Product Description:
The DKS01.1-W050A-DL01-01-FW drive controller is produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It mounts inside a control cabinet and acts as the regulated power stage between a CNC or PLC and a synchronous motor, supporting closed-loop motion control, diagnostic handling, and braking functions in assembly cells, conveyor zones, and other automated equipment that depends on synchronized axis response. The unit also connects to Indramat bus modules so multiple axes can share a common DC link in coordinated motion systems. This layout keeps the power electronics close to the motor control loop while leaving higher-level command logic to the machine controller.
During operation, the drive uses a three-phase supply of 230 V (3-Phase) and converts it into an internal DC link of 300 V. Under rated load, it delivers 25 A of continuous motor current through a modulation stage that switches at 4 kHz, which helps regulate motor output with stable current control. The input accepts 50–60 Hz line frequency, allowing use in different regions without changing the basic electrical arrangement. Conduction losses total 305 W, excluding the braking resistor, and heat leaves the housing through natural dissipation. The open-frame enclosure has IP10 protection for clean cabinets, the noise emission is standard, and the unit is Version 1 with diagnostic capability. That arrangement suits cabinet-mounted systems where airflow and clearance are controlled. The permitted operating range is +5 to +45 °C.
For dynamic moves, the inverter can momentarily supply 50 A of peak current, which supports short acceleration demands above the continuous rating. During deceleration, a bleeder circuit absorbs 0.35 kW continuously or up to 9.4 kW in short bursts without overstressing the DC link. This helps the drive absorb returned energy during rapid stops. At full load, the control electronics and braking network may demand 9.5 kVA from the mains. Installations are permitted at elevations up to 1000 m without derating, and ambient temperature can rise to +55 °C when output is reduced proportionally. The storage range of -30 to +85 °C helps protect the drive during shipping and warehouse storage before installation.
