Product Description:

The DKS01.1-W100A-DL02-01-FW is manufactured by Bosch Rexroth Indramat and belongs to the DKS Intelligent Digital Servo Drives series. It acts as the power and control interface between a motion controller and an AC servomotor, providing closed-loop regulation for position and speed tasks in automated lines. The drive is supplied as Version 1 hardware, has IP10 panel-mount construction, and uses passive heat dissipation to remove internally generated heat. In machine automation, this arrangement lets the controller send command values while the drive regulates motor current and corrects changes in load during motion.

The converter draws a nominal motor output current of 100 A while accepting a supply of 3× 230 V AC (±10%) at 50/60 Hz. Inside the unit, power is rectified onto a 300 V DC bus that feeds the output stage, and switching takes place at a carrier frequency of 4 kHz to shape the motor voltage waveform. Under full load, the device consumes 11 kVA, and its heat losses are removed by natural convection across the housing. Rated operation is supported up to 45 °C, while controlled derating allows continued operation at ambient temperatures up to 55 °C. This operating range suits cabinet installations that rely on normal airflow around the housing instead of dedicated cooling hardware. Noise emission is standard for shop floor environments, and the recommended installation altitude without derating is 1000 m.

An integral braking resistor limits regenerated energy during deceleration. It can dissipate peaks of 18 kW while its continuous thermal capacity is 0.5 kW. If several axes brake at the same time, the upstream supply must deliver as much as 50 kVA. The internal bleeder and bus design keep the DC link stable so the PWM stage can absorb returned energy without an external chopper. This approach helps prevent DC-bus overvoltage during short braking events and supports repeatable stop profiles in cyclic motion.
