Product Description:

The KDS1.1-30-300-W1 is a servo drive module produced by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. It converts shared DC-link energy into controlled phase currents for connected servomotors, enabling position and speed loops executed by the higher-level controller. The module supplies regulated power, monitors feedback, and triggers protective shutdowns when motor or bus limits are exceeded. Because it occupies a single slot, it is often combined with additional KDS units to create compact multi-axis packages used in packaging machines and transfer lines. This arrangement allows several axes to share a common power source while each module handles the current regulation for its own motor.

Thermal management relies on a mounted LE4 fan that forces air across the heat sink, and at least 80 mm of vent clearance must be left above the housing so the airflow is not obstructed. The power stage is dimensioned for a continuous phase current of 30 A, drawn from the common link that operates at 300 VDC. To connect the motor leads, the screw terminals accept a tightening load of 5 Nm, which helps prevent loosening under vibration. Mechanical integration is simplified by the compact depth of 185 mm measured with the fan shell, so the unit fits shallow control cabinets without protruding into cable ducts. The cooling layout also helps maintain stable operation in cabinets where adjacent modules are installed with limited side-to-side space.

The drive frame weighs 14.1 kg, while the detachable LE4 blower adds 4.2 kg, and the optional M1-kd wiring kit contributes a further 1.7 kg. When these components are combined with mounting hardware, the installation must not exceed 20 kg to protect rack rails and vibration isolators. At least 200 mm of free space must be reserved in front of the fan inlet so the cooling air column can develop fully and carry heat away from the heat sink. On the DC-link side, the lugs are secured at 3 Nm, and the reinforced housing helps maintain electrical integrity during load reversals and short-cycle indexing. These placement and mounting limits support reliable airflow and stable mechanical support during repeated motion cycles.
