between PLC and fieldbus adapter
module B is lost.
Check settings of parameter group 50
Fieldbus adapter (FBA).
Check cable connections.
Check if communication master is able
to communicate.
Check status of controller. See user
documentation of controller.
DDCS (fiber optic) communication
between drive and external controller is
lost.

Check settings of parameter group 60
DDCS communication.
Check cable connections. If necessary,
replace cables.
Check the auxiliary code. The code
indicates which node address (defined
Master/follower communication is lost.M/F comm lossA7CB
by parameter 60.2 in each drive) on the
master/follower link is affected.
Check settings of parameter group 60
DDCS communication.
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.
Check the status of the fieldbus master
(online/offline/error etc.).
Communication break in embedded
fieldbus (EFB) communication.

Check cable connections to the XD2D
connector on the control unit.
Check the auxiliary code (format XXYY
ZZZZ). “XX” specifies the number of the
Encoder error.EncoderA7E1
encoder interface module (01:
91.11/91.12, 02: 91.13/91.14), “YY”
specifies the encoder (01: 92 Encoder 1
configuration, 02: 93 Encoder 2
configuration). “ZZZZ” indicates the
problem (see actions for each code
below).
Check the conductor order at both
ends of the encoder cable.
Cable fault.0001
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 92.21 Encoder
cable fault mode.
Check the condition of the encoder.No encoder signal.0002
