Product Description:

The KDS 1.1-050-300-W0-220/S102 is a servo-drive module produced by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. It links a DC bus to an Indramat motor axis and supplies controlled current and voltage for closed-loop torque control in automated equipment. This arrangement allows the module to support precise motion on machinery that depends on stable servo response during changing load conditions. The unit is hardware version 1 with internal series code 1, placing it within the matching platform configuration for this product line.

During continuous operation, the module delivers 35 A to the connected motor, while short acceleration demands can be supported with a peak output of 50 A. The internal bus maintains a link-circuit potential of 300 V DC ±15%, giving the inverter stage a stable energy source during axis movement. The power stage is rated for 15 kW, which suits mid-range servo axes used in packaging, printing, and material-handling systems. Heat is removed by natural convection, so the module does not rely on an internal forced-air assembly. A separate fan terminal is included for applications that need additional cabinet airflow from an external blower.

The fan connection accepts AC 220 V, 50–60 Hz, which supports common auxiliary cooling equipment used in control cabinets. Safe operation is supported across an ambient range of +5 °C to +45 °C, making the module suitable for most indoor industrial environments. Ingress protection is limited to IP 10, so the drive must be installed inside a closed electrical cabinet that shields it from dust and accidental contact. The unit weighs 14.1 kg, which is suitable for standard cabinet mounting arrangements. Its mass is moderate enough for typical panel structures while still reflecting the size of the power section inside the housing.
