Technical Specifications

Note: Electrical parameters (rated torque, rated speed, encoder resolution) are not published here to prevent misapplication. Confirm your exact axis assignment and controller firmware version before ordering. Our technical team will cross-verify prior to shipment.

How Sourcing This Part Extends Asset Life by 5–10 Years

The decision to maintain a KUKA KR500 line rather than replace it is a capital allocation decision, not a maintenance decision. A KR500 cell with a functional mechanical structure, calibrated base frame, and intact wiring harness retains full production capability. The servo motor is a field-replaceable unit. Replacing it costs a fraction of one percent of the cell's original installed value.

Condition & Reliability Assurance

Every 1KR500-R2830-F 00-170-721 unit processed by DriveKNMS passes a five-stage inspection protocol before it is offered for sale:

1. Electrolytic Capacitor Assessment — Internal capacitors are tested for capacitance drift and ESR degradation. Units with capacitors outside tolerance are either recapped or rejected. Capacitor failure is the primary cause of servo drive instability in motors stored beyond five years.

2. Encoder and Feedback Integrity Check — The resolver or encoder assembly is verified for signal continuity and output accuracy. A degraded feedback signal produces axis positioning errors that are frequently misdiagnosed as controller faults.

3. Winding Resistance and Insulation Test — Phase-to-phase resistance is measured and compared against reference values. Insulation resistance is tested at rated voltage to confirm winding integrity.

4. Shaft and Bearing Inspection — Shaft runout is measured. Bearings are assessed for play and rotational noise. Units with bearing wear are relubricated or rebearinged before release.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Key Features for System Maintenance

Drop-in replacement: The 1KR500-R2830-F 00-170-721 is a direct mechanical and electrical substitute for the original installed unit. No modifications to the robot's mechanical structure, cable routing, or KRC4 controller configuration are required.

No reprogramming required: The KRC4 controller identifies the motor through the resolver feedback and the axis-specific mastering data stored in the controller. Replacing the motor and re-mastering the axis — a procedure that takes under two hours for a qualified KUKA technician — restores full operation. There is no firmware change, no safety parameter reset, and no production program modification.

Avoids engineering reconstruction costs: Integrating a replacement robot cell requires mechanical alignment, load testing, safety fence recertification, and production program re-validation. Depending on the application, this process takes 4 to 12 weeks and requires external engineering resources. A motor swap eliminates this cost entirely.
