Product Description:

The DKS01.1-W100A-RA02-00 servo drive is produced by Bosch Rexroth Indramat as part of the DKS Intelligent Digital Servo Drives series. This DKS01.1-W100A-RA02-00 unit is a digital servo drive intended to regulate synchronous motors in automated machinery. It connects to a three-phase supply with a nominal input of 230 V AC and operates on an internal 300 V DC bus derived from that line power. Version 1 hardware combines resolver feedback with the DAA 1.1 command interface so motion commands, status words, and diagnostics pass between the drive and its higher-level controller.

During steady motion, the drive delivers a continuous output of 50 A, while short acceleration bursts can draw a 100 A peak. These current limits set the thermal load for cables and enclosure airflow. The internal link maintains 300 V on the DC bus, which helps the drive support consistent torque production during operation. When the mechanical load reverses, regenerated energy is dissipated by a bleeder circuit that can absorb 18 kW momentarily, preventing bus overvoltage trips. At maximum demand, the input side can require 11 kVA from the plant distribution network, so upstream breakers and wiring must be sized accordingly. Continuous operation produces 480 W of power loss, so that heat must be removed from the cabinet during installation.

Control resolution is enhanced by a PWM carrier of 4 kHz, and axis position is forwarded to the PLC through Absolute SSI signals. The housing meets IP10, so it must be mounted inside a protected cabinet. Average regenerative heat is limited to 0.5 kW, which matches the continuous bleeder capability and helps keep internal temperature rise under control. This combination of feedback handling and enclosure protection suits cabinet-mounted motion systems that need absolute position transfer without exposing the electronics to open machine areas.
