Cause
The I/O extension module
types and locations specified
by parameters do not match
the detected configuration.
No motor speed feedback is
received.
0001 Motor gear definition invalid or
outside limits.
0002 Encoder not configured.
0003 Encoder stopped working.
0004 Encoder drift detected.
No load speed feedback is
received.
0001 Load gear definition invalid or
outside limits.
0002 Feed constant definition invalid
or outside limits.
0003 Encoder stopped working.
Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost.

What to do
Check the type and location settings of
the modules (parameters 14.01, 14.02,
15.01, 15.02, 16.01 and 16.02).
Check that the modules are properly
installed.
Check the auxiliary code. See Drive
application programming manual (IEC
61131-3) (3AUA0000127808 [English]).
Check the auxiliary code (format XXYY
ZZZZ). "XX" specifies the number of the
encoder interface module (01:
91.11/91.12, 02: 91.13/91.14), "YY"
specifies the encoder (01:
configuration, 02: 93 Encoder 2
configuration). "ZZZZ" indicates the
problem (see actions for each code
below).
Check motor gear settings
90.44).
Check encoder settings (92 Encoder 1
configuration or 93 Encoder 2
configuration).
Use parameter 91.10 Encoder parameter
refresh) to validate any changes in the
settings.
Check encoder status.
Check for slippage between encoder and
motor.
Check the auxiliary code (format XXYY
ZZZZ). "XX" specifies the number of the
encoder interface module (01:
91.11/91.12, 02: 91.13/91.14), "YY"
specifies the encoder (01:
configuration, 02: 93 Encoder 2
configuration). "ZZZZ" indicates the
problem (see actions for each code
below).
Check load gear settings (90.53
90.54).
Check feed constant settings
90.64).
Check encoder status.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups
Fieldbus adapter (FBA), 51 FBA A
settings, 52 FBA A data in
data out.
Check cable connections.
Check if communication master is able to
communicate.
