Product Description:

The KDS1.1-100-300-W1 is a servo drive module produced by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. Installed in a multi-axis drive rack, the unit supplies regulated DC power and switching functions to synchronous and induction servo motors so that automated tooling, material-handling, or packaging sections can maintain precise velocity and torque profiles. Its rack-based layout supports coordinated motion systems that use a shared power structure across multiple axes.

The module is rated for a continuous output of 93 A, which is the maximum current it can deliver continuously without thermal derating. Under this load, it supports up to 30 kW of continuous mechanical power when paired with matched converters. A link circuit potential of 300 VDC ties the module to the common bus, allowing energy exchange between multiple axes. Heat generated by semiconductors is removed through forced ventilation, so airflow must be maintained for stable operation. Electrical losses include 150 W internally and 400 W released to the surrounding cabinet, which affects enclosure cooling. Control electronics draw 1,450 mA from the +24 V rack supply, while the X25 logic interface sources up to 50 mA for external sensors. The drive also complies with humidity class F and insulation category C for industrial use.

Dynamic events are handled with a peak and type current limit of 100 A, allowing short bursts of acceleration within the module’s operating range. Ambient operation is permitted up to 55 °C, with current derating required above 45 °C, and functionality is maintained at mounting heights up to 1,000 m above sea level. The enclosure carries an IP10 protection rating, which indicates open-rack installation where only solid objects larger than 50 mm are excluded. At 15.2 kg, the module adds moderate mass to the drive cabinet and requires secure mounting support. These operating limits should be considered when planning cabinet airflow, vertical spacing, and overall thermal load.
