Chapter 10 Troubleshooting
: Emergency stop activated
Potential Cause
Emergency stop switch
is activated.
: Reverse (CWL) limit switch error
Potential Cause
Reverse limit switch is
activated.
Servo system is not
stable.
: Forward (CCWL) limit switch error
Potential Cause
Forward limit switch is
activated.
Servo system is not
stable.
: IGBT temperature error
Potential Cause
The drive has
exceeded its rated
load during
continuous operation.
Short-circuit at drive
output.
: Memory error
Potential Cause
Parameter data error
when writing into EE-
PROM.

Checking Method
Check if emergency stop switch is On
or Off.
Checking Method
Check if reverse limit switch is On or
Off.
Check the value of control parameter
setting and load inertia.
Checking Method
Check if forward limit switch is On or
Off.
Check the value of control parameter
setting and load inertia.
Checking Method
Check if there is overload or the motor
current is too high.
Check the drive input wiring.
Checking Method
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.
Corrective Actions
Activate emergency stop
switch.
Corrective Actions
Activate reverse limit switch.
Modify parameter setting and
re-estimate motor capacity.
Corrective Actions
Activate forward limit switch.
Modify parameter setting and
re-estimate motor capacity.
Corrective Actions
Increase motor capacity or
reduce load.
Ensure all wiring is correct.
Corrective Actions
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.
