508 Fault tracing
A781
Motor fan
Programmable warning:
No feedback received from
external fan.
Check external fan (or other equipment
controlled) by the logic.
Check settings of parameters
.
A782
FEN temperature
Error in temperature
measurement when
temperature sensor (KTY or
PTC) connected to encoder
interface FEN-xx is used.
Check that parameter
setting corresponds to actual encoder
interface installation.
Check the settings of parameters
and
. Check that the corresponding
module is activated in parameters
. Use parameter
to validate
any changes in the settings.
Error in temperature
measurement when KTY
sensor connected to encoder
interface FEN-01 is used.
FEN-01 does not support temperature
measurement with KTY sensor. Use PTC
sensor or other encoder interface
module.
A783
Motor overload
Programmable warning:
Motor current is too high.
Check for overloaded motor.
Adjust the parameters used for the motor
overload function (
) and
.
A791
Brake resistor
Brake resistor broken or not
connected.
Check that a brake resistor has been
connected.
Check the condition of the brake resistor.
A793
BR excess
temperature
Brake resistor temperature has
exceeded warning limit defined
by parameter
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
Check warning limit setting, parameter
.
Check that the resistor has been
dimensioned correctly.
Check that braking cycle meets allowed
limits.
A794
BR data
Brake resistor data has not
been given.
One or more of the resistor data settings
(parameters
) is incorrect.
The parameter is specified by the
auxiliary code.
0000 0001 Resistance value too low.
.
0000 0002 Thermal time constant not
given.
.
0000 0003 Maximum continuous power
not given.
.
A797
Speed feedback
configuration
Speed feedback configuration
has changed.
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).
