ALARM DESCRIPTION CORRECTIVE ACTION
A5.1
Radiator
temperature too
high
The radiator temperature (d25) is
higher than the maximum (P118).
Check the temperature reading on d25 and then check the
radiator. If -273.15 is displayed, the electrical connection
towards the radiator heat probe has been interrupted. If the
reading is correct and the motor is overheating, check that the
drive cooling circuit is intact. Check the fan, its power unit, the
vents, and the air inlet filters on the cabinet. Replace or clean
as necessary. Ensure that the ambient temperature around the
drive is within the limits permitted by its technical
characteristics.
Check parameter P118 is set correctly.
A5.2
Brake
resistance
adiabatic
energy
protection
The Adiabatic Energy
dissipated on Braking
resistance during the time
selected in P144 has
overcame the threshold set
in KJoule in P142
Check the correct setting of parameters P140, P142 and
P144 compared to the Resistance plate. Check the correct
dimensioning of Braking Resistance Maximum Power
related to maximum speed, load inertia and braking time.
A5.3
Brake
resistance
dissipated
power
The Average Power
dissipated on Braking has
overcome the threshold set
in Watt in P146
Check the correct setting of parameters P140, P146 and
P148 compared to the Resistance plate. Check the correct
dimensioning of Braking Resistance Average Power
related to maximum speed, load inertia and braking time
A5.4
Motor thermal
probe not
connected
Thermal probe not detected the
presence.
Verify the presence of the connection of the probe and that it is
correct.
A6.0
Motor I
2
t
thermal alarm
The motor electronic overload
safety switch has cut in due to
excessive current absorption for
an extensive period.
Check the motor load. Reducing it may prevent the safety
switch cutting in.
Check the thermal current setting, and correct if necessary
(P70). Check that the heat constant value is long enough (P71).
Check that the safety heat curve suits the motor type and
change the curve if necessary (C33).
A7.0
Auto-tuning test
unfinished
The RUN command was disabled
during a test. Run command
switched off too early.
Reset the alarms and repeat the test by re-enabling it.
A8.0
Missing enable
logic input from
the field
A digital input has been
configured to I02 logical input
function and this input is in not
active state
The external safety switch has cut in disabling drive enable.
Restore and reset.
The connection has been broken. Check and eliminate the fault.
Input function has been assigned, but enable has not been
given. Authorise or do not assign the function.
A8.1
Watchdog
alarm LogicLab
A LogicLab watchdog alarm on
slow cycle appears
Check if the LogicLab slow task duration is greater than 500 ms
and try to reduce this execution time
A8.2
Fast task
LogicLab too
long
The logicLab fast task is too long
in time
Try to reduce the LogicLab fast task execution time under
admitted limit.
Please refer to the specific documentation.
A8.3
Application out
of service
There is no valid application
running in the drive
Reload the application using OPDExplorer
A9.0
Hardware
board and
firmware are
incompatible
Feedback option card and drive
firmware
incompatible
Check internal values d62 and d63 for the firmware and option
card codes. There must be some irregularity.
A9.1
Sensor
presence
Sensor not connected Check the connection towards the sensor.
A9.2
Overspeed
(more than 10
consecutive
Tpwm)
Overspeed: speed reading higher
than threshold set in P52.
In a transient state, the speed reading has exceeded the
permitted limit. Adjust the speed regulator gains or raise the
limit in P52.
