430 Fault tracing
7358 Line side converter faulted The supply unit has tripped
on a fault. If using a control panel or the Drive
composer tool, connect to the
supply unit to read the fault code.
Refer to the firmware manual of the
supply unit for instructions related
to the code.
7380 Encoder internal Internal fault. Contact your local ABB
representative.
7381 Encoder 1
Programmable fault: 90.45
Motor feedback fault
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
91.02 to 0 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, 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:
- 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).
