Product Description:
The KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. The unit combines a permanent-magnet motor, inverter stage, and network interface in one housing, which allows decentralized installation on moving machine parts. By placing the power electronics directly on the axis, it reduces cabinet wiring and shortens encoder runs, making it suitable for modular handling systems, packaging stations, and light assembly lines where space and cabling weight are limited.
The drive accepts a bus voltage of DC 750 V, which allows direct connection to shared DC-link supplies in multi-axis systems. Heat is removed through natural convection, so the housing requires free airflow and does not use an additional fan. Power, safety, and feedback lines are combined in a single Hybrid Connector, which simplifies cable routing and reduces flex points on moving axes. Integrated functional safety is provided by Safe Torque Off (STO), so the output stage is disabled when the safety channel is activated and the motor cannot produce torque. Rotor position and speed are transmitted through a Hiperface interface, which works with the integrated multi-turn encoder to provide absolute position data after a power loss.
The encoder resolves shaft motion into 16 signal periods per revolution and tracks turns through an internal gearing mechanism. A shaft seal helps protect the plain shaft against splashing fluids, which supports use in washdown areas when suitable external sealing is applied. Stator winding code 61 is matched to the embedded inverter, and the compact frame size 061 with motor length C keeps the package small for decentralized axes. Multi-Ethernet communication allows operation on EtherNet/IP, PROFINET, SERCOS III, or EtherCAT without hardware changes. The unit has no holding brake, so static load retention must be provided by external mechanics, and it uses a plain shaft for rigid couplings in low-inertia applications.
Frequently Asked Questions about KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW:
Q: What kind of connection type does the KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW servo drive utilize?
A: The KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW servo drive uses a hybrid connector for its electrical connections.
Q: What cooling method is employed by the KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW drive?
A: This model operates with natural convection cooling, so it does not require external fans or forced cooling systems.
Q: What kind of output coupling design option is provided on the KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW?
A: The KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW features a multi-Ethernet output coupling for versatile network connectivity.
Q: What type of encoder and resolution does the KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW have?
A: The encoder interface uses Hiperface technology and supports multi-turn absolute position detection with 16 signal periods of resolution.
Q: Does the KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-TO-FW include a holding brake?
A: This servo drive is designed without a holding brake, so it does not offer motor shaft holding when powered off.
