CTRL LAW SWITCHING
ORDER ERROR (SV)
Sub code: specifies the axis that
alarm occurred.
Servo control board failure
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
1684
INSTANT POWER
FAILURE
(TRQ)(SV)
The instant power failure occurred
and then the torque was
saturated.
Voltage failure
Check if the primary power supply voltage is dropping.
Power failure
Check if the instant power failure has occurred.
1685
INSTANT POWER
FAILURE
(TIME)(SV)
The instant power failure occurred
for longer than the certain time
period.
Voltage failure
Check if the primary power supply voltage is dropping.
Power failure
Check if the instant power failure has occurred.
1686
POS.DEVITATION
SATURATING ERROR
(SV)
Setting error
Check the settings for manipulator motion condition (influence by external
force, load condition).
Connection failure
Check if a ground fault has not occurred in the U-, V-, and W-phase of motor
power line, or short circuit has not occurred between these phases.
Connection failure
Check the connection of motor power line.
Module failure (motor)
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the motor.
Servo control board failure
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
Module failure
(amplifier)
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.

Amplifier board not
installed
Sub Code: Signifies the axis in
which the alarm occurred
Setting error
(1)Check the following settings.
Check if the amplifier module is correctly mounted.
Module failure (amplifier)
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the controller. Save the CMOS.BIN before
replacement to be safe.
Servo control board failure
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the controller. Save the CMOS.BIN before
