Fault tracing 513
A7CB MF comm loss
Programmable warning:
Master/follower
communication is lost.
Check the auxiliary code. The code
indicates which node address (defined by
parameter
in each drive) on the
master/follower link is affected.
Check settings of parameter group
.
On the FDCO module (if present), check
that the DDCS link switch is not set to 0
(OFF).
Check cable connections. If necessary,
replace cables.
A7CE EFB comm loss
Programmable warning:
Communication break in
embedded fieldbus (EFB)
communication.
Check the status of the fieldbus master
(online/offline/error etc.).
Check cable connections to the XD2D
connector on the control unit.
A7E1
Encoder
Programmable warning:
Encoder error.
Check the auxiliary code (format XXYY
ZZZZ). “XX” specifies the number of the
encoder interface module (
01
:
02
), “YY”
specifies the encoder (
01:
,
02:
). “ZZZZ” indicates the
problem (see actions for each code
below).
0001 Cable fault
Check the conductor order at both ends
of the encoder cable.
Check the groundings of the encoder
cable.
If the encoder was working previously,
check the encoder, encoder cable and
encoder interface module for damage.

0002 No encoder signal
Check the condition of the encoder.
0003 Overspeed
Contact your local ABB representative.
0004 Overfrequency
Contact your local ABB representative.
0005 Resolver ID run failed
Contact your local ABB representative.
0006 Resolver overcurrent fault
Contact your local ABB representative.
0007 Speed scaling error
Contact your local ABB representative.
0008 Absolute encoder
communication error
Contact your local ABB representative.
0009 Absolute encoder initialization
error
Contact your local ABB representative.
000A Absolute SSI encoder
configuration error
Contact your local ABB representative.
000B Encoder reported an internal
error
See the documentation of the encoder.
000C Encoder reported a battery
error
See the documentation of the encoder.
000D Encoder reported overspeed
or decreased resolution due to
overspeed
See the documentation of the encoder.
