Product Description:
The KMS02.1B-A018-P-D7-ET-ENA-SD-TO-FW is a near-motor servo drive manufactured by Bosch Rexroth Indramat and supplied within the KMS Electronic Drives series. As a decentralized drive, it is mounted close to the servo motor and conditions DC power, feedback, and fieldbus signals for motion axes on automated machinery. Operating in this position removes cabinet-length cable runs and allows rapid installation while the drive’s electronics regulate torque and speed in coordination with a central controller.
Thermal management relies on natural convection, so the housing must stay in free air without forced fans. A DC bus capacitance of 0.02 mF smooths link-voltage ripple when the drive receives the common DC supply, which is rated at 750 V DC. The internal power stage can deliver up to 18 A of phase current to the connected motor while a separate bypass path is able to carry 25 A during regenerative events. With an enclosure rating of IP65, the electronics tolerate dust ingress and low-pressure water jets, enabling machine-mounted installation. Version 1 hardware incorporates an ACUROlink encoder interface, Multi-Ethernet master communication, and an auxiliary Multi-Ethernet output coupling for daisy-chain layouts.
The output transistor array is specified for a dv/dt of 5.00 kV/µs, supporting fast voltage transitions that preserve current loop bandwidth. Under nominal load the supply line draws 7.3 A, and overall conversion losses manifest as 50 W of heat. Functional safety is addressed by the Safe Motion option, which allows speed-limited, safely stopped, or monitored axes without external relays. A short-circuit withstand rating of 42000 A rms coordinates with upstream protection gear and satisfies industrial fault-level requirements. Performance is categorized as Basic, aligning with the series designation 02 and the master firmware that ships with the unit.
