Product Description:

The KSM02.1B-041C-42N-M3-HG0-ET-L3-D7-ES-FW motor-integrated servo drive is produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. The device combines a permanent-magnet motor with integrated drive electronics, allowing decentralized axis control directly on the machine. It is intended for packaging equipment, pick-and-place units, and compact handling modules where installation space is limited. Mounting the drive close to the load supports distributed power layouts and reduces the need for long shielded motor cables between the control cabinet and the axis.

The unit communicates through Multi-Ethernet, so real-time motion data can be exchanged with common industrial Ethernet networks. A single Hybrid Connector carries power, safety, and feedback conductors, which helps keep wiring compact at the machine. Energy is supplied from a DC 750 V link. Rotor position is detected by a capacitive Hiperface encoder that provides 16 signal periods and supports multi-turn absolute feedback. Integrated Safe Torque Off (STO) disconnects the power stage while allowing the fieldbus connection to remain active.

Thermal management relies on natural convection, so the unit operates without cooling fans and can be used where a sealed electronic package is preferred. The motor uses frame size 041 with length code C, while winding code 42 sets the electrical characteristics for this version of the drive. The output uses a plain shaft, and an integral shaft seal helps keep lubricant away from the encoder area. Because the unit does not include a holding brake, static loads must be supported by external mechanical means or by controlled motor torque when the axis is not moving. This arrangement is suitable for applications where compact integration and direct machine-mounted installation are more important than brake-based load holding.
