Product Description:
The DKS01.1-W100A-DL05-00 is a servo drive manufactured by Bosch Rexroth Indramat and assigned to the DKS Intelligent Digital Servo Drives series. It functions as the power interface between a motion controller and a motor, converting commanded set points into regulated current and voltage so that automated machinery can hold position, accelerate, or decelerate with closed-loop precision. This arrangement allows the drive to support repeatable motion on production equipment where stable torque control and responsive speed changes are required. It is suited to servo applications that require coordinated movement, quick response to command changes, and controlled braking behavior.
Electrical input is a three-phase supply at 3x 230 V AC (±10%), permitting connection to common factory mains. Internally, the converter maintains a regulated 300 V DC bus that feeds an IGBT bridge that switches at 4 kHz, which helps limit motor current ripple during operation. The drive accepts line frequencies from 50 Hz to 60 Hz, covering both major power grids without retuning. Continuous operation allows phase currents up to 100 A, and regenerated energy is routed to an integrated bleeder with a continuous absorption capability of 0.5 kW. Thermal energy produced by the power stage is removed through dedicated heat dissipation hardware, and conversion losses can reach 480 W under heavy load.
During rapid braking, the resistor handles peaks up to 18 kW, which helps keep the DC link voltage within safe limits during deceleration. When the inverter and auxiliaries operate at full capacity, the installation must provide up to 50 kVA, a value used for transformer and feed cable sizing. Reliable service is maintained at ambient temperatures as high as +55 °C, and operation beyond this point requires external cooling or power derating. Noise emission remains at a standard industrial level, and cooling is done by heat dissipation. Diagnostics, fieldbus processing, and protective shutdown logic are handled by the control electronics.
