Product Description:

The DKS01.1-W030B-DA01-00 is a digital servo drive from Bosch Rexroth Indramat and belongs to the DKS Intelligent Digital Servo Drives series. Designed as the central power stage between a motion controller and a permanent-magnet servo motor, the unit regulates current and voltage so that commanded torque and speed profiles are met in automated machinery, packaging lines, and material-handling axes. Its integrated resolver interface supplies position feedback for closed-loop commutation and supports accurate motor control during changing load conditions.

At nominal load, the drive delivers a continuous output of 30 A, giving headroom for medium-frame motors that draw high acceleration currents. Power is supplied from a common DC link at 300 V DC, allowing energy exchange among drives on the same bus. The rectifier accepts mains in the 50–60 Hz range, so regional line frequency differences do not require hardware changes. Motor voltage is synthesized with a carrier frequency of 18 kHz, a switching rate that limits audible noise while keeping transistor losses under control. For cabinet integration, the housing is rated IP10, which provides basic finger protection but requires an enclosed panel for dust and fluid protection.

In dynamic cycles, the internal bleeder resistor dissipates regenerative energy; its continuous capability is 0.3 kW, while short bursts up to 5 kW help prevent overvoltage during rapid deceleration. The drive maintains full electrical performance up to 1000 m above sea level, after which current derating offsets lower air density and reduced cooling efficiency. Ambient operation without derating is permitted up to +45 °C, and operation above that temperature requires reduced output current. The unit uses standard cooling and has reduced noise emission for installation in densely packed automation cabinets.
