KUKA 00-246-872 SSP RDC Board Resolver Digital Converter KRC4

KUKA 00-246-872 SSP RDC Board — Resolver Digital Converter for KRC4

The KUKA 00-246-872 is the SSP RDC board (Resolver Digital Converter) used in KUKA KRC4 robot controllers. It converts the analog resolver (sin/cos) feedback from the robot's axis motors into digital position data for the controller, keeping closed-loop position control accurate. When the RDC fails, the affected axes lose position feedback — we supply a genuine replacement and confirm fitment to your specific KRC4 cabinet before you order.

Specifications

Voltage, connector layout, and board dimensions are confirmed against your KRC4 cabinet version before shipment. Send your controller type and axis configuration with your inquiry so we match the exact variant.

Industrial Applications

• Position-feedback conversion in KUKA KRC4 robot controllers across welding, handling, palletizing, and machining cells.
• Multi-axis resolver signal processing for articulated robots running KRC4, KRC4 compact, or KRC4 smallsize cabinets.
• Restoring the feedback loop when an RDC board fails, bringing affected axes back to accurate closed-loop control.

Design Purpose

The RDC board sits between the axis-motor resolvers and the controller's motion calculation. Its job is to turn the analog resolver signal (sine/cosine) from each motor into clean digital position data the controller uses to command and correct axis motion. A healthy RDC keeps every axis referenced correctly; a degraded one breaks that loop. This board is the genuine KUKA spare that restores that conversion path in a KRC4 system.

Common Failure Modes

• Loss of resolver signal on one or more axes — controller alarms for the RDC or resolver feedback.
• Axis position drift or inability to complete homing / referencing after a fault.
• Intermittent position errors that appear under load or after warm-up.
• Communication loss between the RDC stage and the controller's servo evaluation.
