Product Description:

The DKS1.1-W100A-DA01-00 digital servo drive is produced by Bosch Rexroth Indramat and belongs to the DKS Intelligent Digital Servo Drives series. It converts fixed three-phase mains power into controlled motor currents so that automated axes follow velocity or position commands from industrial controllers. By integrating power electronics, a microprocessor, and resolver signal processing, the unit serves as the central actuator interface in packaging lines, material-handling modules, and machining centers. Its control structure supports closed-loop servo operation, allowing the connected motor to respond accurately to commanded changes in speed and position.

Under maximum load, the inverter draws an apparent power of 11 kVA and has a power loss of 480 W without the bleeder. The power section accepts a three-phase supply of 3 x 230 V AC within a ±10% tolerance and operates on line frequencies from 50 to 60 Hz. Internally, this input is rectified to a 300 V DC link that switches at 4 kHz to generate the motor output waveform. Continuous armature current is rated at 50 A, and the current regulator can reach 100 A for short acceleration periods. That switching arrangement helps the drive deliver smooth current control during changing load conditions. Position feedback is handled by a DSF resolver, while humidity tolerance follows Class F under DIN 40040 and the enclosure has IP10 protection.

The chopper section dissipates regenerated energy continuously at 0.5 kW and can absorb peaks up to 18 kW during braking. Full output is maintained up to an ambient temperature of 45 °C, with reduced output permitted up to 55 °C. Installation is allowed at elevations up to 1000 m without performance loss, and the minimum storage temperature is -30 °C. These limits describe how the drive should be applied when braking energy, ambient heat, and installation height are considered during system layout.
