An error in the CPU of the absolute position linear scale was detected.
Turn the power OFF and ON once. Also, carefully check whether there is no deviation in the operating
position of the robot. If it is deviated, set the origin position (OP) again. For more information about the
operating procedure, refer to the separate volume, "Instruction Manual/Robot Arm Setup to Maintenance."
If it comes back, contact your service provider.
An error was detected in the absolute position detection circuit within the absolute position linear scale.
Turn the power OFF and ON once. Also, carefully check whether there is no deviation in the operating
position of the robot. If it is deviated, set the origin position (OP) again. For more information about the
operating procedure, refer to the separate volume, "Instruction Manual/Robot Arm Setup to Maintenance."
If it comes back, contact your service provider.
An error was detected in the relative position detection circuit within the absolute position linear scale.
Turn the power OFF and ON once. Also, carefully check whether there is no deviation in the operating
position of the robot. If it is deviated, set the origin position (OP) again. For more information about the
operating procedure, refer to the separate volume, "Instruction Manual/Robot Arm Setup to Maintenance."

Deterioration of the position detector's LED was detected.
Turn the power OFF and ON once. If it comes back, contact your service provider.
A regenerative transistor or resistor error was detected. This error may also occur when the power supply
voltage is high.
Turn the power OFF and ON once. If it comes back, contact your service provider.
The contactor was turned ON even though READY is OFF.
Turn the power OFF and ON once. If it comes back, contact your service provider.
The relay on servo cpu card did not turn ON.
Turn the power OFF and ON once. If it comes back, contact your service provider.
Discharge resistance circuit on converter is state-of-discharge
Turn the power OFF and ON once
Fuse of a converter fused for a ground fault or short circuit
Please exchange a fuse of a converter
Investigate and correct the ground fault or short circuit portion in the wiring made by the customer. Then,
replace the 3.2 A fuse inside the controller.
Refer to Page 74, "2.1.4 Place where a converter fuse replacement is
the 3.2 A fuse, contact the manufacturer.)
If no improvement is made after carrying out the above measures, please contact the manufacturer.
Encoder power supply fuse tripped by ground fault, short circuit
Turn the power OFF, wait a while, and then turn ON again
The converter software process did not end within the specified time.
Turn the power OFF and ON once. If it comes back, contact your service provider.
