Product Description:

The DKS01.1-W100A-DL04-01-FW belongs to the DKS Intelligent Digital Servo Drives series manufactured by Bosch Rexroth Indramat. It is intended to regulate torque, velocity, and position of MDD synchronous motors in automated machinery where compact control electronics and integrated motion functions are required. This lets the unit serve as the power and control stage for coordinated axis motion in equipment that depends on accurate closed-loop motor control. Feedback is processed from a DSF resolver, and square-wave position signals are available for downstream controllers that require position data.

This drive is supplied from a three-phase input of 3x 230 V AC and converts that supply to a regulated DC link held at 300 V. The regulated DC link gives the internal power section a stable bus for controlled motor output. During operation, it can deliver a continuous motor phase current of 100 A, while the upstream mains must support a maximum apparent power demand of 11 kVA. That current capacity supports applications that need strong acceleration or sustained torque without overloading the drive stage. Pulse-width modulation operates at 4 kHz to limit current ripple and acoustic noise, and heat from internal losses is removed through passive dissipation rather than forced airflow.

An integrated bleeder network absorbs regenerated energy with a continuous rating of 0.5 kW and a peak capacity of 18 kW, helping prevent DC-bus overvoltage during rapid deceleration. Command and diagnostic wiring uses a local interface with 15 Inputs / 16 Outputs, which supports signal exchange with connected control hardware. The housing has an IP10 protection rating, so the drive must be mounted in a closed electrical cabinet rather than in an open installation. The unit weighs 11 kg and can operate at elevations up to 1000 m. Closed-cabinet mounting also helps preserve the intended heat path during normal operation.
