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. 1)
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. 1)
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. 1)
BdPPr
Enc. ppr does not match
Compares the internal value of ppr stored inside the encoder
with the setting of LF.27. If they do not match this error code
will be activated. Solution: verify correct encoder ppr and enter
it in LF.27.
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 con rm.
Reenter the values in LF.26,LF.27,LF.77. This message can also
occur if the cable is incorrectly wired or the encoder is damaged.
Try to swap the cables or encoders in this case.
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.
1) If the cable is coiled up in the control panel, try uncoiling it out onto the oor in case this is the problem.
