Product Description:

The KDS 1.3-200-300-W1 is a servo-drive module manufactured by Bosch Rexroth Indramat and supplied in the KDS Servo Drive Modules series. This module forms the power section of an Indramat drive stack by converting rectified DC-link energy into controlled three-phase current for synchronous or induction motors. It is used in conveying, packaging, and machining systems where accurate current regulation supports stable speed control, repeatable acceleration, and consistent response to changing loads. Because it serves as the power section rather than a standalone supply, it works within a larger drive assembly that distributes bus energy to individual axes.

The drive can conduct up to 200 A of current, which sets the continuous output range available to the connected motor during acceleration and load changes. Its intermediate circuit is stabilized at 300 V (+/-15%) DC, providing a shared bus potential for multiple drives mounted on the same rail. Thermal management uses forced ventilation, with airflow directed across the internal heat sinks to reduce semiconductor derating as cabinet temperature rises and to support sustained operation under heavier demand. This DC bus arrangement supports multi-axis layouts in which several modules draw from the same rectified supply rather than from separate power sources.

An external fan assembly marked LE4 attaches to the housing and is powered separately from the main power stage. The blower requires 220 VAC and accepts 50/60 Hz line frequency, so it can be supplied from common control power in either North American or European facilities. The unit is identified as Model 3, and this version uses control signaling that is compatible with SERCOS and PROFIBUS controller environments for coordinated drive operation and routine diagnostic exchange within the control system. The separate cooling circuit also allows airflow to continue independently of motor power demand, which helps remove residual heat from the module after high-load operation.
