Product Description:

The DKS01.1-W050A-DL41-01-FW is a digital servo drive produced by Bosch Rexroth Indramat as part of the DKS Intelligent Digital Servo Drives series. It regulates torque, speed, and position loops for servo and induction motors used in automated assembly cells, gantries, and packaging equipment. By combining closed-loop current control with internal position evaluation, the unit supplies precise motion commands that translate directly into repeatable mechanical movement on production lines. This supports indexing, speed regulation, and position control in equipment that must respond predictably during frequent cycle changes.

The drive accepts a three-phase supply of 3 x 230 V at a line frequency of 50/60 Hz. Inside, a DC link of 300 V is switched through an IGBT bridge operating at 4 kHz. The power section can deliver a continuous motor phase current of 50 A, while digital servo feedback keeps velocity and position aligned with the commanded motion profile. Regenerated energy is routed to an internal bleeder, and passive heat dissipation removes residual heat from the power stage. The housing has an IP10 rating, so the unit is intended for cabinet installation with unobstructed airflow over the heat sink.

The energy handling stage absorbs up to 0.35 kW of regenerated power continuously, and short deceleration peaks can be shunted at 9.4 kW. Electronic losses reach 305 W at maximum load, so ambient air must remain between +5 °C and 45 °C for full output, with operation permitted up to 55 °C when current is reduced. Full performance is available at installation heights up to 1000 m above sea level, and the standard noise emission class keeps acoustic output consistent with typical industrial cabinet-mounted drives. This operating range suits controlled indoor installations where ventilation and mounting clearance are managed as part of the machine layout.
