Product Description:
The KSM02.1B-061C-35N-M1-HG2-ET-L3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It combines a permanent-magnet servo motor and a drive amplifier in one housing, which reduces cabinet wiring and allows installation close to the driven axis. The unit is intended for decentralized motion applications where compact hardware controls torque and speed near the load. This arrangement suits packaging, material-handling, and assembly equipment that uses standard positioning and velocity control. The motor section uses frame size 061 with length C, helping the housing fit into compact machine layouts.
Power is supplied through a nominal DC 750 V bus, so the integrated inverter operates from a common DC link rather than an internal rectifier stage. All power, feedback, and network connections pass through a single Hybrid Connector, which simplifies cable routing at the machine. Heat is removed by natural convection, so no fan or liquid cooling circuit is required. For controller communication, the unit uses Multi-Ethernet, allowing support for PROFINET, EtherNet/IP, and SERCOS III on one interface. Position data are transferred over Hiperface from the integrated optical multi-turn encoder, giving the drive the feedback needed for closed-loop operation.
The measuring system provides 128 signal periods for rotor position feedback, supporting accurate motion control across the encoder's multi-turn range. The output uses a plain shaft with a shaft seal, allowing direct connection to couplings or pulleys while helping protect the bearings from splash and dust. An electrically released holding brake operates at DC 24 V to secure vertical or suspended loads when power or drive enable is removed. For safety-related stopping, the drive includes Safe Torque Off (STO), which removes energy from the motor windings without interrupting fieldbus diagnostics. The device follows the standard design option and uses winding code 35 for the motor section.
