Product Description:
The KDS 1.1-050-300-W1 servo-drive module is produced by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. As a drive controller, it converts the 300 V DC link energy into three-phase stator currents so that Indramat servo motors can be governed within multiaxis machining centers and material-handling cells. The module belongs to model version 1 and is intended for cabinet installation with forced-air assistance. Bosch Rexroth also labels this hardware as series 1.
Electrical output is defined by a continuous current of 50 A, which is also the rated and peak current limit for this model. That current supports a shaft power of 15 kW when the link circuit delivers 300 V DC (±15 %). The drive interprets command signals through a current set-point gain of 0.150 V/A, while fine tuning can begin at the minimum adjustable level of 2 A. Control electronics draw 950 mA from the 24 V logic supply, plus 140 mA from the +15 V rail and 50 mA from the –15 V rail, assuring stable reference generation for current loops. Forced ventilation is the stated cooling type, and the external fan unit designated LE4 mounts to the module in the direction of airflow.
The heat removed by the LE4 blower equals an external power loss of 220 W; internally the electronics dissipate an additional 85 W that is routed through the same airflow path. Ambient operation is permitted between +5 – +45 °C, and the housing carries a protection rating of IP 10, so it must be located inside a closed electrical cabinet. The drive module itself weighs 14.4 kg, the fan unit adds 4.2 kg, and its assembly kit contributes 1.7 kg to the installed mass. Overall power output is declared at 15 kW, synchronized with the link circuit voltage already stated, while continuous current remains at 50 A. Cooling is specified as forced ventilation, consistent with the external fan arrangement.
