Error no. H066n * (n indicates the axis number (1 to 8).) 1-10
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
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 Power supply relay error
Cause The discharge relay on converter card did not turn ON
Measures Turn the power OFF and ON once
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.
H0730 * Error message Power supply rush relay fusing
Cause The rush resistance short-circuit relay did not turn OFF.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H0740 * Error message Power supply main circuit error
Cause The charge operation of the main circuit capacitor is not normal.
Connection of the external emergency stop has the mistake.
Measures Turn the power OFF and ON once.
Confirm that the power supply voltage is in the specification value and the connection of the external
emergency stop is correct.
If it comes back, confirm the time of occurrence of this error being "servo ON/OFF", or being "power sup
-
ply OFF/ON", and contact your service provider
H0742 Error message Power supply main circuit error
Cause A main circuit voltage has decreased because of a failure of the Safety relay on a converter card.
Measures Turn the power OFF and ON once.
Confirm whether there is any problem in wiring of the external emergency stop switch.
Refer to the "Examples of safety measures" given in separate "Standard Specifications Manual" for exter
-
nal emergency stop switch wiring.
If it comes back, contact to your service provider.
H0743 * Error message Power supply main circuit error3.
Cause A main circuit voltage has decreased because of contactor fail.
Measures Turns off the power once and turns on on the power supply again. Confirm power supply voltage and the
connection of the external emergency stop. When it comes back, contact to the dealer.
