:
Reverse (CWL) limit switch error
Potential Cause
Checking Method
Corrective Actions
Reverse limit switch is
activated.
Check if reverse limit switch is On or Off. Activate reverse limit switch.
Servo system is not
stable.
Check the value of control parameter
setting and load inertia.
Modify parameter setting and
re-estimate motor capacity.
:
Forward (CCWL) limit switch error
Potential Cause
Checking Method
Corrective Actions
Forward limit switch is
activated.
Check if forward limit switch is On or Off. Activate forward limit switch.
Servo system is not
stable.
Check the value of control parameter
setting and load inertia.
Modify parameter setting and
re-estimate motor capacity.
:
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.
