Product Description:

The KSM02.1B-041C-42N-M1-HP0-ET-L3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics, the power stage, and the motor in a single housing, it shortens cabinet wiring and simplifies installation in distributed automation. The unit controls rotary motion on production lines, packaging machines, and handling modules where decentralized drives reduce panel space and cable runs.

Power reaches the drive through a single Hybrid Connector that carries the DC supply and fieldbus signals, so no additional feedback line is required. Heat produced by the power electronics is removed through natural convection, and this passive method eliminates fans. The internal converter operates from a DC 750 V link that is supplied by an IndraDrive power supply module. Position data come from an optical encoder that communicates over Hiperface. The encoder provides 128 signal periods per mechanical revolution, giving fine interpolation for tight position loops. It also stores absolute position across power cycles, letting the axis reference itself without homing. Because the motor is supplied without a holding brake, any static load must be secured by external mechanics or closed-loop torque.

The multi-protocol interface uses Multi-Ethernet communication, so Profinet, EtherNet/IP, EtherCAT, or Sercos III can be selected to match the control network. A dedicated safety channel implements Safe Torque Off (STO), removing gate-drive energy when the controller issues a stop. The drive has a basic performance level for standard duty cycles. Mechanical power is transmitted through a shaft with a keyway, and a shaft seal helps prevent ingress. The motor uses size 041, length C, winding code 42, optical multi-turn technology, and design version 1.
