Resolver alarm
al12
Missing resolver power supply/signal.
following error
The error between the position reference
and the position feedback exceeds the
al14
"Max Position Error" parameter, because
the "Max Position Error" parameter is too
small, or the dynamic gains of the veloc-
ity-positioning loop are wrong.
limit switch
al15 The two fixed limit switches have both
been disabled or interrupted.
overcurrent regen resistance circuit
Possible short-circuit in the regen resist-
ance circuit.
al17
This causes the opening of the Relè OK
contact and the disabling of the function-
ing.
mechanical Brake
Overcurrent at the internal brake com-
mand or wrong connections.
al18
in-rush Bus
24 This is not an alarm.
up Indication of the drive's in-rush phase or
the lack of the main power supply.
auxiliary voltage
Presence of the main supply (L1, L2, L3),
al20
but the auxiliary +24Vdc voltage is miss-
ing.
phasing error or "wake & shake"
The auto-phasing was not successful and
al21
causes the opening of the "Relay OK" contact
and blocks functioning.
"sef-iN" alarm
The 24Vdc has been removed form the input
"SEF-IN" during functioning. The motor stops
al22
in an uncontrolled manner.
This open the "Relay Ok" contact and blocks
functioning.
flash alarm
Errors in reading/writing parameters on
al23
the Flash memory, or Flash memory is
empty.
can Bus alarm
al24
Error during communication on CANBus.
homing error
Position error too high during the homing
al26
procedure.
The motor stops, but it is not disabled.

3.2 Alarms
Disable the drive, control the resolver's contact,
reset the alarm, then enable the drive.
Disable the drive, check the Max Position Error
parameter, check the dynamic gains, reset the
alarm, then enable the drive.
Disable the drive, check the limit limit switches
and external connections, then enable the drive.
Power off the drive, control the short-circuit, then
power on the drive.
Disconnect the power:
• control the external connections;
• control the current absorption of the motor
brake;
• verify the settings of the "Holding Brake" pa-
rameter on the "Motor" window;
then power up again.
Disable the drive, connect the Auxiliary Voltage,
and then re-enable.
Disable the converter and check for friction or mec-
chanical blockages on the axis.
Disable the converter and check why the 24Vdc is missing
on the input "SEF-IN".
Disable the drive, save new values, then
re-enable. If the problem persists contact Axor.
Disable the drive, check the cabling and
re-enable. If the problem persists contact Axor.
Check the homing setup, then reset the alarm
using the "Start Homing" function.
