13-6 Troubleshooting 3AXD50000011888
Table 13-1 Warning Messages (Alphabetical by Keypad Text)
Warning Fault # Cause What to do
Mechanical brake
opening not allowed
Programmable warning:
44.17 Brake fault function
A7A5 Open conditions of
mechanical brake
cannot be fullled (for
example, brake has been
prevented from opening
by parameter 44.11 Keep
brake closed).
Check mechanical brake settings in parameter group 44
Mechanical brake control (especially 44.11 Keep brake
closed).
Check that acknowledgement signal (if used) matches
actual status of brake.
FIO-11 AI
parametrization
A7AA The hardware current/
voltage setting of an
analog input (on an
I/O extension module)
does not correspond to
parameter settings.
Check the event log for an auxiliary code (format 0000
XXYY). “XX” species the number of the I/O extension
module (01: parameter group 14 I/O extension module
1, 02: 15 I/O extension module 2, 03: 16 I/O extension
module 3). “YY” species the analog input on the module.
For example, in case of I/O extension module 1, analog
input AI1 (auxiliary code 0000 0101), the hardware
current/voltage setting on the module is shown by
parameter 14.29. The corresponding parameter setting is
14.30. Adjust either the hardware setting on the module
or the parameter to solve the mismatch.
Note: Control board reboot (either by cycling the power or
through parameter 96.08 Control board boot) is required
to validate any changes in the hardware settings.
Extension I/O
conguration failure
A7AB The I/O extension module
types and locations
specied by parameters
do not match the detected
conguration.
Check the event log for an auxiliary code. The code
indicates which I/O extension module is affected.
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.
Motor speed
feedback
Programmable warning:
90.45 Motor feedback fault
A7B0 No motor speed feedback
is received.
Check the event log for an auxiliary code (format XXYY
ZZZZ). “XX” species the number of the encoder interface
module (01: 91.11/91.12, 02: 91.13/91.14), “YY” species
the encoder (01: 92 Encoder 1 conguration, 02: 93
Encoder 2 conguration). “ZZZZ” indicates the problem
(see actions for each code below).
0001 Motor gear denition
invalid or outside limits.
Check motor gear settings (90.43 and 90.44).
0002 Encoder not congured. Check encoder settings (92 Encoder 1 conguration or 93
Encoder 2 conguration).
Use parameter 91.10 Encoder parameter refresh) to
validate any changes in the settings.
0003 Encoder stopped working. Check encoder status.
0004 Encoder drift detected. Check for slippage between encoder and motor.
FBA A
communication
Programmable warning:
50.02 FBA A comm loss func
A7C1 Cyclical communication
between drive and
eldbus adapter module
A or between PLC and
eldbus adapter
module A is lost.
Check status of eldbus communication. See user
documentation of eldbus interface.
Check settings of parameter groups 50 Fieldbus adapter
(FBA), 51 FBA A settings, 52 FBA A data in and 53 FBA A
data out.
Check cable connections.
Check if communication master is able to communicate.
FBA B
communication
Programmable warning:
50.32 FBA B comm loss func
A7C2 Cyclical communication
between drive and
eldbus adapter module
B or between PLC and
eldbus adapter
module B is lost.
Check status of eldbus communication. See user
documentation of eldbus interface.
Check settings of parameter group 50 Fieldbus adapter
(FBA).
Check cable connections.
Check if communication master is able to communicate.
DDCS controller
comm loss
Programmable warning:
60.59 DDCS controller
comm loss function
A7CA DDCS (ber optic)
communication between
drive and external
controller is lost.
Check status of controller. See user documentation of
controller.
Check settings of parameter group 60 DDCS
communication.
Check cable connections. If necessary, replace cables.
