Number Cause Check and action
17: EBI encoder low battery Battery in battery module weak Replace the battery; reference is not deleted by
the event
18: EBI encoder battery empty Battery in battery module empty Replace the battery
Initial connection –
Connection error Check the connection and correct it if necessary
Defective encoder cable Check the cable and replace it if necessary
Faulty battery module Check the battery module and replace it if
necessary
20: Resolver carrier
–
22: Resolver overvoltage
Defective encoder cable Check the cable and replace it if necessary
Incompatible encoder Compare the specification of the encoder with
the corresponding specifications from STOBER
and replace the encoder or motor if necessary;
fault cannot be acknowledged
24: Resolver failure Defective encoder cable Check the cable and replace it if necessary
48: X4 zero pulse missing Defective encoder cable Check the cable and replace it if necessary
Connection error Check the connection and correct it if
necessary
Late zero toe Check number of encoder increments per
rotation and correct it if necessary (H02)
49: X4 zero pulse distance too
small
Defective encoder cable Check the cable and replace it if necessary
Connection error Check the connection and correct it if necessary
Early zero track Check number of encoder increments per
rotation and correct it if necessary (H02)
60: Hiperface synchronisation – 63:
Hiperface link
Defective encoder cable Check the cable and replace it if necessary
Connection error Check the connection and correct it if
necessary
Electromagnetic interference Take EMC recommendations into account
[}78] and, if necessary, increase the fault
tolerance (I298)
