Error no. C133n (n indicates the axis number (1 to 8).)
1Error list
C133n
(n indicates the
axis number (1
to 8).)
Error message Encoder battery voltage low
Cause The battery voltage supplied to the position detector dropped.
Measures Replace the backup battery. For more information about the replacement procedure, refer to the separate
volumes, "Instruction Manual/Robot Arm Setup to Maintenance".
Even if this warning occurs, unless the controller is re-turned on, it can operate perfectly. However, if the
battery consumption is intense, the Encoder ABS position data lost error (H112n) may occur when the
controller is re-turned on. It is recommended to replace the battery at the earliest opportunity.
C134n
(n indicates the
axis number (1
to 8).)
Error message Over-regeneration warning
Cause The regenerative level of the additional axis has risen to 80% or more.
Measures Check the regenerative capacity and parameters for the additional axis.
If it comes back, contact your service provider. Regeneration resistance may be disconnected.
C135n
(n indicates the
axis number (1
to 8).)
Error message Overload warning
Cause The overload level reached 95% or more.
Measures Check the load weight and the robot for collisions, etc.
H136n *
(n indicates the
axis number (1
to 8).)
Error message Absolute position counter error
Cause The counter of absolute position is illegal.
Measures Confirm whether the connection of encoder cable and the battery voltage of arm is falling.
C137n
(n indicates the
axis number (1
to 8).)
Error message Illegal parameter (servo)
Cause A parameter was set exceeding the setting range.
Measures The parameter has not been changed. Reset the correct value. If it comes back, contact your service
provider.
C138n
(n indicates the
axis number (1
to 8).)
Error message Removing control axis (servo)
Cause An instruction to remove the axis was issued by the controller.
Measures Cancel the instruction of removing axis.
H1390 Error message Emergency stop (Servo amplifier)
Cause The emergency stop command has been input from the RC
Measures Release the emergency stop state
C1400 Error message regeneration(AUX) frequency over
Cause Regeneration at the limit has occurred frequently
Measures Check the regeneration capacity
H1410 * Error message Instantaneous power interruption
Cause The power was momentarily interrupted
Measures Check power specification, and wiring of power and external emergency stop
C1420 Error message Over-regeneration warning
Cause The regeneration level reached 80％ or more.
Measures Lower the robot's movement speed.
If it comes back, contact your service provider. Regeneration resistance may be disconnected.
C1430 Error message Servo amplifier main circuit OFF
Cause The servo turned ON while the main circuit power was OFF
Measures Turn the main circuit power ON
H144n *
(n indicates the
axis number (1
to 8).)
Error message System error (servo 2)
Cause Trouble occurred in the current processing processor.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H1450 * Error message Instantaneous power interruption
Cause The power was momentarily interrupted at the power supply
Measures Check power specification, and wiring of power and external emergency stop
H1460 * Error message Power supply overcurrent
Cause Overcurrent in the power module in the power supply.
Measures Check the AC power line. If it comes back, contact your service provider.
