Product Description:
The KMS02.1B-A018-P-D7-ET-ENA-NN-NN-FW is a near-motor servo drive produced by Bosch Rexroth Indramat within the KMS Electronic Drives series. Designed to mount close to the actuator, it integrates power electronics and fieldbus communication so that motion axes can be distributed along the machine frame. In an automation cell, the drive supplies regulated current to a synchronous motor while the central controller transmits setpoints over Ethernet. This layout helps place the electronics near the motor and reduces cabinet wiring across longer machine sections. By shortening motor leads, it reduces voltage-rise stress and improves electromagnetic compatibility in industrial machinery.
During steady operation, the unit provides a continuous phase current of 5.8 A @ 4 kHz, yet it can deliver up to 17.7 A @ 4 kHz for short dynamic peaks. These currents are supplied from a shared DC bus maintained at 750 V DC, and 0.02 mF of capacitance helps smooth regeneration events. Internal losses reach 50.00 W, and the aluminum housing dissipates this heat through natural convection, eliminating the need for a fan. With a mass of 2.50 kg, the drive can be mounted on moving axes without excessive inertial load. Control and diagnostic data are transmitted through a Multi-Ethernet interface that supports common industrial networks.
Position feedback is transferred through the Encoder ACUROlink channel, enabling high-resolution closed-loop control without extra wiring. A molded enclosure rated IP65 shields the electronics from dust and low-pressure water jets, making cabinet-free installation feasible beside the machine. For fault conditions, the power stage withstands a short-circuit current of 42,000 A rms, and its voltage rise is limited to 5 kV/µs to match standard motor insulation classes. The control section draws 17.5 W, and the unit is assigned a basic performance level.
