356 Fault tracing
A7CA DDCS controller
comm loss
Programmable warning:
DDCS (fiber optic)
communication between drive
and external controller is lost.
Check status of controller. See user
documentation of controller.
Check settings of parameter group
Check cable connections. If necessary,
replace cables.
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
:
), “YY” specifies the encoder
(
01:
). “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.
See also parameter
0002 No encoder signal
Check the condition of the encoder.
0003 Overspeed
Contact your local ABB representative.
0004 Overfrequency
Contact your local ABB representative.
0007 Speed scaling 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.
000E Encoder reported a position
counter error
See the documentation of the encoder.
000F Encoder reported an internal
error
See the documentation of the encoder.
