Program Continuation:

Axis %1 drive %2 measuring circuit error of absolute track, code %3

%1 = NC axis number %2 = Drive number %3 = Fine error coding

Absolute encoder (EQN 1325) Monitoring of the encoder hardware and the EnDat interface

More accurate diagnostics via MD5023: $MD_ENC_ABS_DIAGNOSIS_MOTOR (diagnostics for absolute track on motor measuring system).

Bit nos. and their meaning:

Bit 0 Lighting failed

Bit 1 Signal amplitude too small

Bit 2 Code connection error

Bit 3 Overvoltage

Bit 4 Undervoltage

Bit 5 Overcurrent

Bit 6 Battery change necessary

Bit 7 CRC error (evaluate bit 13), note: see below

Bit 8 Encoder cannot be used, assignment of absolute track to incremental track not allowed

Bit 9 C/D track for ERN 1387 encoder incorrect or EQN encoder connected

Bit 10 Log cannot be aborted

Bit 11 SSI level detected in data cable

Bit 12 TIMEOUT while reading measured value

Bit 13 CRC error (evaluate bit 7), note: see below

Bit 14 (810D) Wrong IPU submodule for direct measuring system

Bit 15 Encoder defective

CRC error: CRC error bit 7 and bit 13, meaning:

Bit 7: 0, bit 13: 1 CRC error from SIDA-ASIC Bit 7:1, bit 13: 0 Control check byte error

Bit 7: 1, bit 13: 1 Error on correction of absolute track by incremental track Bits 12 and 15: Zero level monitoring SSI Bits 14 and 15: Idle level monitoring SSI

Check encoders, encoder lines and connectors between drive motor and 611D module. Check for temporary interruptions (loose contact) caused, for example, by movements in trailing cable. If necessary, replace the motor cable.

Incorrect cable type

Controller hardware not suitable for EnDat interface (e.g. control module with EPROM) Switch control OFF - ON.
