KSM02.1B-061C-61N-M3-HP2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M3-HP2-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a motor, drive electronics, and feedback components within one enclosure for decentralized motion control in automated packaging, handling, and assembly equipment. The integrated arrangement permits direct machine mounting, shortens cable runs between the motor and drive, and reduces the amount of equipment required inside the control cabinet.

This model operates from a shared DC link at 750 V DC, allowing connected axes to exchange energy through a common power bus. Its power stage is cooled by natural convection, eliminating the need for a cooling fan or liquid circuit. Network traffic is carried over Multi-Ethernet, so the communication hardware can support EtherNet/IP, PROFINET, or EtherCAT without rewiring the unit. Rotor position is transmitted through a Hiperface interface connected to a capacitive, multi-turn absolute encoder that provides 16 signal periods per revolution. The encoder retains position information across multiple shaft revolutions and supports controlled motion immediately after startup. The drive uses the standard design option, design version 1, and the Basic performance level. Integrated safety technology is not included.

A hybrid connector carries the DC bus, logic power, and fieldbus lines through one connection, reducing the number of separate machine cables. The electrically released holding brake engages when power is removed and is released with a 24 V DC command. This brake arrangement can prevent an unpowered vertical axis from moving under its load. Output torque is transmitted through a shaft with a keyway, which provides positive engagement with a compatible coupling or gearbox. A shaft seal helps prevent coolant and dust from reaching the internal bearing area. The motor has size 061 and length code C, while winding code 61 identifies the electrical configuration used with its drive stage. The product belongs to internal series 2.
