Product Description:

The KSM02.1B-041C-42N-S3-HG2-ET-NN-D7-ES-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines the motor, power stage, and control electronics in one housing to support precise torque and speed regulation on distributed machine axes. By placing the inverter electronics at the motor, the design shortens motor power cabling and reduces the need for a separate cabinet-mounted amplifier. This arrangement suits packaging, assembly, and handling equipment where compact installation and direct mounting are useful. It can be used where several synchronized axes are spread across the machine frame and available cabinet space is limited. Its plain output shaft couples directly to gearheads or timing pulleys.

Electrical power is supplied at DC 750 V, allowing the integrated inverter to draw energy from a centralized DC bus. Heat is removed solely by natural convection, so the housing should be mounted where air can circulate freely around it. Field wiring is simplified by a hybrid connector, and fieldbus communication is handled through Multi-Ethernet for external master connectivity. The unit reports position through Hiperface feedback, and each revolution is divided into 16 signal periods by a capacitive single-turn encoder that resists magnetic contamination. This feedback data supports closed-loop control during continuous motion and indexed positioning.

An electrically released brake energized with DC 24 V supports controlled stopping when power is removed from the DC link. The drive uses frame size 041 with motor length C, and winding code 42 matches the electrical characteristics to moderate-inertia loads. A shaft seal is present to help protect the bearing area from dust or light splash in enclosed machine sections. The unit carries the Basic performance level, so any required safety monitoring must be provided by external devices. This arrangement suits machines that use separate safety hardware outside the drive.
