Product Description:

The KSM02.1B-041C-42N-M1-HG2-ET-NN-D7-TO-FW is a motor-integrated servo drive from Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. This compact unit combines a 041 frame synchronous motor, power electronics, and network interfaces in one enclosure, allowing it to mount directly on moving machine elements. In an automation cell, it provides decentralized speed, position, and torque control while reducing cabinet space and cabling compared with traditional cabinet-mounted drives. Because the inverter and motor share one housing, the unit suits decentralized machine layouts where long motor cables are not preferred.

During operation, the drive accepts a supply of DC 750 V, enabling it to share a common DC bus with other axis modules and return braking energy to that bus. Field wiring is simplified by the single hybrid connector, which carries power, control, and safety signals in one shielded lead. Heat generated by the inverter is removed through natural convection, so no external fans or liquid cooling equipment are required in the installation. Network traffic is handled through the drive's Multi-Ethernet output coupling, letting it connect to EtherNet/IP, PROFINET, or EtherCAT masters without additional gateway hardware. This communication arrangement lets the axis exchange real-time commands and status data with the higher-level controller. Position data reaches the controller over a Hiperface interface, supporting rapid homing and fine interpolated motion.

The feedback device inside the housing uses optical scanning on a multi-turn disk, which helps maintain stable position measurement over the full mechanical travel. The multi-turn arrangement lets the feedback system track shaft rotation across more than one revolution. Secure load holding after a controlled stop is provided by an electrically released brake that clamps the rotor whenever control power is removed. The brake coil operates at DC 24 V, allowing direct connection to standard machine safety relays. Mechanical coupling is through a plain shaft, which simplifies integration with custom hubs or pulleys and suits clamping elements that do not require a keyed connection.
