ENCODER1
(0x7301)
Encoder 1 feedback fault
If fault appears during first start-up before
encoder feedback is used:
- Check cable between encoder and encoder
interface module (FEN-xx) and order of
connector signal wires at both ends of cable.
If 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
to
and test encoder operation:
- If encoder fault is not activated, check serial
link data wiring. Note that zero position is not
taken into account when serial link is
disabled.
- If encoder fault is activated, check serial link
and sin/cos signal wiring.
Note:
Because only zero position is
requested through serial link and during run,
position is updated according to sin/cos
pulses.
- Check encoder parameter settings.
If fault appears after encoder feedback has
already been used or during drive run:
- Check that 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 encoder
interface module and encoder).
