Product Description:

The DKS01.1-W050A-RA01-02-FW servo drive is manufactured by Bosch Rexroth Indramat and is part of the DKS Intelligent Digital Servo Drives series. As a digital servo drive, it delivers regulated current and voltage to brushless servo motors so automated stations can hold position, index, or follow velocity profiles with consistent accuracy in positioning and speed-control tasks. The Version 1 unit incorporates a resolver interface, allowing the connected motor to report rotor angle without a separate feedback converter and giving the control loop the feedback needed for stable servo operation. Its passive heat dissipation keeps the housing within temperature limits while maintaining standard noise emission.

This model connects to a three-phase mains supply of 3 x 230 V ±10% at 50/60 Hz, and the line is rectified to an internal DC bus of 300 V that feeds the output stage. A rated phase current of 50 A is available for dynamic moves and acceleration events, while the continuous current is limited to 25 A during steady operation to prevent thermal overload. Pulse-width modulation is generated at 4 kHz, a switching speed that balances current ripple with semiconductor losses and keeps acoustic output in the standard range. The unit can operate up to 1000 m elevation without derating, and its enclosure under DIN 40 050 is intended for installation in a protected cabinet with unrestricted airflow.

During braking, the drive can return 0.35 kW continuously to the shared DC bus and absorb peaks up to 9.4 kW for short intervals during deceleration in cyclic motion. Internal losses reach 305 W at maximum electrical load, so cabinet ventilation must remove that heat to keep component temperatures stable. The housing has an IP10 protection level, which indicates open slots for convection and makes unobstructed airflow essential. This regeneration path supports controlled deceleration on indexing and positioning axes that share a common DC bus.
