Description
Core Product Summary
The Bosch Rexroth Indramat DKC11.1-040-7-FW is an AC servo drive controller belonging to the ECODRIVE DKC11.1 product series. It is engineered to provide precise, cost-effective motor velocity and position control for single-axis and multi-axis industrial automation systems, including packaging, assembly, and handling equipment.
Operating with a rated peak current of 40 A and a nominal DC bus connection voltage rating up to 700 V DC, this drive unit utilizes an analog speed command interface with integrated position detection capabilities. The module is designed for direct control cabinet mounting and operates with factory-configurable firmware (FWA-ECODRV) to support standardized motor-drive parameterization.

Detailed Product Overview
The Rexroth Indramat DKC11.1-040-7-FW serves as a centralized drive component within the ECODRIVE architecture, facilitating high-dynamic motion control for industrial AC servo motors. Its primary function is to interpret velocity and directional command signals from higher-level PLCs or motion controllers and supply controlled current to matched servo motors.
Equipped with an analog interface, the drive captures encoder feedback from the attached motor, delivering closed-loop speed regulation alongside precise position monitoring. Built-in diagnostic routines assist maintenance and commissioning personnel by evaluating fault status codes and operational conditions via standardized status signal outputs.
The drive controller incorporates integrated protection mechanisms against electrical contact and internal thermal overloads, maintaining drift-free standstill control during active operation through hardwired input signals.
