Product Description:

The KSM02.1B-041C-42N-S3-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and supplied as part of the KSM Motor Integrated Servo Drives series. By combining the motor and power electronics in a single housing, the unit reduces cabinet wiring and simplifies distributed motion architectures on packaging, handling, or assembly machines. It serves the same position, speed, and torque control roles normally assigned to a separate drive controller, but mounts directly on the axis to shorten feedback paths and streamline installation.

The drive accepts a bus supply of DC 750 V and distributes that energy through a Hybrid Connector that carries power, communication, and field I/O in one plug, so a single cable can service the axis. Heat produced by the inverter stage is removed through natural convection, a passive method that eliminates fans as long as ambient airflow is available. For fieldbus integration, the controller supports Multi-Ethernet protocols, allowing it to appear as an EtherNet/IP, PROFINET, or EtherCAT node without hardware changes. Integrated Safe Torque Off (STO) disables motor power in milliseconds for emergency stops. Position feedback is relayed through the Hiperface interface, matching HCS drives and keeping encoder data synchronous with motion commands. Additional design details include winding code 42, motor size 041, length C, design version 1, series code 2, the Standard design option, and the Basic performance level.

Resolution of the sensing system is fixed at 16 signal periods per mechanical revolution, and the underlying measuring principle is the capacitive method, which resists magnetic interference common near switching devices. Because the encoder is a single-turn device, absolute position is retained over one revolution, suiting short-stroke linear mechanics and rotary tables that do not spin continuously. The mechanical output is a plain shaft with a shaft seal, so splashed coolant cannot migrate along the journal. For holding functions, the axis relies on drive torque or external clamps because it is supplied without a holding brake.
