Please refer to "Operation manual".
3.2.

Cases Where There is No Error Message

No error message is issued for low urgency problems. (Like burning out of an indicator
lamp bulb)
For problems of this type, correctly determine the occurrence situation (Problem) and
then select the pertinent item from the table below, and take measures.
Problem
(Occurring
Phenomenon)
Main power lamp does
not light up
Nothing appears on
the touch panel
screen.
Motor power display
lamp does not light up Burn out of indicator lamp bulb.
Motor power does not
switch on
Arm movement is not
smooth
Cause
Burn out of main power supply lamp.
Burn out of DC24V power supply
(AWR2).
Tripping of breaker (NFB1,NFB2).
Measure voltage at the load side
terminals RX3 and SX3 of the noise filter
(NF2).
Normal if within the range of
AC 200V ±10%.
Measure voltage on the secondary side
(R,S,T) of the main NFB(NFB0).
Normal if within the range of ±10% of
the rated voltage.
Check the voltage on AVR2 (normal if
24V).
Defective connection of connector.
Turn on the main power and check if the
letter [check] appears on touch panel.
Check DC24V power supply (AVR2).
Check the motor power ON condition in
maintenance mode menu.
Defective magnet switch (MS1).
Check the weight parameters
-Hand weight(system parameter)
-Article weight(program parameter)
Acceleration time is too short.
Time scaling parameter (program
parameter) is too small.
Check if the mechanical parts are
Replace lamp.
Replace AWR2.
Switch on again.
Correct supplied power.
Reconsider and modify transformer
capacity and cable size.
Correct supplied power.
Reconsider and modify transformer
capacity and cable size.
Replace AVR2 if the voltage is
abnormal.
If the voltage is normal, replace touch
panel.
Check harness.
Check connector.
Check the voltage on AVR1 (normal if
5V). Replace AVR1 if the voltage is
abnormal.
Replace AVR2.
Replace lamp bulb.
If RC103 ON enable can not be turned
on, turn off main power supply.
Replace magnet switch (MS1).
Input the correct value.
Basically input the value in the standard
program
Basically input 0 for the time scaling
parameter. If having margin in motor
torque, it can be turned down to –25.
Replace the defective parts.
