Display Description Fault cause and solution
conn Serial Com. Established Position values are being transferred to the encoder,
encoder and serial interface are working.
EncId Unknown encoder ID Encoder is an unknown type and does not support the
required serial communication protocol. Encoder is the
wrong type, i.e. EnDat connected to a HIPERFACE
feedback card. Solution: verify encoder type.
bdCbi Cable break. inc. channels The interface looks at each incremental channel for the
idle voltage value of 2.5V with reference to common (pin
13). If this voltage is not present an error will be triggered
with this fault code. Solution: check all signal connections,
replace cable with new.
bdCba Cable break. abs. channels The interface looks at each data or clock channel for the
idle voltage value of 2.5V with reference to common (pin
13). If this voltage is not present an error will be triggered
with this fault code. Solution: check all signal connections,
replace cable with new.
PoSde Position deviation too high The position deviation between the incremental channels
and the absolute values is greater than 2.8 degrees. On
SIN/COS the comparison is made between occurrences of
the zero pulse. Too many or too few counts between the
zero pulse will trigger this error. Normally, this is caused by
a bad encoder cable and/or poor shielding and grounding
of the cable. Solution: replace the cable.
BdPPr Enc. ppr does not match Compares the internal value of ppr stored inside the
encoder with the setting of LF.2. If they do not match
this error code will be activated. Solution: verify correct
encoder ppr and enter it in LF.2.
BdInt Interface Card not
recognized
The serial interface card is not recognized by the main
CPU of the drive. Replace the feedback card.
bdSuP Bad internal enc. supply The internal power supply of the encoder has failed
OHEnc Encoder over heat Encoder temp is measure by the encoder and the error is
passed on to the drive via serial com.
OSEnc Encoder over speed Actual speed has exceeded the max speed of the
encoder.
ErEnc Internal encoder failure Internal encoder signals are incorrect or out of tolerance.
Replace the encoder
ErEnc Internal encoder failure Replace encoder
FrtEn Formatting the encoder The encoder will be formatted according to the prescribed
structure. This will allow further read/write cycles to
occur.
nEEnc New encoder found The feedback card has recognized that a new or different
encoder is now connected to the drive. Therefore
it is necessary to confirm. Reenter the values in
LF.26,LF.2,LF.
noFrt Encoder memory not
formatted
Encoder memory structure is not valid and therefore can
not be read
EncBS Encoder is busy The encoder is busy during data transfer and cannot accept
the transmission.
OFF No com to Enc. Card There is no communication between the encoder and
the drive.
