Is DKR Drive Replacement Needed?
Understanding Indramat’s Legacy: The DKR Drive Controller
Indramat, once a leader in motion control solutions, ceased manufacturing operations over two decades ago following its integration into Bosch Rexroth. Despite its status as a defunct brand, many Indramat products—including the robust DKR drive controllers—are still found in active use today. Their reliability, long lifespan, and high performance have cemented their legacy in industrial motion control systems.
The DKR series drive controllers are sophisticated devices used to control the precise movement of motors, sensors, and actuators within automated systems. These units are parameterized during startup to ensure the connected motors perform application-specific tasks with precision.
Key Features of the DKR Drive Controller
-
Output Power: Ranges from 10 kW to 93 kW
-
Motor Resolution: As fine as 1/4,000,000 of a revolution
-
Internal Positioning Control: Based on motor feedback
-
Motor Compatibility: Designed for use with:
-
1MB frameless motors
-
2AD spindle motors
-
LAF and LSF linear motors
-
-
Environmental Restrictions: Not suitable for use underwater or in areas with extreme temperature fluctuations
Where Are DKR Controllers Used?
Due to their high stiffness and high-power handling, DKR drive controllers are ideal for:
-
Numerically Controlled (CNC) Machine Tools
For complex metalworking, woodworking, and high-speed drilling tasks -
Printing Press Equipment
Ensuring synchronized movement and precision in roll-to-roll systems
Should You Replace or Repair a DKR Drive?
Repair vs. Replacement
Because DKR controllers are no longer manufactured, a brand-new replacement simply doesn’t exist. While refurbished drives may be available, many issues can be resolved through cost-effective repairs. Here’s why repairs are usually the better route:
-
Legacy Support: Most DKR failures involve replaceable internal components, not total drive failure.
-
Cost Savings: Repairs are far more affordable than sourcing and integrating newer systems.
-
Reduced Downtime: Repairs often result in shorter system outages compared to full controller migration.
Always disconnect power to the control cabinet before attempting to repair or replace a DKR drive controller.
Environmental Requirements for DKR Drives
Proper ambient conditions are critical to prolonging DKR lifespan and avoiding faults:
| Condition | Specification |
|---|---|
| Operating Temp | 5 °C to 45 °C (max 55 °C) |
| Installation Altitude | Up to 1000m (max 5000m with derating) |
| Humidity | Low-moisture, non-condensing air |
Failure to maintain these conditions can result in performance loss or irreversible drive damage.
Frequently Asked Questions (FAQs)
Can I buy a new DKR drive controller?
No. DKR drives are legacy products and are no longer manufactured. Only refurbished units are available.
Is it safe to operate a DKR drive outside the specified ambient temperature?
No. Operating outside the recommended range increases the risk of overheating, drive failure, and control inaccuracies.
How long do DKR drive repairs take?
At Wake Industrial, most repairs are completed within 3–7 business days, depending on the issue and parts availability.
Final Thoughts
The DKR drive controller is a dependable and powerful legacy drive still valued across industrial sectors. Though replacements are rare, repairs are often simple and effective. With Wake Industrial’s support, your legacy Indramat systems can continue operating efficiently and reliably for years to come.
