Product Description:

The DKS01.1-W050A-DL01-00 is a digital servo drive produced by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. It is designed to supply regulated current to brushless servo motors while exchanging position data through a DSF resolver interface. In industrial automation systems, it forms the link between low-voltage control electronics and the mechanical axis, translating numeric motion commands into precise motor torque and velocity. This arrangement allows the control system to command acceleration, deceleration, and holding behavior with consistent electrical response from the motor.

Incoming power is three-phase at 3 × 230 V AC ±10%, and the drive draws up to 9.5 kVA at maximum load. After rectification, the internal bus is held at 300 V DC and feeds an IGBT bridge that switches at 4 kHz. Continuous current capability reaches 50 A, delivering the torque needed for medium-frame servomotors. Thermal management relies on passive heat dissipation, and the electronics release up to 305 W outside the bleeder circuit under worst-case duty. Rated values apply at ambient temperatures up to 55 °C and elevations up to 1000 m without derating. Humidity conforms to DIN 40040 class F, the power path remains three-phase, and the noise emission is standard.

The braking resistor assembly absorbs regenerative energy from decelerating axes. During short deceleration intervals, it can absorb a peak of 9.4 kW, while its continuous dissipation limit is 0.35 kW. This internal resistor helps control DC-link voltage during braking events without requiring external braking hardware. The enclosure has a rating of IP10, so the drive is finger-safe but must be installed inside a control cabinet. Passive cooling and cabinet installation should be considered when planning panel spacing and ventilation around the unit.
