Product Parameters

• Manufacturer / Brand: Indramat (Bosch Rexroth).
• Series: KDS (Digital Servo Drive).
• Current Rating: 150A continuous current output.
• Peak Current: 300A, as denoted in the model number, for handling high dynamic overloads.
• Supply Voltage: Typically designed for a standard 3-phase AC line voltage (e.g., 380-480V AC).
• Control Technology: Digital signal processor (DSP) based control for precise regulation of torque, speed, and position.
• Communication Interfaces: Equipped with standard interfaces such as SERCOS (Serial Real-Time Communication System) or, for later models, Profibus/Profinet for seamless integration into higher-level PLC controls.
• Protection Class: IP20 for installation in protected control cabinets.
• Cooling Method: Typically forced air cooling via an integrated fan.

Advantages and Features

• High Dynamic Response: The high peak current (300A) enables extremely fast acceleration and deceleration of servo motors, minimizing cycle times.
• Digital Precision: Advanced DSP control ensures excellent setpoint following accuracy, low speed ripple, and stable control behavior across the entire speed range.
• Modular Design: Allows for flexible system configuration when combined with compatible Indramat power supply and control modules.
• Comprehensive Diagnostics: Integrated monitoring and diagnostic functions for parameters like current, temperature, and error states, facilitating quick troubleshooting.
• Proven SERCOS Integration: Native support for the high-speed, deterministic SERCOS motion bus ensures synchronized multi-axis control with minimal jitter.

Application Cases in Industry

• Packaging Machinery: Drives high-speed pick-and-place units, rotary fillers, and cartoning machines where precision timing is essential.
• Printing Presses: Controls the registration and tension of web-fed systems, requiring exceptional speed synchronization between multiple axes.
• Machine Tools: Used for controlling main spindles or high-power feed axes in milling and turning centers that demand high torque at low speeds.
• Plastics Processing: Drives the injection units and screw axes in injection molding machines, where precise pressure and speed profiles are critical for part quality.
• Automated Test Stands: Provides the dynamic muscle for high-cycle fatigue testing or dynamic simulation equipment.

Comparison with Competing Products

Compared to standard variable frequency drives (VFDs) from brands like Siemens (SINAMICS) or Allen-Bradley (PowerFlex), the INDRAMAT KDS1.3-150-300-W1 is a dedicated, high-end digital servo drive. Its primary competitors are other high-performance servo drives like the Siemens SINAMICS S120 or the B&R ACOPOSmulti. The KDS1.3-150-300-W1 differentiates itself with its exceptional power density (high current in a compact package) and its heritage in the real-time SERCOS ecosystem, which is often preferred in complex motion applications. While newer drives offer more modern fieldbus options like EtherCAT, the Indramat platform is renowned for its robustness and performance in established, high-duty-cycle installations.

Selection Suggestions and Precautions

• Selection Suggestions:
  1. Select the INDRAMAT KDS1.3-150-300-W1 when your application requires high peak torque, very dynamic motion profiles, and integration into an existing or planned SERCOS-based motion network.
  2. Ensure the connected servo motor’s continuous and peak current ratings are correctly matched to the drive’s 150A/300A specifications.
  3. Verify compatibility with the required system components, including the control module (e.g., RDC), power supply module, and feedback system.
• Precautions:
  1. Obsolescence Note: As an Indramat product, some versions may be in a legacy or discontinued phase. Secure a reliable source for spares and ensure access to service support.
  2. Expert Configuration: Parameterization and commissioning require specialized software (e.g., IndraWorks) and expertise in servo drive tuning. Incorrect settings can lead to poor performance or motor damage.
  3. Cooling and Clearance: The drive generates significant heat. Strictly adhere to specified installation clearances and ensure adequate airflow within the control cabinet to prevent thermal overload.
  4. Electrical Safety: Installation and maintenance must be performed by qualified personnel following local electrical codes. The DC bus terminals retain a hazardous voltage even after the AC supply is disconnected.
  5. System Compatibility: Do not attempt to use the drive with non-compatible or non-validated servo motors, as this can void safety certifications and lead to unpredictable operation.
