Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-S3-NN-FW is a near-motor servo drive developed by Bosch Rexroth Indramat for the KMS Electronic Drives series. Installed close to the servo motor, it conditions power and network signals so that motion control loops remain stable on distributed axes. Within an industrial automation cell, the unit converts shared DC-bus energy into three-phase output for the attached motor and returns regenerated power during braking. Its compact housing also supports installation on moving machine elements, which helps reduce cable length between the drive and motor.

At a 4 kHz switching frequency, the drive supplies a continuous current of 5.8 A and can deliver up to 17.7 A during short acceleration bursts. A bus link rated at 750 V DC feeds the internal 0.02 mF capacitor bank, which helps reduce voltage ripple when axis torque changes abruptly. Heat produced under nominal operation is 50.00 W, and the aluminum housing releases it through natural convection without external fans. The enclosure has an IP65 rating against dust and low-pressure water jets, allowing placement on the machine frame. The unit is design version 1 in series 02 and uses the basic performance level, which suits applications that do not require expanded diagnostic or redundancy features.

The module weighs 2.50 kg, which is useful when the drive must travel with a moving axis. It draws a rated input of 7.3 A from the intermediate circuit and provides sensor power at 12 V with a maximum encoder load of 60 mA for the integrated Hiperface feedback channel. Two probe inputs capture edge-aligned position markers, while four digital I/O points handle local interlocks and simple machine signals. High-level control is exchanged over Multi-Ethernet, so the same hardware can join PROFINET, EtherNet/IP, or EtherCAT networks. Safe Motion functions are included without SBC, and the lack of additional design options keeps the setup simple.
