ENCODER
Encoder feedback fault
If an absolute encoder,
EnDat/Hiperface/SSI, with
incremental sin/cos pulses is used,
incorrect wiring can be located as
follows: Disable serial link (zero
position) by setting parameter
ABS ENC INTERF to
and test encoder operation:
• If the encoder fault is not
activated, check the serial link
data wiring. Note that zero
position is not taken into account
when the serial link is disabled.
• If the encoder fault is activated,
check the serial link and sin/cos
signal wiring.
Note:
Because only zero position is
requested through serial link and
during run, the position is updated
according to sin/cos pulses.
• Check encoder parameter
settings.
If the fault appears after encoder
feedback has already been used or
during a drive run:
• Check that the encoder
connection wiring or encoder is
not damaged.
• Check that encoder interface
module (FEN-xx) connection or
module is not damaged.
• Check earthings (when
disturbances are detected in
communication between the
encoder interface module and
the encoder).
