Fault cause and solution
Position values are being transferred to the encoder, encoder
and serial interface are working.
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.
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)
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)
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)
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.
The serial interface card is not recognized by the main CPU of
the drive. Replace the feedback card.
The internal power supply of the encoder has failed
Encoder temp is measure by the encoder and the error is passed
on to the drive via serial com.
Actual speed has exceeded the max speed of the encoder.
Internal encoder signals are incorrect or out of tolerance. Replace
the encoder
Replace encoder
The encoder will be formatted according to the prescribed
structure. This will allow further read/write cycles to occur.
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.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.
Encoder memory structure is not valid and therefore can not be
read
The encoder is busy during data transfer and cannot accept the
transmission.
There is no communication between the encoder and the
drive.
