Product Description:
The DKS01.2-W100A-D is a digital servo drive manufactured by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It operates as a closed-loop motion controller that receives command signals from a higher-level PLC. The drive then modulates motor phase voltage to manage speed, torque, and position in automated machinery and handling equipment. This control method helps the axis respond to changing load conditions without losing command accuracy during repeated motion cycles.
This drive connects to a three-phase mains supply of 3x 230 V AC and regulates motor current through IGBT switching at a pulse-width-modulation frequency of 4 kHz. The drive has a rated current of 100 A for intermittent duty and a continuous current capability of 50 A. Internally, energy is stored on a 300 V DC bus, and excess kinetic energy is dissipated by an integrated bleeder resistor that handles 0.5 kW continuously and up to 18 kW during braking peaks. Under maximum electrical loading, the unit requires 11 kVA from the supply and releases 480 W of thermal power, which is removed by passive heat-dissipation panels mounted on the housing.
The unit is intended for industrial cabinets that limit airborne moisture to Class F, and the enclosure protection is IP10. Operation without derating is permitted up to 1000 m elevation, while the maximum cabinet temperature can rise to 55 °C if current and power limits are reduced proportionally. Standard noise emission means the acoustic output follows levels typical of fanless convection-cooled drives in enclosed panels. Version 2 supports adaptive current loops that help maintain stability when line voltage fluctuates, which supports consistent servo behavior during normal industrial power variation.
