activated.
The servo system is
unstable.
AL015：Forward Limit Error
Causes
Forward limit switch is
activated.
The servo system is
unstable.
AL016：IGBT Overheat
Causes
Over the rated loading of
the drive and
continuously excessive
using
The drive output is short-
circuit
AL017：Abnormal EEPROM
Causes
It is in error when DSP
accesses EEPROM.
Abnormal hidden
parameter
Data in ROM is
damaged.
Revision February, 2017
Checking Method
Check if the limit switch is enabled. Enable the reverse limit switch
Check the control parameter and
inertia ratio
Checking Method
Check if the limit switch is enabled.
Check the control parameter and
inertia ratio
Checking Method
Check if it is overloading or the
motor current is too high.
Check the drive output wiring
Checking Method
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.
Press the SHIFT Key on the panel
and it shows E100X
Press the SHIFT Key on the panel
and it shows E0001
Corrective Actions
Re-adjust the parameter or
evaluate the motor capacity.
Corrective Actions
Enable the forward limit switch
Re-adjust the parameter or
evaluate the motor capacity.
Corrective Actions
Increase the motor capacity or
reduce the load.
Correct wiring
Corrective Actions
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.
The fault occurs in parameter reset.
The setting of the drive is wrong.
Please set the correct type of the
drive.
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
with Delta.
