Potential Cause Checking Method Corrective Actions
Parameter data error when
writing into EE- PROM. Examine the parameter settings. Please do
the following steps:
1.Press SHIFT key on the drive keypad, and
examine the parameter shown on LED
display.
2.If E320A is displayed (in
hexadecimal format), it indicates it is

of one
parameter has exceeded the
specified range. Correct the
setting value of the parameter
to clear the fault and restart the
servo drive.
2.If this fault occurs during
normal operation, it indicates
that the error occurs when
writing data
into EE-PROM. Turn ARST (DI
signal) ON to clear the fault or
restart the servo drive.
The setting value of hidden

accordance with the fault codes AL011,
AL024, AL025 and AL026. Perform the corrective actions
as described in AL011, AL024,
AL025 and AL026.
The output frequency for
pulse output may exceed
the limit of its allowable
setting value. Check if the following conditions occur:
Condition 1: Motor speed is above the value
set by P1-76.
Condition 2: Correctly set P1-76 andP1-46.
Ensure that the motor speed is
below the value set by P1-76.
