Product Description:

The DKS01.2-W100A-DS47-52-FW digital servo drive is manufactured by Bosch Rexroth Indramat and belongs to the DKS Intelligent Digital Servo Drives series. It is a closed-loop controller that interfaces with Indramat synchronous and asynchronous servo motors, converting industrial AC power to regulated DC and high-frequency pulse outputs. Within an automation cell, the unit positions axes, regulates velocity, and supervises motor current so that machinery can perform repeatable motion profiles under varying mechanical load. The unit uses the DS47 parameter set and is version 2, with diagnostic messaging and parameter storage handled by the integrated processor.

The electrical front end accepts a three-phase supply of 3 × 230 V AC, and an internal rectifier charges a link circuit running at 300 V DC. Under rated conditions, the inverter section can deliver a continuous motor phase current of 100 A, giving it capacity for medium-power servo axes such as indexing tables or packaging lines. Current is switched through IGBTs at a modulation rate of 4 kHz, a frequency that balances thermal stress with command resolution for smooth torque production. When the axis accelerates aggressively, the converter can draw up to 11 kVA from the mains, so supply protection must be sized for this peak apparent power.

Dynamic braking energy is routed to an internal bleeder resistor that withstands regeneration surges of 18 kW, while its continuous dissipation is held to 0.5 kW. During normal operation, the electronics release up to 480 W of heat, so the unit relies on forced-air cooling and must stay below an ambient ceiling of 45 °C. The open-style housing is rated at IP10, making it suitable only for clean control cabinets where particulate ingress is limited. Installation is restricted to sites no higher than 1000 m above sea level, within humidity class F limits, and the 11 kg mass permits direct panel mounting without additional structural support.
