Product Description:

The DKS01.1-W100A-DL05 is a digital servo drive produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It serves as the interface between the supply network and a synchronous motor, modulating current and voltage to support precise speed and torque regulation in automated machinery and axis control applications. This Version 1 unit is intended for cabinet installation where IP 10 protection is acceptable, so it is suited to installations that provide enclosure-based protection from the surrounding environment.

Incoming power is a three-phase supply at 3 x 230 V AC, and the converter draws up to 28 A during dynamic demand peaks while its continuous rated output current is 100 A. Internally, energy is transferred to a link circuit that holds 300 V DC, and excess regenerative energy is routed to a bleeder resistor that can dissipate 0.5 kW continuously to help prevent DC-bus overvoltage during cyclical braking. Heat from the power stage is removed through passive dissipation, so cabinet airflow must be maintained. The drive accepts DSF resolver motor feedback for position control, while the Bb relay contact carries 1 A for external interlocks. An isolated diagnostics port also sources 4 mA for status circuits.

During short braking spikes, the bleeder can accept up to 18 kW for a few seconds, while overall thermal losses are limited to 480 W at maximum electrical loading. The integrated service connector supplies 10 V DC reference voltage for control-circuit measurements. Bosch Rexroth rates the unit for operation up to 1000 m above sea level and assigns it to humidity class F, so condensation should be avoided during use. The drive has standard noise emission, and screened motor cables help maintain clean operation near sensitive measurement equipment.
