Product Description:

The DKS01.2-W100A-DS50-00-FW is a digital servo drive produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It conditions fixed-frequency plant power and supplies regulated current to synchronous motors, enabling precise torque, speed, and position control in automated assembly lines, packaging stations, and material-handling axes. While occupying a compact frame, the unit integrates motion logic, parameter memory, and onboard diagnostics, reducing cabinet wiring and simplifying preventive maintenance routines within industrial automation cells.

On the supply side, the drive accepts a three-phase mains supply of 3 x 230 V AC, which is rectified to a DC link of 300 V; this link is switched at a carrier of 4 kHz to synthesize the motor waveform. Regenerated energy is routed to an internal bleeder that dissipates it continuously at 0.5 kW and withstands peaks up to 18 kW, preventing overvoltage during rapid deceleration. Cooling relies on passive heat dissipation, so no forced airflow is required in standard cabinets. A 4 mA diagnostic current loop and a ±10 V DC status output connect directly to PLC inputs for fault reporting, and hardware version 2 uses optimized gating that keeps acoustic emission within the standard noise classification.

The power stage delivers a continuous motor current of 50 A, while short-term demands can rise to 100 A for acceleration bursts. Under full electrical load, the unit draws 11 kVA from the mains and converts up to 480 W of that energy into heat, which must be conducted away by the mounting plate. The housing meets the IP10 protection class, so live parts remain guarded but the unit must be installed inside a closed panel. Reliable operation is permitted up to 1000 m elevation, and the humidity class is F. Passive cooling and monitored bleeder temperature help manage thermal load during continuous service.
