Product Description:
Bosch Rexroth Indramat’s KSM02.1B-061C-35N-M1-HP0-ET-L3-D7-T0-FW belongs to the KSM Motor Integrated Servo Drives series and functions as a compact drive-motor unit for decentralized automation. The device combines a permanent-magnet synchronous motor, a servo inverter, and onboard I/O in one housing, reducing cabinet wiring in conveyor, packaging, and material-handling lines. It is built as a basic performance unit that draws its DC bus from a central supply and distributes motion commands through real-time fieldbus networks. By placing the inverter at the motor, the unit shortens local cable runs and suits machine layouts that use distributed axes.
The drive operates from a bus voltage of DC 750 V, enabling direct connection to high-power supply modules without intermediate transformers. Heat is removed by natural convection, so no fan or liquid circuit is required, and vertical mounting clearances must be maintained for airflow. Power, signals, and safety lines are routed through a single Hybrid Connector that locks with a quarter-turn motion, simplifying installation on modular machines. Position feedback reaches the integrated controller via the Hiperface serial interface, and the optical sensor produces 128 signal periods per mechanical revolution for stable speed and position control. This arrangement supports distributed machine sections that use a centralized DC supply and compact local axis wiring.
The encoder is a multi-turn absolute type, so homing after power loss is unnecessary and stored position data remains available across multiple shaft revolutions. Motion commands travel over the Multi-Ethernet port, allowing rapid change between EtherNet/IP, PROFINET, or EtherCAT without hardware changes. Integrated safety removes torque through Safe Torque Off (STO) channels that meet Category 3 requirements. Mechanical output is transferred through a shaft with a keyway, and a shaft seal helps prevent lubricant migration into the stator area. Because the unit is delivered without a holding brake, vertical axes must rely on external locking devices when the DC link is de-energized.
