Product Description:

The KSM02.1B-071C-24N-S1-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By merging a servo motor, power stage, and fieldbus node in one housing, it saves cabinet space and simplifies wiring on distributed industrial axes. This integrated layout places the drive electronics close to the motor, which reduces the amount of separate cabinet hardware needed for each axis. It is suited to machine layouts where decentralized axis modules are preferred over long motor cable runs. The device belongs to design series 2 and version 1, and it is intended for positioning or speed-controlled duties in packaging, material handling, and general automation lines.

The drive operates from a nominal bus voltage of DC 750 V, allowing energy sharing with other axes on the machine DC link. Motor power, encoder, and optional brake conductors are combined in a single Hybrid Connector, which simplifies wiring between the unit and the machine. Cooling relies on natural convection, so no fan is required when the specified mounting clearances are observed. Position data comes from an optical single-turn encoder that uses Hiperface communication and delivers 128 signal periods per revolution, supporting precise electronic gearing. The motor section corresponds to length C with winding code 24, and the assembly is supplied without a holding brake, so external load-holding measures may be required.

Machine safety is addressed by Safe Torque Off (STO), which disables the power elements internally while keeping diagnostics active. This arrangement allows the control system to retain status information after torque has been removed. Field communication is handled by the Multi-Ethernet interface from the design option, enabling use with major Ethernet-based protocols without hardware changes. The motor uses a plain shaft with a shaft seal, and the mechanical frame is classified as 071, matching standard KSM accessories. The Basic performance level suits axes that still need deterministic motion.
