No. Error
Description Troubleshooting
1
Left SW limit
or
The set left software limit is reached, and
move to the left.
2
Right SW limit
or
The set right software limit is reached, and the motor can no
longer move to the right.
3
Left HW limit
W03 HWLL
or
WRN W03
The hardware limit switch on the left side has been detected and
the motor can no longer move to the left.
(1) If the hardware limit is not connected to the drive and the
false trigger occurs, cancel the enable of hardware limit.
(2) If it is confirmed that the limit switch is not actually triggered,
check that the wiring or actuation logic is correct.
4
Right HW limit
W04 HWRL
or
WRN W04
The hardware limit switch on the right side has been detected and
the motor can no longer move to the right.
(1) If the hardware limit is not connected to the drive and the
false trigger occurs, cancel the enable of hardware limit.
(2) If it is confirmed that the limit switch is not actually triggered,
check that the wiring or actuation logic is correct.
5
Servo voltage big
W05 SVBIG
or
WRN W05
The drive’s PWM output switch is greater than the limit value and
the current output cannot be increased. If this warning continues
occurring in the position control, the error of “E03 PEBIG” will
(1) Change the power source to 220 V.
(2) Reduce the speed, acceleration, or deceleration.
6
Position error
warning
W06 PE
or
WRN W06
The position error exceeds the set warning window for position
error.
(1) Check that the servo gain is properly tuned.
(2) Check if the warning threshold is set too small.
(3) Sometimes, this phenomenon may occur since the
maintenance period is over or the lubrication is not
implemented.
7
Velocity error
warning
W07 VE
or
WRN W07
The velocity error exceeds the set warning window for velocity
error.
(1) Check that the servo gain is properly tuned.
(2) Check if the warning threshold is set too small.
(3) Sometimes, this phenomenon may occur since the
maintenance period is over or the lubrication is not
8
Current Limited
W08 CUR.L
or
WRN W08
The current has saturated in the specification of motor peak
current. If this warning continues occurring, the error of “E05
SWHOT” will happen and the motor will be disabled.
(1) Reduce the speed, acceleration, or deceleration.
(2) Decrease the load.
9
Acceleration
Limited
W09 ACC.L
or
In the position mode or velocity mode, the acceleration protection
setting is reached when the motor is moving.
