Fault tracing 511
A7A2
Mechanical brake
opening failed
Programmable warning:
Status of mechanical brake
acknowledgement is not as
expected during brake open.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
Check that acknowledgement signal
matches actual status of brake.
A7A5
Mechanical brake
opening not allowed
Programmable warning:
Open conditions of mechanical
brake cannot be fulfilled (for
example, brake has been
prevented from opening by
parameter
).
Check mechanical brake settings in
parameter group
(especially
).
Check that acknowledgement signal (if
used) matches actual status of brake.
A7AA Extension AI
parameterization
The hardware current/voltage
setting of an analog input (on
an I/O extension module) does
not correspond to parameter
settings.
Check the auxiliary code (format
XX00 00YY). “XX” specifies the number
of the I/O extension module (
01:
parameter group
02:
,
03:
). “YY”
specifies 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
. The
corresponding parameter setting is
. 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
) is required to
validate any changes in the hardware
settings.
A7AB Extension I/O
configuration failure
The I/O extension module
types and locations specified
by parameters do not match
the detected configuration.
Check the type and location settings of
the modules (parameters
,
and
Check that the modules are properly
installed.
Check the auxiliary code. See
Drive
application programming manual (IEC
61131-3)
(3AUA0000127808 [English]).
A7B0
Motor speed feedback
Programmable warning:
No motor speed feedback is
received.
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 Motor gear definition invalid or
outside limits.
Check motor gear settings (
