Encoder 2: Absolute encoder EnDat, internal fault/error

Siemens · DAsl Diagnostics and Alarms

What does 232111 mean?

The EnDat encoder's internal fault word has set fault bits, indicating a problem with the encoder's internal operation. This could relate to the lighting system, signal amplitude, position value accuracy, or issues with the encoder's power supply (over/undervoltage, overcurrent). The exact fault is detailed in r0949, where each bit represents a specific cause, ranging from a failed lighting system to encoder power supply issues.

Complete Troubleshooting Guide

  1. 1

    Check the encoder's lighting system if bit 0 in r0949 is set.

  2. 2

    Verify the signal amplitude if bit 1 in r0949 is set, and confirm the position value's integrity if bit 2 is set.

  3. 3

    Examine the encoder's power supply for overvoltage, undervoltage, or overcurrent conditions if bits 3, 4, or 5 in r0949 are set.

  4. 4

    If bit 6 is set, the encoder battery must be changed.

  5. 5

    Consider replacing the encoder or encoder cable if multiple internal errors persist.
