Product Description:
The DKS01.2-W100A-RL01-01-FW digital servo drive is produced by Bosch Rexroth Indramat within the DKS Intelligent Digital Servo Drives series. It acts as the power and regulation stage between the mains supply and a servomotor, using resolver feedback to control torque, speed, and position in a closed-loop axis. In automated machinery, it converts incoming electrical power into regulated motor current so commanded motion can be carried out with stable response. This arrangement lets the axis respond to command changes during acceleration, positioning, and speed regulation.
The power section accepts a three-phase supply of 3 x 230 V AC (±10%) at 50–60 Hz. Inside the drive, this input is rectified to a stabilized bus of 300 V DC, which feeds an output bridge rated for a continuous motor current of 100 A. A pulse-width modulation frequency of 4 kHz shapes the phase currents while keeping switching losses within the maximum power loss limit of 480 W. Operation is permitted from +5 °C to +45 °C, and the IP10 enclosure means the unit should be installed inside a control cabinet to reduce accidental contact with internal parts. The drive has standard noise emission for typical factory environments. Cooling depends on forced-air extraction through the cabinet, so the enclosure must provide adequate airflow at rated load.
For energy returned from decelerating axes, an internal bleeder resistor can absorb 0.5 kW continuously and up to 18 kW in short peaks, which helps prevent bus overvoltage without external dumping hardware. Motion sequences are coordinated by the DLC 1.1 command card, which handles the drive's command processing. Extended I/O and diagnostic channels are provided through the U2 auxiliary slot with the DEA 4.1 module. This arrangement supports additional signal exchange and status access during operation. Storage from −30 °C to +85 °C is permitted when the drive is not operating.
