Product Description:

The DKS01.1-W100A-DL04-00 is a digital servo drive from Bosch Rexroth Indramat in the DKS Intelligent Digital Servo Drives series. It regulates torque, speed, and position for AC servomotors in automated equipment, allowing a controller to coordinate axis motion with repeatable response during production cycles. The unit uses a DEA 4.1 binary I/O port with 15 inputs and 16 outputs for status exchange, while the DLC 1.1 command interface handles higher-level motion instructions and the DEF 1.1 channel works with the integrated DSF encoder format for position feedback. This arrangement lets the drive exchange machine signals, receive motion commands, and return encoder information through its built-in control interfaces.

The power section accepts a three-phase supply of 3 × 230 V (±10%) and rectifies it to an internal DC link of 300 V. It can provide a continuous motor phase current of 50 A, and the switching frequency of 4 kHz supports smooth control without excessive switching loss. The drive has a supply demand of 11 kVA, uses forced-air cooling, and operates in ambient temperatures from +5 °C to +45 °C. Under nominal conditions, power loss is limited to 480 W, which helps keep cabinet heat buildup manageable. This electrical arrangement suits servo axes that require responsive current control during repeated starts, stops, and speed changes.

During rapid deceleration, the internal chopper routes excess energy to a bleeder resistor that handles 0.5 kW continuously and up to 18 kW for short intervals, helping protect the DC link from overvoltage. This braking capacity is useful on axes with frequent stops or regenerated energy from moving loads. The drive can also deliver up to 100 A for brief periods, which supports short acceleration peaks when higher dynamic response is needed. Its compact dimensions of 170 × 373 × 355 mm support panel mounting where cabinet space is limited. The enclosure can be placed beside related power and control modules without taking excessive room in the cabinet.
