Product Description:

The KSM02.1B-061C-61N-S1-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servo motor and drive electronics in one enclosure, it lets designers place decentralized motion control directly on the machine frame. The unit therefore delivers closed-loop speed and position regulation for packaging stations, pick-and-place axes, and other coordinated automation tasks.

This drive operates from a DC 750 V bus and routes power, feedback, and network signals through a single Hybrid Connector, reducing cabinet wiring. Internal heat leaves the housing through natural convection, so no fans or liquid cooling are required when clearance guidelines are met. Real-time control data move over Multi-Ethernet, allowing protocol selection in the PLC without changing hardware. The optical incremental encoder generates 128 signal periods per revolution, giving fine velocity resolution under closed-loop control. The unit has size 061 stator laminations, length code C, and winding code 61, which correspond to its mechanical envelope and torque-speed behavior. The shaft has a keyway for positive coupling, and a shaft seal is fitted to block dust or coolant. This is Version 1 of the standard design with a basic performance level.

Machine safety is handled by the integrated Safe Torque Off (STO) channel, which removes drive gate signals so no torque can be produced after an emergency stop command. Absolute position is transferred through the Hiperface interface; because the sensor is single-turn, the controller determines rotor angle within one revolution while upper-level software tracks multi-turn position if needed. An electrically released holding brake clamps the shaft whenever control power is lost and disengages when DC 24 V is applied, allowing reliable load retention.
