Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-S3-TO-FW is a near-motor servo drive from Bosch Rexroth Indramat in the KMS Electronic Drives series. The device is intended to mount close to rotary or linear actuators so that cable lengths and electromagnetic losses stay low in distributed automation cells. It carries series designation 02 and design version 1. Within this basic performance level, the unit integrates Safe Motion functions without SBC and communicates with higher-level controllers through a Multi-Ethernet master link. Encoder feedback is accepted through a Hiperface interface, and an additional Multi-Ethernet output coupling is provided for daisy-chain wiring.

This drive converts a DC link of 750 V DC to three-phase motor power and supports a rated mechanical output of 2.2 kW. Electrical loading at the input is limited to 7.3 A during nominal operation, and energy is stored in a compact link capacitor rated at 0.02 mF. The housing has an IP65 protection rating, allowing installation on the machine frame without an additional cabinet, and the internal components are cooled by natural convection. Control electronics consume 17.5 W, and the total mass is 2.5 kg, which helps reduce stress on robotic arms. A DC bus voltage monitor, together with Safe Motion logic, is powered continuously from the control supply so that the unit can react to faults even when motor power is removed.

For dynamic cycles, the servo drive delivers a continuous phase current of 5.8 A. Transients may draw up to 18 A from the inverter, and fast braking can bypass an external resistor with current up to 25 A. Heat produced during these overload windows is limited by an allowable power dissipation of 50 W. The Safe Motion option lets the application maintain monitored speed or stop categories without an SBC relay, and the Multi-Ethernet architecture keeps diagnostic data synchronized with central PLCs.
