Product Description:
The KDS1.1-30-300-W0 servo-drive module is built by Bosch Rexroth Indramat and belongs to the KDS Servo Drive Modules series. Installed in multi-axis automation racks, the unit conditions DC power and feeds controlled current to synchronous motors, forming the interface between the shared supply module and individual axes. Its role in industrial automation is to translate motion commands from the controller into precise torque and speed while shielding the motor windings from overcurrent and voltage transients. Because the device handles the power conversion stage, it is typically installed next to feedback interface cards inside the cabinet.
The power channel can furnish a continuous output of 25 A, allowing the module to supply motors that absorb up to 9 kW under rated load. Energy is drawn from a common rail maintained at 300 VDC, so the drive must be paired with a compatible supply unit. For acceleration peaks, the current may rise briefly to 30 A without tripping the electronic monitors. During operation, the heat sink must dissipate 130 W of external losses, and passive fins with natural convection remove this heat without fans. The signal electronics consume 750 mA from the cabinet's +24 V control bus and should be included in the auxiliary power budget.
Additional thermal loading is produced by an internal power loss of 60 W, which remains inside the enclosure and contributes to cabinet heat. Full output is available up to an ambient temperature of 55 °C, and operation above that value requires derating. Installation altitude should not exceed 1000 m so air cooling remains effective. The aluminum housing weighs 14.1 kg and carries an IP10 ingress rating, so it must be installed in a closed electrical enclosure. Auxiliary terminal X25 can provide 50 mA at +24 V and 15 mA at ±15 V for encoders or small sensors, allowing local signal support without extra wiring.
