KSM02.1B-071C-35N-M1-HP0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-35N-M1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It combines a synchronous motor, inverter electronics, and safety circuitry in one housing, reducing cabinet space and wiring for decentralized machinery. The product follows design version 1, uses the standard mechanical option, and is classified as Series 2 within the platform. Its Basic performance level supports applications that use the drive's integrated control and protective functions.

The unit is powered from a 750 V DC bus, allowing direct connection to a shared DC link without an individual rectifier stage. Internal heat is removed through natural convection, eliminating the need for a cooling fan in clean environments. Position feedback is supplied through a Hiperface optical encoder that delivers 128 signal periods per revolution. Its multi-turn absolute capability retains position information across multiple shaft revolutions, allowing the controller to determine the axis position after power is restored. Motor power, logic, safety, and communication conductors are routed through a single hybrid connector, which reduces the amount of separate cabling required on modular production lines. A shaft seal protects the internal bearings from dust and fluid ingress during operation.

Real-time control data reach the drive through the Multi-Ethernet master interface, providing access to supported industrial Ethernet communication systems without an additional interface module. The motor has a frame size of 071, a frame length of C, and winding code 35, providing a suitable mechanical format for pick-and-place axes and small conveyors. Mechanical power is transmitted through a shaft with a keyway, which provides positive engagement with a compatible coupling or driven component. Safe Motion with Safe Brake Control supports monitored motion and controlled stopping functions within the drive system. The unit is supplied without a holding brake, so vertical loads require an external clamp, counterbalance, or another suitable holding mechanism when drive power is removed. Its integrated arrangement allows the drive electronics to be mounted directly with the motor rather than in a separate centralized enclosure.
