AL014: Reverse limit error
Causes Checking Method Corrective Actions
Reverse limit switch is
activated.
Check if the limit switch is enabled. Enable the reverse limit switch.
The servo system is
unstable.
Check the control parameter and
inertia ratio.
Re-adjust the parameter or
evaluate the motor capacity.
AL015: Forward limit error
Causes Checking Method Corrective Actions
Forward limit switch is
activated.
Check if the limit switch is enabled. Enable the forward limit switch.
The servo system is
unstable.
Check the control parameter and
inertia ratio.
Re-adjust the parameter or
evaluate the motor capacity.
AL016: IGBT Overheat
Causes Checking Method Corrective Actions
Over the rated
loading of the drive
and continuously
excessive using
Check if it is overloading or the
motor current is too high.
Increase the motor capacity or
reduce the load.
The drive output is
short-circuit
Check the drive output wiring. Correct wiring
AL017: Abnormal EEPROM
Causes Checking Method Corrective Actions
It is in error when
DSP accesses
EEPROM.
Press the SHIFT Key on the panel
and it shows EXGAB.
X = 1, 2, 3
G = group code of the parameter
AB = hexadecimal of the parameter
If it shows E320A, it means it is
parameter P2-10; If it shows
E3610, it means it is parameter P6-
16. Please check the parameter.
The fault occurs when applying
to the power. It means one of
the parameters is over the
reasonable range. Please re-
power on after adjusting.
The fault occurs in normal
operation. It means it is in error
when writing the parameter.
The alarm can be cleared by
DI.ARST.
Abnormal hidden
parameter
Press the SHIFT Key on the panel
and it shows E100X.
The fault occurs in parameter
reset. The setting of the drive is
wrong. Please set the correct
type of the drive.
Data in ROM is
damaged.
Press the SHIFT Key on the panel
and it shows E0001.
The fault occurs when it is
servo-on. Usually it is because
the data in ROM is damaged or
there is no data in ROM.
Please send the drive back to
the distributors or contact
Delta.
