Product Description:

The KDS 1.1-030-300-W0-220/S102 is a servo-drive module produced by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. As part of a decentralized drive system, this unit converts shared DC-bus energy into controlled three-phase output for an attached motor, allowing closed-loop speed and torque regulation in automated lines, material handling systems, and packaging machinery. In operation, it serves as the power stage between the DC supply section and the motor, responding to drive commands with regulated output current. The module follows the series 1 mechanical format and model 1 control architecture, so it fits the established KDS rack layout used for this product line.

Electrical performance centers on a continuous output capability of 25 A, which is the steady line current the converter can supply without overheating. That current level supports sustained motion during normal production duty without early thermal derating. During dynamic events, the operating limit rises to 30 A, which helps the axis handle short-term load changes and acceleration demand. The internal DC link is stabilized at 300 V ±15%, providing the intermediate voltage that the PWM inverter stage modulates. With a maximum power transfer of 9 kW, the module can drive synchronous or induction motors used on conveyors, handling axes, and similar machine functions.

The module is intended for typical factory conditions and operates in ambient air between +5 to +45 °C. This temperature range suits protected indoor installations where drive modules are mounted in enclosed equipment areas. Its enclosure has an IP 10 protection level, which provides basic shielding against inadvertent contact with live parts. At 14.1 kg, the unit mounts on standard Indramat drive racks without additional bracing. Control board ventilation can be supplemented by an external blower supplied with AC 220 V at 50–60 Hz, while normal heat removal still relies on natural convection.
