Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-L3-TO-FW is a near-motor servo drive produced by Bosch Rexroth Indramat for the KMS Electronic Drives series. The unit is design version 1 in series 02 and mounts close to asynchronous or synchronous motors to reduce cable lengths and improve decoupling. In factory automation, it converts shared DC bus energy into a controlled three-phase output while maintaining feedback integrity through its integrated Hiperface encoder interface. This near-motor layout helps reduce cabinet wiring and supports compact machine sections where distributed axes are mounted directly on the equipment.

Rated for a continuous phase current of 5.8 A, the drive can sustain normal motion tasks without thermal derating, and it can reach a peak of 18 A during brief acceleration or regenerative events. The inverter draws energy from a 750 V DC bus and can deliver up to 2.2 kW of mechanical power at the motor shaft. A housing sealed to IP65 blocks dust and low-pressure water jets, which allows on-machine installation near the driven axis. The unit includes Safe Torque Off for functional safety, and a daisy-chain connection topology lets it share DC power and communication with adjacent KMS units.

Heat generated by the electronics is removed by natural convection, so no fan noise or filter maintenance is introduced when the drive is mounted inside the machine envelope. Control data travel through a master interface that supports Multi-Ethernet protocols, and an optional output coupling can pass the signal to downstream axes. Motor, encoder, and auxiliary supplies are consolidated in a hybrid cable, which reduces wiring bulk when several converters are installed in a row. The assembly weighs 3.200 kg, which helps limit added mass on moving subframes while keeping the drive suitable for compact distributed mounting.
