Product Description:

Bosch Rexroth Indramat’s DKS01.1-W030B-DA01-01-FW belongs to the DKS Intelligent Digital Servo Drives series and is used to regulate synchronous or induction motors in automated machinery. As a digital drive controller, it receives motion commands from a PLC, converts them into pulse width modulated output, and returns status data for closed-loop control. The unit also includes an internal bleeder resistor and thermal monitoring, which allow regenerated energy to be absorbed during rapid deceleration without requiring external braking components. This arrangement supports stable operation in systems that need controlled speed, torque, and stopping behavior.

The drive accepts a supply of 230 VAC (±10%) and supports single-phase and three-phase operation, which allows it to fit panels with different incoming mains arrangements. Internally, the input is rectified to a 300 V DC bus so the control section has a stable link voltage for motor regulation. A carrier frequency of 18 kHz modulates the IGBTs, which helps reduce audible motor noise and keeps current delivery smooth. The power section is rated for a continuous output current of 30 A, allowing the drive to operate medium-frame servo motors without immediate thermal derating.

During braking, the internal resistor dissipates 0.3 kW continuously and up to 5 kW in short bursts, which helps prevent DC-bus overvoltage when high-inertia loads stop abruptly. The enclosure has an IP10 rating, so the drive should be mounted inside a cabinet, and heat is removed through passive dissipation rather than forced airflow. Reliable operation is permitted at ambient temperatures up to +55 °C, and full output remains available up to 1000 m above sea level before derating is required. At maximum load, total input demand is 4.5 kVA, which helps with sizing the upstream supply and protective devices.
