AL.58 Excessive position deviation after initial magnetic field detection
Alarm cause Checking method Corrective action
During initial magnetic field
detection, it will check if the
position deviation is within the
range. If not, AL.58 occurs. 1. check if the command is
issued right after the
power is applied
2. check if the move
distance is too far during
initial magnetic detection 1.Do not input the
command right after
apply power to the
servo.
2.Decrease
PL12(the magnetic
detection current).
AL.1A Undefined index coordinate
Alarm cause Checking method Corrective action
When using the indexing function,
you need to execute homing to
define the starting point of the
indexing coordinates. otherwise,
an alarm will occur. Check whether homing
has been executed. 1. Before operating

function, make sure
execute homing first
to avoid this alarm.
2. Use DI:Alm reset
function to clear the
alarm when alarm
occurs.
3. This alarm can
also be cleared
when Servo is ON.
AL.1B Position shift warning
Alarm cause Checking method Corrective action
When DO: MC_OK is already on,
and then MC_OK signal turns off.
Please refer to PD28 description. When DO:MC_OK is
already on, it may turn off
when DO:INP turns off,
The external force after
motor completed
positioning may cause
the position shift. 1. Turn on RES
signal.
2. Press Set button at
alarm display screen.
3. Restart the power.
