Chapter 10 Troubleshooting
: IGBT temperature error
Potential Cause Checking Method Corrective Actions
The drive has
exceeded its rated
load during
continuous
operation.
Check if there is overload or the motor
current is too high.
Increase motor capacity or
reduce load.
Short-circuit at drive
output.
Check the drive input wiring. Ensure all wiring is correct.
: Memory error
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 parameter P2-
10. Please examine the parameter
settings of P2-10.
3. If E3610 is displayed (in hexadecimal
format), it indicates it is parameter P6-
16. Please examine the parameter
settings of P6-16.
1. If this fault occurs when
power is applied to the
drive, it indicates that the
setting value 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 parameter is
in error.
Press SHIFT key on the drive keypad and
examine if E100X is displayed on LED
display.
If this fault occurs when
resetting the parameter
settings, it indicates that the
servo drive type is not set
correctly. Correctly set the
servo drive type again.
Data in EE-PROM is
damaged.
Press SHIFT key on the drive keypad and
examine if E0001 is displayed on LED
display.
If this fault occurs when power
is applied to the drive, it
indicates that the data in EE-
RPM is damaged or there is no
data in EE-PROM. Please
contact your distributor for
assistance or contact with
Delta.
