Product Description:

The KSM02.1B-041C-42N-S1-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By combining motor, power electronics, and feedback in a single housing, it supplies decentralized axis control for packaging, printing, or material-handling machines where cabinet space is limited. The unit’s mechanical format corresponds to motor size 041 and length code C, making it suitable for moderate torque demands within distributed automation layouts.

Power for the drive is supplied from a DC bus at DC 750 V, a level that allows long cable runs between cabinet converters and field-mounted drives without significant voltage drop. All power, signal, and safety conductors are combined in a Hybrid Connector, simplifying installation through a single pluggable interface. Heat generated by the electronics is removed through natural convection, so no fans or liquid loops are required. Position feedback is transmitted through a Hiperface encoder that delivers 128 signal periods per revolution, yielding fine commutation and stable velocity control even at low speeds.

For machine safety, the drive integrates Safe Torque Off, which disconnects gate power to the motor when the circuit is tripped and eliminates residual motion without relying on mechanical parts. Its control electronics support Multi-Ethernet communication, allowing the same hardware to join EtherNet/IP, PROFINET, EtherCAT, or Sercos III networks based on configuration. Mechanical coupling to the load is provided by a shaft with keyway, giving positive torque transmission in belt or gear applications; because the assembly is delivered without a holding brake, an external locking device is required when vertical loads must be maintained during power-off conditions.
