Product Description:

The KDS 1.1-050-300-W0-115/S102 is a servo-drive module built by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. It functions as the power interface between a supply unit and an Indramat servo motor, regulating DC-link energy so the motor receives precise current and voltage for motion tasks in automated machinery and material-handling lines. The unit is intended for coordinated axis control, where stable current regulation supports repeatable speed and position response during starts, stops, and direction changes. Its module format also fits cabinet-based drive systems that separate the power supply from the motor axis electronics.

This module delivers a continuous current of 35 A, so it can supply steady torque in applications that demand sustained load control. Heat is removed by natural convection, eliminating the need for forced-air channels inside the cabinet. A separate housing fan operates on AC 115 V, 50/60 Hz to move ambient air across the heat sink when panel airflow is limited. The internal link circuit works from a nominal 300 V DC bus with an allowable variation of ±15%, helping the drive remain stable during moderate line changes. During short accelerations, the power stage can deliver a peak current of 50 A, and that value is also used for sizing protective components and motor cables. The permitted ambient operating range is +5 to +45 °C, which suits standard factory enclosures without supplemental conditioning.

Total power output reaches 15 kW, matching medium-frame servo motors used on indexing tables, gantries, and converting lines. The housing carries a protection rating of IP 10, so the module should be installed in a closed control cabinet to limit contact with dust and exposed internal areas. With a mass of 14.1 kg, the unit can be mounted on a rigid backplate or comparable cabinet support without unusual handling requirements. Design identifiers such as Model 1 and Series 1 distinguish this version within the product line, and the servo-drive module layout supports organized integration with compatible supply and control assemblies.
