Product Description:

The KSM02.1B-041C-42N-M1-HP2-ET-L3-D7-TO-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It combines a permanent-magnet motor and an embedded inverter in one housing, so power conversion, motion control, and feedback handling take place in a single body. The unit uses motor size 041 and length code C to fit compact machinery layouts, and it is built for basic performance in general automation tasks such as pick-and-place stations and format adjustment axes. This arrangement also reduces the need for separate cabinet-mounted amplifier hardware on decentralized axes.

The drive operates from a DC 750 V intermediate circuit, which supports shared buses without requiring large conductors. Heat from the electronics is removed by natural convection, so no fan or liquid cooling loop is needed. A single Hybrid Connector carries DC power, Ethernet communication, and feedback signals, which helps keep cable routing compact. Position data are provided through a Hiperface optical encoder with multi-turn absolute capability, and functional shutdown is handled by the Safe Torque Off (STO) channel. Winding code 42 identifies the electrical layout, a shaft seal helps block oil splash, and the unit is design version 1.

For load holding, the brake is electrically released, so it clamps the rotor when supply voltage is absent and releases at DC 24 V. Real-time control and diagnostics are exchanged over the Multi-Ethernet interface, allowing the drive to communicate on supported industrial Ethernet networks. The optical sensor provides 128 signal periods per revolution, which the drive can interpolate for finer position feedback during motion control. A shaft with a keyway transmits torque, and the sealed housing helps limit contamination in compact multi-axis installations.
