Product Description:

The KMS02.1B-A018-P-D7-ET-ENA-S3-NN-FW is a near-motor servo drive built by Bosch Rexroth Indramat for the KMS Electronic Drives series. Mounted directly beside the actuator, it supplies regulated three-phase power from a common DC link and keeps the motor connection path short. Its role in industrial automation is to execute precise current and velocity loops for decentralized axes, where local drive placement helps reduce cable routing complexity and supports responsive motion. This layout is suited to machines that distribute drive functions along moving sections instead of concentrating every power stage inside a central cabinet. Because the drive sits close to the load, feedback and power connections remain compact and easier to route through articulated machine sections.

At a switching frequency of 4 kHz, the drive sustains a continuous output of 5.8 A and can deliver peaks of 17.7 A during acceleration. The internal DC link is rated at 750 V DC and uses a 0.02 mF capacitor to reduce bus ripple during load changes. Rated input current is 7.3 A, and the power stage can pass as much as 25 A when regenerative energy returns from the motor. Conversion losses are 50.00 W, so the aluminum housing can rely on natural convection for cooling, and the unit is produced in Series 02 with design version 1 and Performance Level basic.

The molded enclosure is sealed to IP65, which helps protect the drive from dust and low-pressure water exposure when it is mounted near the machine axis. The assembly weighs 2.50 kg, limiting added load on moving structures and supporting direct installation beside the motor. Safe Motion monitoring is included without an SBC channel, and an output voltage rise of 5.00 kV/µs calls for shielded motor leads to protect insulation during switching events. Fault clearing capacity reaches 42,000 A rms for short-circuit conditions, while real-time position data is handled through the ACUROlink encoder interface and command traffic is exchanged over Multi-Ethernet. These communication and feedback links let the unit coordinate tightly with higher-level control networks and motor sensing hardware.
