R911292831
The R911292831 (DKC05.3-016-7-FW) is a high-quality Drive Controller from the Rexroth EcoDrive 03 series by Bosch Rexroth Indramat. This unit sits within version 3 of the 0.5 series and features a rated type current of 16A under voltage category 7. The device is designated primarily for servo applications, such as EcoDrive03 drives, ADF main spindle motors, 1MB frameless spindle motors, digital AC motors, and linear synchronous direct drives. It's important to note that it includes a firmware module, which requires separate ordering, and its use for applications outside of those specified could result in damage.
This controller employs Rexroth IndraDrive capacitors in its DC bus as power stores, with a built-in capacitor in the supply unit. These capacitors can maintain power even after the main power supply is stopped, necessitating discharge before interaction. The controller's discharge mechanism is integrated and can reduce voltage below 50V within a specific time. If additional capacitors are connected with the DC bus, they need to be discharged to avoid potential risks. The controller also includes a holding brake for additional safety, however, adherence to mounting and operational instructions is paramount for optimal performance and user safety.
