Product Description:
The KSM02.1B-061C-35N-M1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By merging a brushless servomotor with embedded drive electronics, it supplies decentralized axis control for conveyors, pick-and-place heads, and similar motion stations. The device belongs to Series 2 of the platform and offers a compact solution that reduces cabinet space on modular machines with decentralized axes.
It operates from DC 750 V supplied via the machine’s common DC bus, eliminating a separate rectifier stage at the axis. This arrangement supports a centralized power concept for multiple axes. Power, signal, and protective conductors terminate on a single Hybrid Connector, streamlining installation. Heat is removed solely by natural convection, so the housing requires free airflow without auxiliary fans. The drive body matches motor size 061, motor length C, and winding code 35, and these values correspond to the motor’s magnetic layout and continuous torque range. Internal position feedback resolves the rotor every 128 signal periods, giving fine granularity for current vector control. The unit uses the standard design option, design version 1, and the Basic performance level. It is delivered without a holding brake, and a shaft seal helps prevent fluid ingress.
The encoder section uses a Hiperface interface with optical scanning, sending analog sine-cosine tracks and digital data through the same cable. This arrangement supports precise commutation and stable speed control during motion. It delivers multi-turn absolute position data, removing the need for homing after power cycling. Control commands and diagnostics reach the drive through Multi-Ethernet, covering common industrial Ethernet variants without additional hardware. Mechanical torque is transferred through a shaft with a keyway, allowing positive engagement with pulleys or gear sets.
