Product Description:

The DKS01.1-W100A-DL08-01-FW is a digital servo drive manufactured by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It interfaces with motion controllers to regulate armature current, commutation, and velocity feedback for brushless servo motors used in automated assembly cells and conveyor zones. By combining drive intelligence with fieldbus signaling, the unit removes the need for separate amplifiers and stores operating parameters directly in the drive, which helps simplify cabinet wiring.

The drive is supplied from a three-phase mains source of 3 × 230 V AC; under rated load it draws 28 A while delivering up to 100 A of phase current to the motor windings. Its incoming section can demand 50 kVA during dynamic acceleration, and pulse-width modulation at 4 kHz shapes the output to help reduce torque ripple. Analog monitor ports provide 10 V DC velocity feedback and 4 mA status current for controller monitoring. A bleeder network dissipates regenerative energy with 0.5 kW of continuous capacity, and heat is removed by conduction-based cooling while residual internal losses total 480 W. A Bb safety contact rated at 24 V DC and 1 A signals the drive-ready state to interlock circuits.

The internal DC link is stabilized at 300 V, and if bus voltage rises rapidly during braking, the resistor bank can absorb surges up to 18 kW without triggering overvoltage trips. Input protection opens when the link falls below the 200 V DC low-bus threshold, which helps prevent undervoltage jogging. Reliable operation is permitted at ambient temperatures up to +55 °C, and the IP 10 enclosure rating indicates that the unit is intended for open-frame installation inside a sealed cabinet. Mechanical relays on the Bb channel support emergency stop circuits, and the standard acoustic output suits shared control enclosures.
