Product Description:

The DKS01.2-W100A-DS45-01-FW is a digital servo drive produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It is designed for closed-loop motion control and interfaces with Indramat servo motors and actuators in automated assembly lines, packaging equipment, and material-handling stations. The unit modulates a pulse-width-controlled output in response to encoder data so motor torque and velocity follow programmed setpoints with high repeatability. This allows the drive to support positioning and speed-regulated tasks where stable response and accurate feedback are required.

The drive operates from a three-phase supply of 3 × 230 V AC, and this input is rectified to a stabilized DC bus of 300 V for the inverter stage. It delivers a continuous output of 50 A, and its gate logic switches at 4 kHz to shape sinusoidal motor currents while helping limit audible noise. Dynamic braking energy is absorbed by an internal resistor that dissipates 0.5 kW continuously and up to 18 kW during short deceleration peaks, which helps protect the bus from overvoltage during rapid stopping. The drive uses heat dissipation for cooling, total power loss is 480 W under nominal loading, and digital servo feedback from the motor connector closes the current, velocity, and position loops without auxiliary transducers.

The drive has a peak current capacity of 100 A, allowing short bursts of torque for acceleration before electronic current reduction engages. When loaded to its maximum rating, it requires up to 11 kVA from the mains, so the supply circuit and cabling must be sized for that demand. The housing carries an IP10 rating, which means the unit is intended for installation inside a ventilated control cabinet, and operation is permitted up to 1000 m above sea level. The drive also has standard noise emission, keeping operating sound within typical industrial expectations.
