Product Description:

The DKS01.1-W100A-DS24-03-FW is a digital servo drive produced by Bosch Rexroth Indramat and assigned to the DKS Intelligent Digital Servo Drives series. As a closed-loop controller, it processes position data from DSF encoder feedback and modulates power to a connected servomotor for coordinated motion in automated machinery, material-handling lines, and packaging equipment. It serves as the power and control stage between the incoming supply and the motor, converting electrical input into regulated motor current. This arrangement allows the drive to respond to changing load conditions while maintaining accurate speed and position control during axis movement.

The drive uses a three-phase supply of 3 x 230 V AC and operates over an input frequency range of 50 to 60 Hz. Its rated output current is 100 A, and it switches against a DC bus of 300 V to support energy exchange between multiple axes. Torque is regulated through pulse-width modulation at 4 kHz, which balances current ripple with switching loss. Heat from the switching devices and control electronics is removed by natural heat dissipation, and the unit is intended for continuous service in ambient temperatures from +5 °C to +45 °C. Power loss under maximum load is 480 W. The noise emission is standard for this product line.

An integrated braking resistor handles regenerated energy with a continuous bleeder capacity of 0.5 kW and a short-term peak rating of 18 kW. This braking function helps limit DC-bus overvoltage during rapid deceleration or when a vertical axis returns energy to the drive. The enclosure is rated IP10, so the unit should be installed in a filtered cabinet with adequate cooling. It can operate in ambient temperatures up to +55 °C, can be stored from −30 °C to +85 °C, supports installation at altitudes up to 1000 m, and tolerates 70% relative humidity without condensation.
