Product Description:

The DKS01.1-W030B-RL03-00 is a digital servo drive manufactured by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. This version 1 unit controls synchronous or induction servomotors in automated machinery through digital drive regulation. It applies closed-loop speed and position regulation for packaging lines, material handling stations, and other motion platforms that require repeatable motor control during automated cycles.

During operation, the drive delivers a continuous motor current of 30 A and uses an internal DC bus of 300 V, supporting stable output during sustained axis movement. Power is normally supplied through a three-phase line at 3 × 230 V AC, sustaining 15 A per phase, while a single-phase feeder can provide 10 A where only one line is available. The inverter section switches at a carrier frequency of 18 kHz to improve torque linearity and limit audible tones. Rotor position is reported to the control electronics through a resolver interface, and a 4 mA diagnostics loop sends basic status to supervisory equipment. The start-inhibit circuit draws 1.5 W, and heat is removed by conduction and convection across the housing surfaces.

Energy returned during deceleration is absorbed by an internal resistor that dissipates 0.3 kW continuously and up to 5 kW in short bursts, with waste heat handled by passive dissipation fins. Up to 3000 program blocks can be stored for complex motion sequences, and the diagnostics port also provides an analog signal of ±10 V DC that can be used for external monitoring. When a three-phase source is unavailable, the drive accepts a single-phase feed at 1 × 230 V AC without changing control behavior. The unit has an IP 10 rating, so cabinet mounting is required. Reliable function is maintained up to 1000 m elevation, and cooling relies solely on passive heat dissipation without forced airflow.
