Product Description:

The KSM01.2B-071C-24N-M1-HP2-SE-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 size 071 synchronous motor, a power inverter, and a fieldbus interface in one housing so the axis can mount directly on the machine frame. This arrangement shortens motor and control cabling and places the drive electronics close to the moving axis. The unit is design version 2 with a standard mechanical option, uses motor length C, and is intended for basic performance tasks. It fits decentralized machine layouts in compact automation cells where cabinet-mounted axes would otherwise require longer cable runs.

The drive operates from a nominal DC 750 V bus, allowing it to share a common DC link with other axes. Command data reach the controller through SERCOS 2 (RS-422), which supports deterministic cyclic setpoint exchange. Heat is removed by natural convection, so the unit does not require an internal fan. Rotor position is returned through a Hiperface interface from an encoder with 128 signal periods per revolution. The encoder is a multi-turn absolute type, allowing the drive to retain position information across multiple shaft revolutions after power loss without an external battery.

An electrically released brake rated at DC 24 V holds the load when power or control is removed, and its status can be monitored through the line terminated by a hybrid connector. Output torque is delivered through a shaft with keyway, and a shaft seal is fitted to help limit dust or coolant ingress. The keyed output supports positive torque transfer to couplings or gearbox inputs used on the machine. The drive is categorized as without safety technology, so applications that require safe motion functions need external safety circuitry. Series code 1 and winding code 24 identify the electrical configuration used for this distributed servo module.
