Description
Troubleshooting
1
Left SW limit
W01 SWLL
or
WRN W01
The set left software limit is reached, and the motor can no
longer move to the left.
2
Right SW limit
W02 SWRL
or
WRN W02
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 happen.
(1) Change the power source to 220 V if 110 V is used
currently.
(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
implemented.
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.
