Product Description:
The KSM01.2B-041C-42N-S1-HP2-SE-NN-D7-NN-FW is a motor-integrated servo drive from the KSM Motor Integrated Servo Drives series manufactured by Bosch Rexroth Indramat. By combining drive electronics, feedback, and the 041 frame motor in one housing, it provides decentralized axis control for material handling stations, packaging modules, and small assembly cells where cabinet space is limited. The integrated layout reduces the need for separate motor and drive hardware at the machine, and it helps keep cable routing short and orderly. During operation, the motor and electronics function as one axis package, which supports compact installation in distributed automation layouts.
This unit operates from a bus supply of DC 750 V and dissipates heat through natural convection, so no external fan or liquid circuit is required. All power, signal, and brake lines are consolidated in a single hybrid connector, which simplifies routing in daisy-chain layouts and reduces the number of separate connections at the axis. Command and diagnostic data are exchanged over SERCOS 2 on an RS-422 physical layer, while position feedback is provided through Hiperface. The unit is version 2 with the standard design option and a Basic performance level, and the motor size 041 with length code C suits mid-range indexing axes.
The electrically released brake is energized by DC 24 V to hold position during power loss or emergency stops, and it releases automatically when torque is enabled. A permanent shaft seal keeps lubricant in the bearing area and helps block coolant spray, while the keyed shaft couples directly to pulleys or couplings. The drive is supplied without safety technology. The optical encoder uses a single-turn format with 128 signal periods, and winding code 42 sets the electrical constants used by the drive electronics.
