Product Description:
The DKS01.1-W050A-DL40-01-FW is a digital servo drive from Bosch Rexroth Indramat's DKS Intelligent Digital Servo Drives series. It regulates motor torque and speed by rectifying the plant's three-phase supply and modulating the resulting DC link for compatible servo motors. In automated assembly cells, packaging modules, and material-handling stations, the drive serves as the link between incoming electrical power and the axis control loop. This arrangement lets the controller command acceleration, holding torque, and speed changes while the drive supplies the motor with controlled current. Because the control electronics and power section are integrated in one unit, the drive can respond quickly to changing load demands on positioning axes. This is useful on axes that need repeatable starts, stops, and speed corrections during normal production cycles.
The drive operates from a nominal 3 × 230 V supply at standard industrial line frequency. Internally, it maintains a 300 V DC bus and can deliver 25 A of continuous output current, while short acceleration demands can rise to 50 A. Pulse-width modulation runs at 4 kHz, which shapes the motor current waveform and influences audible motor noise. Heat is removed through passive dissipation, and the power section produces notable thermal loss during operation. The built-in bleeder resistor absorbs regenerated energy during braking, helping stabilize the DC bus when the axis decelerates.
Above the rated ambient range, the unit can still operate up to +55 °C with reduced output. Its maximum apparent power draw is 9.5 kVA, and the enclosure has IP10 protection, so the drive should be installed inside a control cabinet. Operation is permitted at elevations up to 1000 m without derating under the stated conditions. Noise emission is standard, and storage temperatures extend well beyond normal operating conditions for transport and warehousing. These operating limits should also be considered with cabinet airflow and the heat generated by nearby equipment.
