: Emergency stop activated
Potential Cause Checking Method Corrective Actions
Emergency stop switch
is activated. Check if emergency stop switch is On
or Off. Activate emergency stop
switch.
: 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.
