AL022
: Main circuit power leak phase
Causes
Checking Method
Corrective Actions
The main circuit power
is abnormal
Check if the power cable is loose
or there is one single phase input
only.
Apply the three-phase power. If it
is still abnormal, please send the
drive back to the distributors or
contact with Delta.
AL023
: Early warning for overload
Causes
Checking Method
Corrective Actions
Early warning for
overload
1. Check if it is used in overload
condition.
2.
Check if the value of
parameter P1-56 is set to
small.
1. Please refer to the corrective
actions of AL006.
2. Please increase the setting
value of parameter P1-56. Or
set the value over 100 and
deactivate the overload
warning function.
AL024:
Encoder initial magnetic field error
Causes
Checking Method
Corrective Actions
The initial magnetic
field of the encoder is
in error
(Signal U, V, W of the
encoder magnetic field
is in error.)
1. Check if the servo is properly
grounded.
2. Check if the encoder cable
separates from the power
supply or the high-current
circuit to avoid the
interference.
3. Check if the shielding cables
are used in the wiring of the
encoder.
If the situation is not improving,
please send the drive back to the
distributors or contact with Delta.
