Product Description:

The KMS02.1B-A018-N-D7-ET-ENH-ST-ST-FW is a near-motor servo drive manufactured by Bosch Rexroth Indramat as part of the KMS Electronic Drives series. As a decentralized drive module, it mounts directly on the machine frame, shortening motor cables and easing control cabinet wiring in automated cells. The device carries the 02 series designation and design version 1, giving motion axes a compact drive solution with current regulation placed close to the actuator. This layout supports distributed machine architectures where cabinet space is limited and local installation is preferred.

Its continuous output capability is 5.8 A, which is the sustained current the drive can deliver without thermal derating. For rapid acceleration or peak load events, the current ceiling increases to 18 A. The internal DC link is stabilized at 750 V DC, and a 0.02 mF bus capacitor smooths voltage ripple in the circuit. On the supply side, the module draws a rated input of 7.3 A. Heat generated by switching and control electronics is limited to 50.00 W, while natural convection cooling helps manage internal temperature. Phase insulation tolerates slew rates of 5.00 kV/µs to ground and between phases, which reduces stress on connected motor cabling.

Feedback is processed through a Hiperface encoder interface, and command data are exchanged via a Multi-Ethernet master port that supports common industrial protocols. The performance level is Basic, which suits general-purpose machinery that uses standard motion and communication functions. In the event of a supply fault, the power stage can withstand a prospective short-circuit current of 42,000 A RMS, which supports coordination with upstream protective devices. This interface combination allows the drive to support closed-loop motion control in distributed automation equipment with local drive placement near the motor.
