Product Description:
The KSM02.1B-061C-35N-S1-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive developed by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. As a compact axis controller, it unites a permanent-magnet synchronous motor, power electronics, and real-time networking in one enclosure, enabling distributed motion control in packaging lines, handling robots, and assembly cells. Integrating the drive at the machine frame eliminates long motor cables and frees cabinet space for other automation hardware. This layout also reduces the amount of separate wiring that must be routed between the control cabinet and the moving axis.
The drive draws power from a DC 750 V bus, so regenerated energy from adjacent axes remains available to the machine. A single Hybrid Connector carries the DC link, signals, and feedback, which simplifies installation to one plug. Thermal management uses natural convection, eliminating fans and filters. Control data moves over Multi-Ethernet, so the unit can use supported real-time Ethernet variants without hardware changes. In an emergency, the integrated Safe Torque Off (STO) stage blocks inverter gating to prevent torque. The Standard design option and Version 1 identify this unit as the basic build in Series 2. Motor size 061, length code C, and winding code 35 match the Basic performance level for medium-duty shafts. The combined motor-and-drive format supports decentralized installation where compact wiring and a small machine footprint are important.
Position feedback is produced by an optical Hiperface encoder that offers 128 signal periods per revolution and operates in a single-turn range, giving the controller the absolute rotor angle after each power cycle. A shaft seal is fitted to protect the bearings when the shaft with a keyway couples to lubricated gearboxes. The integrated brake is electrically released and holds the load whenever the control electronics remove its DC 24 V coil supply, securing vertical axes without motor torque. This arrangement keeps holding force inside the motor assembly instead of relying on a separate external device.
