Product Description:

The DKS01.1-W050A-DS56-00-FW is a digital servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It works as a closed-loop amplifier that feeds regulated power to synchronous servomotors so motion controllers can execute precise position, speed, and torque commands in automated machinery. The unit is intended for multi-axis control cabinets where compact drives coordinate pick-and-place systems, packaging equipment, and material-handling stations. Closed-loop operation helps the connected motor respond accurately to command changes and load variation during repeated motion cycles.

This drive connects to a three-phase mains supply and accepts 3x 230 V AC within a ±10% window. Under continuous duty, it carries an apparent power of 25 kVA, while the output stage is rated for 50 A of load current. Power devices switch at 4 kHz to smooth motor current and keep acoustic output within the standard category. Regenerative energy is routed to an internal bleeder that dissipates 0.35 kW continuously, and cabinet airflow removes the resulting heat. The drive has an IP10 protection class for enclosed-panel installation, and the unit is version 1.

The DC link is stabilized at 300 V DC, which supports predictable bus behavior during acceleration and braking. During rapid deceleration, the bleeder can momentarily absorb 9.4 kW, while total electronic power loss reaches 305 W at full device load. These heat sources should be considered when sizing cabinet ventilation so internal temperatures remain within the allowed operating range. Reliable operation is permitted up to +55 °C ambient temperature and at elevations up to 1000 m without derating. This installation range suits equipment mounted in standard factory cabinets as well as elevated conveyor structures where ambient heat and limited airflow can affect drive temperature.
