Product Description:
The KDS 1.3-150-300-W1/S102 servo-drive module is produced by Bosch Rexroth Indramat within the KDS Servo Drive Modules series. This module interfaces between the DC bus of a supply unit and the motor phases, modulating current so commanded torque and speed profiles are followed accurately. By converting the DC link voltage into regulated three-phase output, it supports precise positioning, controlled speed changes, and braking in packaging lines, transfer systems, gantry axes, and other automated machinery. Its role in the drive system allows the connected motor to respond quickly to changing load demands while maintaining stable motion.
This unit supports a continuous output current of 96 A, allowing sustained motion during nominal duty cycles without thermal derating. The unit has both a peak output current and a rated output current of 150 A, giving short-term overload capacity for rapid acceleration while matching inverter sizing. The internal power electronics are referenced to a DC link level of 300 V (±15%), so the incoming bus must remain within that range for stable pulse-width modulation. With a maximum power transfer capability of 45 kW, the module can drive medium-frame servomotors used on extrusion screws or press feeders. Cooling uses forced ventilation, which moves cabinet air across the heat sink and helps maintain steady thermal performance during repeated load changes.
Airflow is provided by the dedicated LE4 external fan unit mounted to the top plate and aligned with the module's duct channels. At 15.4 kg, the enclosure adds limited mass to the panel and can be mounted directly on a backplane without excessive structural demand. The product is identified as Model 3, indicating a specific connector and module revision within the range. It is part of Series 1, which uses the first mechanical layout of the KDS family. This layout supports predictable placement of bus bars, power terminals, and diagnostic connections inside the cabinet.
