Error no. H064n * (n indicates the axis number (1 to 8).) 1-12
H064n *
(n indicates the
axis number (1
to 8).)
Error message System error (ABS CPU)
Cause An error in the CPU of the absolute position linear scale was detected.
Measures 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.
H065n *
(n indicates the
axis number (1
to 8).)
Error message Absolute position error
Cause An error was detected in the absolute position detection circuit within the absolute position linear scale.
Measures 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.
H066n *
(n indicates the
axis number (1
to 8).)
Error message Incremental position error
Cause An error was detected in the relative position detection circuit within the absolute position linear scale.
Measures 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.
H067n *
(n indicates the
axis number (1
to 8).)
Error message Encoder CPU error
Cause An error was detected in the CPU of the position detector.
Measures 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.
H068n *
(n indicates the
axis number (1
to 8).)
Error message Encoder LED error
Cause Deterioration of the position detector's LED was detected.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H0690 * Error message Regeneration circuit error
Cause A regenerative transistor or resistor error was detected. This error may also occur when the power supply
voltage is high.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H0700 * Error message P.S. external contactor fusing
Cause The contactor was turned ON even though READY is OFF.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H0710 * Error message Servo amp. relay error.
Cause The relay on servo cpu card did not turn ON.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H0711 * Error message Discharge resistance relay error
Cause Discharge resistance circuit on converter is state-of-discharge
Measures Turn the power OFF and ON once
H0712 * Error message Converter fuse fusing
Cause Fuse of a converter fused for a ground fault or short circuit
Measures 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 required", for details. (On details of
the 3.2 A fuse, contact the manufacturer.)
If no improvement is made after carrying out the above measures, please contact the manufacturer.
H0713 * Error message Encoder power supply fuse trip
Cause Encoder power supply fuse tripped by ground fault, short circuit
Measures Turn the power OFF, wait a while, and then turn ON again
H0720 * Error message Power supply watch dog
Cause The converter software process did not end within the specified time.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
