Error Codes For Encoders With Endat Interface - HEIDENHAIN iTNC 530 HSCI Service Manual

19.3 Error codes for encoders with EnDat interface

In the event of a disturbance, the error message EnDat defective <error code> <axis> will appear.
The error code is shown in hexadecimal notation. Error codes may also appear combined, in which
case they are added together.
There are two different types of errors:

EnDat could not be read.
Possible causes:
Encoder defective
Check the wiring (cable and EnDat amplifier)
Encoder not connected
Encoder connected to wrong connector
Motor and position encoder switched
Check cable lengths
Meaning
Delete the alarm bit
Read the alarm status
Read the number of pulses
Read the number of signal periods
Read the number of differentiable revolutions
Read the measuring steps
Read the serial number
Read the type of encoder
