Product Description:

The DKS01.1-W100A-DS54-00-FW is a digital servo drive manufactured by Bosch Rexroth Indramat for the DKS Intelligent Digital Servo Drives series. Within an automation cell, it regulates torque, speed, and position of three-phase servo motors while exchanging commands and feedback over a fiber-optic SERCOS interface for coordinated motion with the machine controller. The internal bleeder resistor, power electronics, and microprocessor control are combined in one housing, making the unit a compact axis amplifier for industrial robots, packaging lines, and material-handling equipment.

The drive’s energy-dump circuit can dissipate 0.5 kW continuously and absorb surges up to 18 kW during rapid deceleration, which helps prevent DC-bus overvoltage. Its intermediate circuit operates on 300 V nominal DC derived from a three-phase supply. Current capability is matched to medium-power servomotors, with a rated output of 100 A and short-term overload capacity for brief load spikes. Pulse-width modulation is clocked at 4 kHz, a switching speed that balances acoustic noise with smooth motor operation. Heat generated by semiconductor switching is removed by passive dissipation through the housing fins, so the unit does not require forced airflow. Electrical hookup is three-phase, and communication relies on the SERCOS optical ring, which helps keep cabinet wiring orderly.

For system design, the maximum apparent power drawn from the mains is 11 kVA, so upstream circuit breakers and cables can be selected to match the load. The enclosure carries a protection rating of IP 10, which provides finger-safe access but no water sealing, so the drive must be installed inside a control cabinet. Reliable operation is specified up to 55 °C ambient and elevations of 1000 m without derating, and the standard noise emission is suitable for factory environments.
