous carrier operation. These limits help prevent conductor fatigue during repetitive motion while keeping gland and energy-guide dimensions compact.
