Product Description:
The KSM01.2B-041C-42N-S1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining the motor, power stage, and control electronics in one housing, it reduces cabinet space and shortens cable runs in conveyor, packaging, and handling equipment. Classified at the basic performance level, the device provides closed-loop position and speed control to decentralized axes that share a common DC bus in industrial automation lines. Its compact integrated layout also allows the drive to be mounted close to the driven axis, which helps keep machine wiring organized.
Electrical power enters the unit through a DC 750 V intermediate circuit. Heat is removed by natural convection, so the drive operates without fan-based cooling. Network commands are transmitted over SERCOS 2 (RS422), which supports cyclic synchronized updates for multi-axis machines. Position data is handled through a Hiperface optical encoder interface, allowing the controller to receive feedback and operating data over a compact connection. A shaft seal protects the front bearing area from coolant splash and airborne contamination. This arrangement supports installation in machinery where the axis drive must remain close to moving assemblies while still exchanging real-time control data.
Power, feedback, and brake lines are consolidated in a Hybrid Connector, which simplifies cable routing along machine frames. The optical encoder provides 128 signal periods per revolution and uses single-turn position detection, so the absolute position is retained within one full rotation. Mechanical output is transmitted through a shaft with a keyway that mates with keyed couplings for positive torque transfer. The mechanical design follows the standard option and corresponds to design version 2. The housing uses motor size 041 with the compact C length, making it suitable for tight installation envelopes. Because the drive is supplied without a holding brake, any vertical load must be secured by external clamping.
