Product Description:

The KSM02.1B-061C-35N-S3-HP2-ET-NN-D7-NN-FW is manufactured by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. By merging a servo motor and drive electronics in the same enclosure, this motor-integrated servo drive trims cabinet space and simplifies machine wiring. This layout keeps the power electronics close to the driven axis and reduces the amount of long motor cabling inside the cabinet. It is intended for decentralized mounting next to the axis it actuates, where it executes closed-loop positioning and speed tasks for industrial automation lines.

The drive accepts a DC bus of DC 750 V, delivered from a central supply module. Power, control, and safety conductors are routed through a single Hybrid Connector, so one plug handles all wiring. Heat is removed through natural convection, which eliminates fans and helps reliability in dust-laden areas. Command and diagnostic traffic move over a Multi-Ethernet interface that supports several real-time fieldbus protocols without extra hardware. Rotor position is returned through a Hiperface feedback channel, and the capacitive sensor inside the motor produces 16 signal periods per electrical revolution, giving sufficient resolution for moderate-accuracy motion profiles.

The spring-applied brake is released at DC 24 V, allowing power-off holding on vertical axes. Mechanical sizing follows a frame code of 061, so shaft height and flange geometry match other drives in that group. The unit is supplied without safety technology, so any STO or SS1 function must be handled by upstream devices. Additional attributes include a standard design option, design version 1, a single-turn capacitive encoder, motor length C, winding code 35, a basic performance level, series number 2, a shaft with keyway, and a shaft seal that helps keep lubricants out of the bearing cavity.
