Product Description:

The DKS01.1-W100A-DL01-00 is a digital servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. This stand-alone module accepts encoder data through a DSF feedback interface and modulates its output bridge to match commanded torque, speed, or position setpoints. In an automation cell, the drive supplies controlled three-phase power to permanent-magnet servomotors, supervises braking energy through an internal bleeder circuit, and links to higher-level motion controllers to coordinate synchronized axes on packaging, printing, or assembly equipment.

During operation, the drive draws a three-phase supply of 3 × 230 VAC with a tolerance of ±10% at line frequencies of 50–60 Hz. With its output stage rated for 100 A of continuous current, it can power medium-inertia servomotors without exceeding its normal operating range. Internally, the rectifier charges a DC bus to 300 V, and this stabilized link voltage feeds a four-quadrant inverter that produces pulse-width-modulated phase currents. When the application accelerates large loads, the converter may demand up to 11 kVA from the mains, so supply cabling and circuit protection must be sized accordingly. Humidity class F permits operation in workshops where relative humidity is moderate, provided no condensation occurs.

The built-in bleeder resistor dissipates up to 18 kW of regenerative energy in short bursts, while its continuous rating is 0.5 kW to help prevent DC-bus overvoltage during rapid deceleration cycles. Switching events occur at a carrier frequency of 4 kHz, which balances acoustic noise with motor winding losses. Component heat leaves the housing through passive heat dissipation, allowing the unit to maintain full performance up to a maximum operating temperature of +45 °C. Between this threshold and the derating limit of 55 °C, output current must be reduced. The housing carries an IP10 protection rating, so the drive must be mounted inside a control cabinet and kept below 1000 m elevation to maintain proper airflow around the fins.
