Error no. C133n (n indicates the axis number (1 to 8).)
The battery voltage supplied to the position detector dropped.
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.
The regenerative level of the additional axis has risen to 80% or more.
Check the regenerative capacity and parameters for the additional axis.
If it comes back, contact your service provider. Regeneration resistance may be disconnected.
The overload level reached 95% or more.
Check the load weight and the robot for collisions, etc.
The counter of absolute position is illegal.
Confirm whether the connection of encoder cable and the battery voltage of arm is falling.
A parameter was set exceeding the setting range.
The parameter has not been changed. Reset the correct value. If it comes back, contact your service
provider.
An instruction to remove the axis was issued by the controller.
Cancel the instruction of removing axis.
The emergency stop command has been input from the RC
Release the emergency stop state
Regeneration at the limit has occurred frequently
Check the regeneration capacity
The power was momentarily interrupted
Check power specification, and wiring of power and external emergency stop
The regeneration level reached 80％ or more.
Lower the robot's movement speed.
If it comes back, contact your service provider. Regeneration resistance may be disconnected.
The servo turned ON while the main circuit power was OFF
Turn the main circuit power ON
Trouble occurred in the current processing processor.
Turn the power OFF and ON once. If it comes back, contact your service provider.
The power was momentarily interrupted at the power supply
Check power specification, and wiring of power and external emergency stop
Overcurrent in the power module in the power supply.
Check the AC power line. If it comes back, contact your service provider.
