Disable the drive, control the resolver's contact,
reset the alarm, then enable the drive.
al14
following error
The error between the position reference
and the position feedback exceeds the
"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.
Disable the drive, check the Max Position Error
parameter, check the dynamic gains, reset the
alarm, then enable the drive.
al15
limit switch
The two fixed limit switches have both
been disabled or interrupted.
Disable the drive, check the limit limit switches
and external connections, then enable the drive.
al17
overcurrent regen resistance circuit
Possible short-circuit in the regen resist-
ance circuit.
This causes the opening of the Relè OK
contact and the disabling of the function-
ing.
Power off the drive, control the short-circuit, then
power on the drive.
al18
mechanical Brake
Overcurrent at the internal brake com-
mand or wrong connections.
Disconnect the power:
• control the external connections;

rameter on the "Motor" window;
then power up again.

but the aux24Vdc voltage is miss-
ing.
Disable the drive, connect the Auxiliary Voltage,
and then re-enable.
al21
phasing error or "wake & shake"
The auto-phasing was not successful and
causes the opening of the "Relay OK" contact
and blocks functioning.
Disable the converter and check for friction or mec-
chanical blockages on the axis.
al22
"sef-iN" alarm
The 24Vdc has been removed form the input
"SEF-IN" during functioning. The motor stops
in an uncontrolled manner.
This open the "Relay Ok" contact and blocks
functioning.
Disable the converter and check why the 24Vdc is missing
on the input "SEF-IN".
al23
flash alarm
Errors in reading/writing parameters on
the Flash memory, or Flash memory is
empty.
Disable the drive, save new values, then
re-enable. If the problem persists contact Axor.
al24 can Bus alarm
Error during communication on CANBus.
Disable the drive, check the cabling and
re-enable. If the problem persists contact Axor.
al26
homing error
